Basic Questions
Q: What is the best source of information about my CRX?
A: The FACTORY service manual is invaluable. I suggest that every CRX owner
get a FACTORY manual. FACTORY manuals turn up on eBay and are well worth the
price.
Q: Most web sites do not list parts for the early CRX, can I use parts from
the 1988 and newer models on my car?
A: There are not a lot of interchangeable parts between the 1st Generation CRX
(1984-1987) and the Second Generation CRX (1988 and later); the engine, transmission,
suspension and body are different. Some brake parts and most fasteners are interchangeable.
Q: How fast can I go?
A: How much money do you have? Anything is possible if you throw enough money
into the project.
Q: Can I put 16" wheels on my 1st Gen CRX?
A: You could, but it is not a good idea. Long story short: Racing CRX's are
shod with wide 13 inch wheels and tires. I have a set of 205/50/15 tires on
15x7 wheels for street use and that is as large and wide as you can go. 195/50/15
is better for street use. For racing I use 205/60/13 tires on 13-inch rims.
Q: Where can I get specs for the First Gen. CRX engine?
A: www.quickhonda.net/specs.htm
Q: I am not certain I know what model (HF, DX, Si) my car is, how can I tell
A: This answer comes from Mr. Kwicko- Check the VIN. It should read something
like "JHMEC13xxHS000001". The first (bold) "x" marks the
digit for the model. 1 = HF, 2 = Std (or DX), 4 = Si. Now, if you're still unsure,
check the engine code. On the DX and HF models, there is a plate on the
front radiator support, on the driver's side of the car (under the hood, behind
the headlight, facing straight up at you as you look at the motor). D15A2 is
the carb'd 1500cc engine. On the Si, the plate is on the opposite, or passenger,
side. It will be a D15A3 motor, which is the 1500cc Fuel Injected engine.
Q: Where else can I find parts online?
A: Used, and sometimes new, parts come up on auction sites like www.ebay.com.
Check often. For new OEM parts try www.hondaautomotiveparts.com. Also, check
my list of links at the end of this file.
Q: What grade of gas should I use in my CRX?
A: You can run any modern engine on any grade of gasoline. Whatever type of
gas you use, reset the ECU to that type of gas. This involves removing electrical
power to the ECU to "erase" its memory and then restarting the already
warm engine and letting it idle for a few minutes WITHOUT touching the gas pedal.
I am of the school of thought that says, put the highest octane gas you can
find into your car. I own two D series 1.5 liter Hondas and I can tell you that
the difference between high octane and low octane is VERY noticeable. If you
are cheap and do not care how much power your engine makes, put the cheapest,
lowest octane gas you can find into your car. If you really want to maximize
the power potential of your
engine, put the good stuff in. I add a bottle of octane booster to every tank
as well.
Q: Are all 1st Gen CRX parts interchangeable?
A: The 1st Gen was first sold as 1984 model in 1983. For the 1986 model year,
the CRX got a slightly different interior. Honda also changed the electrical
connectors in the 1986 model, so some electrical parts from the 84-85 car will
need modification to fit on the 86-87 cars. There are some subtle differences
in the front fenders, front and rear bumper covers, body cladding, and header
panel between years and models.
Q: Could I put the Honda 4WD system from a 1985-1987 Civic Wagon on my CRX?
A: The Honda 4WD only sends 10% of the engine power to the rear wheels, so the
extra weight and hassle is not justified. But, you can bolt an Integra D16 engine
directly to the 4WD Civic Wagon transmission so you could build a very strong
Civic Wagon if you wanted.
Cheap Modification Questions
Q: Nobody seems to sell a Cold Air Intake (CAI) for my 1st Gen. Can I make
my own?
A: A few manufacturers used to make a CAI for the '85-'87 fuel injected Si model,
but they have been off the market for some time now. Occasionally a used example
will show up on eBay. The DX and HF are completely out of luck, nobody ever
made a CAI for them. I have made my own CAI from some pieces of plastic piping
(the thick black plastic pipe that is used as waste pipe) and a K&N filter
with a 3 ½ inch opening that attaches with a pipe clamp, K&N part
number RX-4140.
Q: I am on a budget, how can I make cheap modifications?
A: The 1984-1987 CRX, the 1984-1987 Civic and the 1986-1988 Integra are basically
the same car under the skin. Junkyard parts are cheap. See the Suspension section
for more details.
Q: I would like to lighten my car.
A: The obvious things to discard are interior trim, sound deadening and the
A/C system. Under the front and rear bumper covers are heavy steel beams that
are the actual bumpers. If you do not plan on hitting anything, these heavy
steel beams can be hack sawed out. If you are planning on having an accident,
a car that weighs less than 2,000 pounds should not be your vehicle of choice.
Buy a Volvo.
Q: Strut tower braces will stiffen my car and improve my suspension's response,
can I make my own?
A: Yes, you can. You could buy front and rear strut tower braces from online
seller www.cyberauto.com or www.greddy.com. You could make your own with imagination
and some basic hand tool skills. Go to the hardware store and look for sections
of "Uni-strut." This is predrilled steel that looks like the stuff
the highway department uses to mount roadway signs.
Q: Can I relocate my battery?
A: I relocated my battery to behind the passenger's seat. Rather than buy an
expensive kit, I used one cable from a set of jumper cables to connect the battery
to the engine compartment. I bolted the ground cable to the passenger's seat
bolt and I ran the positive cable under the console and through the firewall
via a factory cut hole that is just above the passenger's feet. The firewall
hole is plugged with a rubber "stopper" that
I drilled a hole in and passed the positive cable through.
Q: Where can I get a set of wider, lighter wheels that will not break my wallet?
A: The Junkyard. Water-cooled VW wheels are the same bolt spacing and nearly
the same backspacing as Hondas. Every good junkyard has a ton of VW alloy wheels
that are lighter and wider than your stock wheels.
Q: Racing tires work great but they are expensive, do you have a cheap source?
A: Every racetrack has a tire facility. The rich racers take perfectly good
tires off their racecars and put on new tires. I bought a set of good, used
race tires for $30 each at my local racetrack.
Body and Cosmetic Questions
Q: Where can I buy a body kit for the early CRX?
A: Mugen made a body kit that is no longer being manufactured. www.housemanautosport.com
makes a pretty good copy of the Mugen body kit. www.andysautosport.com/crx_ground.html
sells a body kit also.
Q: The front piece between the headlights and my fenders are cracked, where
can I get replacements?
A: www.certifit.com or you can get the pieces from Honda. Honda quality is better.
Certifit is cheaper
Q: Who sells clear corners, taillights and turn signals for the early CRX?
A: As far as I know, no aftermarket manufacturer is selling clear or altezza-style
lights for the early CRX. Honda sold the early CRX with clear corners in Europe,
the JDM models have amber lights like the US model. Try contacting Honda dealers
in Europe like www.crown-honda.co.uk/parts/index.htm. The only trick to installing
Euro-spec clear corners: the US corners have two light bulbs in them, the Euro
corners only have one. I have drilled a hole in the back of the Euro-spec corners
to allow the second bulb to be mounted. Euro-spec corner lights are technically
illegal in the US. The 1984-88 Toyota pickup truck turn signal lights are very,
close in size to the Honda turn signal lights. A set of aftermarket clear lens
for
the Toyota truck will fit nearly exactly over your Honda turn signals.
Q: What seats will bolt into the early CRX?
A: Generally speaking, seats can be swapped from model to model if you stay
within the same year. For example, I used to have 1987 Prelude seats in my 1987
CRX Si. The bolts and tracks are the same width. Honda changed the seat track
width on nearly all their cars in 1988, so later seats need to be modified to
fit.
Some people have installed the more comfortable later model CRX seats by relocating
the seat rails to fit the mounting location of the early CRX. The only draw
back is that the new seats are a little taller and headroom is compromised.
Engine Questions
Q: I want to make my car a hybrid and install a bigger, stronger engine.
A: At the top of the family tree for the D Series, DOHC 1600cc, 16-valve engine
is the JDM spec ZC engine of 135 hp. Next in line was the Euro-spec D16A8 which
makes about 120 hp. In the US, we got the D16A1 Black Valve Cover version in
the 1988-89 Integra, with 118 hp. And at the end of the line is the D16A1 Brown
Valve Cover version in the 1986-87 Integra with 113hp. Many people refer to
the 1986-89 Integra engine as being a ZC, but this is not technically correct.
ZC is Honda's term for the top rated version of its engine. If you can find
all of the JDM parts, you could build a USDM D16 into a ZC. But those parts
are rare and probably expensive.
The Brown and Black valve cover version of the DOHC D16 engine are very easy
to install. Basically, cheap, used Integra parts bolt straight into a 1st Gen
CRX. HAS Sport makes a kit to install the later B Series engines into the 1st
Gen, but it is expensive.
The 88-89 Integra engine (black valve cover) is slightly more powerful than
the 86-87 models for two reasons: Better intake manifold & it has domed
pistons. That's it, everything else besides the ECU & distributor is the
same. The 86-87 Integra rods are a little thicker than the 88-89's rods. Parts
are interchangeable between all versions of the D16.
The BROWN Valve cover is equipped with:
-FLAT-TOP pistons
-Thick rods
-Square styled intake manifold
-Vacuum advance ignition with external coil
The BLACK Valve cover is equipped with:
-Domed pistons
-Slightly lighter rods
-Rounded intake manifold.
-Electronic advance distributor with internal coil.
ACTUAL SWAP INFO:
Engine Mounts (total of 3 mounts on 84-87 Civic/CRX's):
Use the stock Civic/CRX mounts on the rear cross member & front timing-belt
side.
Use an 86-89 Integra tranny mount for the tranny. The Civic/CRX tranny mount
will make the motor sit crooked if you use it, so don't.
Axles:
Use a complete set of 86-89 Integra axles including the intermediate shaft.
Knuckle/hub assembly:
In order to use an 86-89 Teg' engine + transmission, you have to use the 86-89
Integra
knuckle/spindle assembly so that you can utilize the Integra 3-piece axles.
The 86-89 Integra axles DO NOT plug into 84-87 Civic/CRX knuckle/spindle's.
Shift linkage:
Use a complete 86-89 Integra's shift linkage.
Wiring harness:
Use the 1st Gen CRX Si's wiring harness. Plugs right into the 87 Integra sensors,
injectors, & distributor.
Distributor & ECU:
Make sure you use an 86-87 Integra ECU & Distributor. That's the only DOHC
ECU (besides a JDM one) designed to work with a Vacuum Advance Ignition (distributor)
which only came on the 86-87 Integra's.
***Do not use an 88-89 Teg' ECU or Distributor****
Simply because it has an internal coil ignition just like all the 88+ civic/CRX/Integra
use, which is completely different than the 86-87 ignition components.
Q: Can I put a fuel-injected engine into a car that currently has a carburetor?
A: Fuel injection requires a pressurized fuel system that the carburetored cars
do not have. You will need to change the fuel system and a large portion of
the wiring harness to put a fuel injected engine in your car.
Q: Can I put a B series engine in my 1st Gen CRX?
A: www.hasport.com makes the kit to do it. Bring a bag of money.
Q: I want a more aggressive ECU (Computer) or a chip and fuel injectors to
increase performance in my Si.
A: As far as I know, no one makes a chip or a high performance ECU for the 1st
Gen CRX Si. The 1986-87 Integra ECU and fuel injectors will plug right into
your car. The Integra ECU will let you rev higher and the injectors will flow
more fuel. I suggest that you also install a fuel pressure regulator, a fuel
pressure gauge, an air/fuel ration meter and a honed throttle body for increased
airflow to match the increased fuel flow.
Q: How can I make more power in my fuel-injected engine?
A: If you get more air and fuel into the engine, the engine will make more power.
To supply the "more fuel" I put in a set of 86-87 Integra injectors
that I had cleaned and balanced. To get the "more air" I built a better
breathing throttle body out of a stock, twin choke throttle body. I opened the
throat of the primary choke from 20mm to 26mm and I also smoothed the path to
both chokes. Using a Dremel with a cutting wheel I cut the "lip" of
the primary throat so that it was even with the "shelf" that surrounds
the primary throat. I then drilled down the primary throat on a drill press
and with a 61/64" drill bit. Finally, I cleaned every thing up with a grinding
bit on a 3/8" drill and a wire brush on the same drill.
Q: I was thinking of installing an undersized crank pulley.
A: Don't bother. I had one on my car and it did nothing to improve performance,
all they do is make your alternator and A/C compressor spin slower. The stock
crank pulley is designed to work with your engine and should not be changed.
Q: My idle fluctuates up and own by a couple hundred RPM on my fuel injected
engine.
A: Your Throttle Position Sensor (TPS) has gone bad. This is the portion of
the throttle body that tells the ECU how far open the choke plate is. Normally,
if the TPS goes bad you must replace the whole throttle body because the TPS
is attached with slot-less screws. But, you can cut slots into the TPS screws
with a file or a Dremel tool and unscrew the TPS. Swap in a junkyard TPS and
that should fix your problem.
Q: I have a DX, can I put the better breathing Si head on my DX block (the
Si and the DX share the same EW block).
A: This answer comes from the Mk1CRX discussion group on Yahoo Groups: I would
definitely go for the Si head. I have done it and I was amazed. I shaved my
Si head .040 to recover lost compression, but it's not necessary, you'll just
have low compression. If you do shave the head, a cam gear is most beneficial,
because shaving the head automatically retards cam timing and the gear will
get it back to stock or preferably a bit advanced, good for mid range power.
I went the dual sidedraft route, very simple manifold
and no worries. Weber Carbs: they are unmatched in the world of carburetion,
but very,, expensive, and a PITA to tune and sync the first time, along with
being very sensitive to dramatic weather changes. Weber makes sidedrafts, in
several varieties. The most common [and arguably the best carb of any configuration
ever made] is the DCOE. They're a twin carburetor design, meaning that there
are two distinct throats that act independently of one another, but share the
same body. They can be found with 40, 45 and 52mm throats [I think there are
more, but those are the most popular, esp. the DCOE 40]. The easiest way to
get more power from an engine is to allow it more air with the proper amount
of fuel. For my engine, I chose twin DCOE 40 Webers [that's four (count 'em,
4) air horns], with a DC sports header. Mikuni's are nice, easily tuned, but
Webers blow them out of the water if they're jetted even close. You can find
more models and prices of Weber carbs and carb kits at: www.carbs.net
Q: Can I put a single carburetor on my Si head?
A: Rip and Tear Auto from the CRX Resource answers: The carb is a Weber 32/36
DGAV. This is the carb that is used in the single Weber conversion kit for carborated
1st gens. We had to change every jet in the thing. Right now it's got:
150 primary main
155 secondary main
75 primary idle
60 secondary idle
55 double shot accelerator pump jet
160 primary and secondary air correctors
It still needs a bigger secondary idle jet (don't have one yet) and I am still
playing with the air correctors.
The injector holes are just taped and plugged with standard brass plugs. I originally
used the DX cam in the Si head so I could run my stock fuel pump, but have since
switched over to a corroborated Accord pump. The Accord pump is electric, and
has a built in regulator. Vacuum lines? I have vacuum lines. Well, one anyway,
running from the back of the carb to my vacuum advance on my distributor. No
it is not smog legal, but hey you can't have every thing. As far as the design
of the adapter plate, I never drew up anything nice because I didn't need to
since I was making the plate my self.
Q: Where can I get stiffer than stock motor mounts?
A: Mugen used to make a set, but they are currently unavailable. But you can
cheaply make your OEM mounts stiffer than stock by filling the hollow spaces
in the rubber mounts with polyurethane (3-M polyurethane adhesive works well).
Clean all of the surfaces inside the OEM motor mounts carefully,
apply the windshield adhesive, and let it cure for about 48 hours before reinstalling.
Brake Questions
Q: Can I put rear disk brakes on my car?
A: Yes, but you will need to graft the rear axle from an Integra onto your car
to make it happen. Another alternative is to replace the iron rear drums with
aluminum drums from the HF model. This saves weight and works just as well as
the Integra rear disks. You will have to change the rear brake backing plate
to a HF plate to make the aluminum drums fit, but that is a relatively easy
job.
Q Will the Integra's larger front caliper, and rotors bolt right on to my CRX?
A: Yes, and the Integra brakes will fit under 13" wheels.
Q: Should I use slotted or cross-drilled rotors?
A: For street driving, the plain OEM style rotors are just fine. Slotted rotors
allow the gas that forms between the pad and the rotors to escape. If you do
a lot of hard driving in hot conditions slotted disks may be good for you. Cross-drilled
also do that and are lighter. But cheap cross-drilled rotors are subject to
cracking. Expensive cross-drilled rotors are cryogenically treated to prevent
cracking.
Q: I am not certain my brake booster is OK, how do I check I?
A: From the Mk1CRX group on Yahoo groups: To test the brake booster, try the
following procedures: 1. With the engine off, press the brake pedal several
times. Then press it hard and hold that pressure for 15 seconds. If the pedal
sinks, a brake line, wheel cylinder or master cylinder is faulty. 2. Start the
engine with the pedal pressed. If the pedal sinks slightly, the booster is working.
if the pedal height doesn't vary, the booster or check valve is faulty. 3. Press
the brake pedal with the engine running. Then stop the engine. If the pedal
height does not vary for 30 seconds the booster is OK. If the pedal rises, the
booster is faulty. 4. With the engine off press the pedal several times with
normal pressure. When the pedal is first pressed, it should be low. On consecutive
applications, pedal height should gradually rise. If pedal height does not
vary, check booster check valve. The check valve is the thing in the big vacuum
line going to the booster, which is below the master cylinder in the engine
compartment.
Transmission Questions
Q: Who makes a short shifter for the 1st Gen CRX?
A: I have had both the Pacesetter (terrible) and the DC sport (great) short
shifters in my '87 Si. If you install a short shifter, the effort to change
gears increases. Something to get used to. The '88 and later short shifters
will not fit the '87 and earlier cars. I used nylon washers in the connecting
bolt of the shifter to smooth shift action.
Q: What is the difference between the cheaper Phantom Grip Limited Slip Differential
(LSD) and the more expensive LSD from OPM?
A: Shane Portnoff answers: CRE and OPM make a limited slip, $650. The only difference
between theirs
and phantom grip is they put clutch plates in between the differential side
gears and the carrier. The spring package is sandwiched in between the two side
gears putting pressure at the clutch plates, creating "limited slip".
Of course the clutch material will wear out also, but that is replaceable and
probably cheaper than a new differential assembly. The phantom grip is just
the spring package, so the friction created is between the side gears and the
differential carrier. The friction coefficient must be kind of unpredictable
plus the gears and carrier assembly will eventually wear out. Also there will
be ground up metal inside the trans.
Q: Any tricks to installing a Mugen Limited slip Differential?
A: Yes, the Mugen LS diff is slightly shorter than the stock unit and it will
rub against a "rib" inside the transmission case. The solution is
to use a pair of pliers to snap the rib off and file down the rough edges. Use
75w90 transmission oil. Break in the new diff by driving in a series of figure-eight's
in a large parking lot. Drain the transmission oil and replace with new 75w90.
King Motorsports recommends Redline MT90.
Q: What are the gear ratios of various 1st Gen CRX models?

Suspension Questions
Q: I want stiffer front torsion bars.
A: Are you sure? Unless your car is a dedicated racer, or you have put a heavier
engine in, the stock torsion bars are stiff enough in the front. People who
have put stiffer front torsion bars in their cars report that the
ride becomes very hard and uncomfortable for daily driving. You can buy thicker,
stiffer torsion bars from OPM Motorsports, they sell 22mm and 27mm torsion bars.
Check the list lower in this section for torsion bar and sway bar choices.
Q: What is a good replacement for the rear springs?
A: You have two choices. The best, and more expensive choice is to buy Ground
Control coil overs which come with a variety of Eibach springs. Or, you can
buy a set of Integra or Civic Wagon springs from the junkyard. On my car, I
have the stock torsion bars and a set of Integra springs with one coil cut off.
This combination works well.
Q: From what Honda products can I source sway bars and torsion bars?
A: Ballade, from the CRX Resource, provides this handy list:
Both the Si CRX and DX CRX had the same suspension Specs
Stock 84-87 SI&DX: Front sway bar 16mm
Rear internal sway bar 15mm
Torsion bar 20mm @24.5" Long
Civic Wagon 2WD: Front sway bar 20mm
Rear internal sway bar 15.5mm (won't fit into CRX beam axle due to end link)
Torsion bar 21mm @22.5"Long (shorter then CRX bar, need wagon torque tubes)
Thicker rear springs (cut to fit)
Civic Wagon 4WD: Torsion Bars 21mm @ 24.75" Long (will work with CRX Torque
tubes.)
Integra: Front sway bar 19mm
Rear sway bar 17mm
Torsion bar 22mm they are longer then CRX bars and won't fit in lower arms
Thicker rear springs
Integra SE Rear internal sway bar 19mm
Q: What is the correct way to lower my 1st Gen CRX?
A: First the basics- The early CRX has torsion bars, rather than springs in
the front. Honda used T-bars to save space and allow a lower front profile.
In the rear, there is a beam axle located by trailing arms and a Panhard bar
with coil springs. Inside the rear axle is a torsion bar that acts as a rear
sway bar. In the front, there is a conventional sway bar. To lower the car,
you need shorter springs and reset torsion bars.
***Important Note*** When you lower the rear, the axle moves closer to the driver's
side. To correctly reposition the rear axle to the center of the car, you will
need an adjustable panhard bar. They are available from www.opmmotorsports.com.
Coilovers are the best way to lower the rear. www.ground-control.com sells a
couple different options for coilovers. If you are cheap (like me) you can use
the rear springs from the Civic Wagon or the Integra and cut one coil off. Cutting
coil springs is generally not a good idea, but the simplicity of the CRX rear
suspension allows a measure of crudeness. In the front, the front torsion bars
can be adjusted lower about 1/2" by loosening the adjustment nut underneath
the car on each side. To get the front really low, you will need to take the
torsion bars out and reposition them 1 notch lower. If your car is a 100% racecar,
get the thickest torsion bars you can find (OPM Motorsports has a selection).
For street and track use, the T-bars out of the 4wd Civic Wagon are thicker
than the CRX and usable on the street. Lowering the car reduces suspension travel.
You can increase suspension travel by filing off the brake line bracket on the
front struts and positioning the struts 1-inch lower in the front knuckles.
Camber plates will also give you some more suspension travel. Adjustable struts
are expensive, but they allow you the opportunity to fine-tune your suspension.
If you are not racing, maybe you do not need adjustable struts.
Increasing camber and caster will wear out your tires faster, but will help
you on the racetrack. An alternative to camber plates is to bolt on the lower
arms from an Integra to get about 1 degree of negative camber. Caster can be
added by loosening the sub-frame, pulling the entire front end
forward with a winch and then re-tightening the sub-frame. Suspension Techniques
sells a bolt on rear sway bar, which is a good idea to add to your car. There
are many opinions about the front sway bar on the
CRX. Some people suggest removing it completely, others advocate using the thicker
Civic Wagon front sway bar. Changing the front sway bar is a PITA. For street
and Autocross use, I kept the stock bar with new bushings.
Q: What is the best way to increase negative camber in the front end.
A: You can buy a camber plate from OPM Motorsports (expensive) or you can bolt
on the lower arms from a first gen. Integra which you can buy from a junkyard
(cheap). The Integra arms are a little longer than the CRX arms so you get about
1 degree of negative camber that way, but you have no real adjustment. The camber
plates give you the option to dial in as much or as little camber as you want.
Q: How can I increase caster?
A: Lightspeed used to make a camber plate that included a caster adjustment;
but they are hard to find. One trick you can use is to loosen all of the bolts
that hold the sub-frame to the car and then use a winch to pull the sub-frame
forward a bit. Re-tighten the bolts and you have just increased the caster.
Q: I want to change the camber and toe of my rear wheels.
A: Moog makes a set of shims to make these adjustments. Between the trailing
arm and the rear hub are four bolts holding everything together. A guy on the
island of Malta has told me that he made the adjustments to his rear suspension
with a couple of washers between the trailing arm and the top two
bolts. And he got some toe out by putting an extra washer into the front two
bolts.
Q: Quicker steering?
A: The HF model has a quicker steering ratio rack and pinion so you can put
that into your DX or Si.
Q: Could I make my own adjustable Panhard Bar?
A: Yes, the following is from the 1st Gen Integra web sire www.g1teg.org
How To modify 84-87 Civic/CRX and 86-89 Integra Panhard bar. To make this mod
simpler, I suggest picking a used panhard bar from a wrecking yard. You will
also need about 3' of 3/4" diameter pipe, and a
suitable sized bolt to fit inside of the above mentioned pipe snuggly. The bolt
should be 3-5" in length, and you will also need two nuts to fit the bolt.
I used a 9/16" bolt because it fit snug in the pipe I used, this size
will vary depending on the pipe you use. This mod does require welding, if you
cant weld it, any shop with a MIG welder should be able to weld this for you
for a small charge, 1/2 hour of shop time max. Since you will be welding to
the parts of the old panhard bar, you will need to remove the bushings, otherwise
they will be burned during the welding. I strongly suggest polyurethane bushings
as a replacement. Now it is very important to measure the overall length of
the panhard bar and keep note of it. The easiest way to do this is to use a
piece of cardboard and trace out the panhard bar. Once the panhard bar has been
measured, cut a section from the middle about 1', leaving some of the channel
at both ends. All excess paint needs to be removed for welding, sand down the
inside of the channel to expose clean metal. Also during welding the undercoat
paint will peel and burn off, to get rid off the undercoat just burn it off
with a propane or acetylene torch. Let the pieces cool off. Now the bolt you
will use for the adjustment should fit snug in the pipe. Cut only the head off
of the bolt with a hacksaw. Spin on one of the nuts 1 or 2 turns. Measure the
remaining threads left for the nut to spin onto, keep note of this measurement
as well as mark the bolt. Now the smaller bushing end (the frame end) is where
I put the adjustment, to make it possible to adjust it without removing the
whole panhard bar. So this part of the old channel can be cut a little shorter
than the bigger bushing end. Now lay the two pieces of the original panhard
bar onto the cardboard you traced it on to. Measure the distance between bushing
sleeves, subtract the amount of adjustment left on the bolt and this is the
length of the pipe overall. Cut the pipe to length, then cut it into 2 sections
one short and one long. Now assemble everything on the cardboard, sliding the
pipe into the channel until it bottoms against
the bushing sleeves, setting the bolt partially into the short tube at your
earlier mark and resting the nut against the long tube. Make sure you allow
for the adjustment to mostly shorten the panhard bar, unless you plan on lifting
your Teg Now double check your overall length, and mark all the joints with
a indelible marker or chalk, so you know where to line things up when welding.
It is crucial to keep the pipe straight/square in the channel while welding.
Use a vice to hold the channel, then place the appropriate
pipe in the channel, making sure the pipe lays flat against the top part of
the channel, double check the marks you made earlier then use the vice to squeeze
the channel so that it clamps the pipe in place. Check your marks and begin
welding. Repeat this process for the other end. Now insert the bolt into the
short piece of pipe and line it up with its marks, then weld it in place. Last
is the nut to be welded on the long piece, this is a little tricky to square
up. Set the pipe straight up and down in the vice and place the nut on the end,
Tack weld the nut to the pipe on one side only. Using a square check and adjust
the nut as required and weld completely. Once it has cooled from the welding
spin on the second nut all the way, this is the lock nut. Assemble the rest
of the panhard bar, paint it and install your new bushings. You can now install
this in your car and adjust as necessary. Don't forget to tighten that lock
nut.
Q: How would I install a set of aftermarket torsion bars?
A: This answer comes from the Mullinator's web site .http://mybiz.aintnoneofyour.biz/crx/
Set the emergency brake and loosen the front lug nuts. ? Raise the car using
the bump under the radiator, in the center of the front of the car. This positioning
will allow more clearance for your work area. But remember; most folks do not
consider working under a car supported only by a jack as safe. You should use
jack stands. I warned you. * Remove the wheel. * Remove the 17mm screw that
locates the strut cartridge in the steering knuckle. Jiggle the strut to make
sure it's free of the knuckle. Also remove
the 17mm height-adjusting nut and the dust cap on the front of the torque tube.
* Hit the newly revealed front opening of the torque tube w/ PB Blaster. * Remove
the 2- 12mm screws that hold the cup at the back of the torque tube to the frame
rail. * Remove the cup. It is held on pretty well even after you remove the
screws-- here's the best method for removal I've found, so far. Hit it with
PB Blaster. Liberally. Then alternately tap the top and bottom lips of the cup
(the metal part, not the rubber insert) with the edge of your large flat-blade
screwdriver. I found my 3lb hammer worked much faster than my 16oz. Patience
will pay large dividends. Trust me, it will come off. * Remove the circlip from
the rear end of the t-bar.
* HOLD SOMETHING WOODEN LIKE A BROOM HANDLE OR A DOWEL against the back of
the bar and hammer it forward. Again, a 3lb short-handled hammer works wonders
here. You need to move the bar just far enough forward to reveal the wire clip
at the front. Do not bash the bar past this point, it will make it more difficult
to remove the bar later. * Remove the front clip and tap the bar all the way
out, toward the rear of the vehicle. Remember this: if you encounter much resistance
when attempting to move the bar, you have done something wrong. Double-check
that the strut cartridge is free and that you removed the height-adjusting nut.
* Remove the torque tube. Once the bar is out, the tube slides to the rear and
off of the car. * If you choose not to machine the torque tube, match your aftermarket
bars to the stock ones. I got bars stamped L and R, but they were actually two
left bars. This will not affect owners who modify the torque tube. Note that
after they learned of my experience, OPM diligently inspected the rest of their
stock for mistakes and informed the manufacturer to double-check their shipments.
Evidently my set was just a fluke. * Install the circlip on the rear of the
bar. The rear has the L or R stamping and is slightly larger in diameter than
the front. * Set the torque tube in place. Slide it as far forward as you can.
Make sure you position the hole for the height-adjustment mechanism over the
bolt onto which the nut will install. Do not install the nut, yet. * Grease
the splined ends and insert the bar. You will have to align the key on the front
end of the bar with the appropriate keyway on the arm that bolts to the lower
control arm. * Now rotate the torque tube until its adjusting arm is about halfway
up the adjusting bolt. Carefully engage the rear of the bar with the splines
in the torque tube. If you apply very slight forward pressure with your hand,
you will feel the splines as you wiggle the torque tube. Once you have engaged
the splines, USE THE WOODEN DOWEL and your hammer to slide the bar forward until
the circlip hits the tube. If you encounter more than moderate resistance, you
are doing something wrong. If you go gorilla on the t-bar, you are going to
have to buy a whole new set. Don't even think about getting a replacement torque
tube. BTDT. * Don't worry about the front clip. I don't see the need to fuss
with it. And if you don't, removal will be much simpler in the future. Install
the front dust cap and the height-adjusting nut. * Apply a light coating of
grease to the torque tube cup and the rubber insert and reinstall. * Reinstall
the screw that locates the strut cartridge in the steering knuckle. * Reinstall
the wheel with the lugnuts finger-tight. * Put the wheel back on, drop the car,
and set the height-adjusting nut as best you can. Don't worry about it too much,
the height-adjustment procedure takes a few tries before everything is correct.
* Tighten the lugnuts. not a definitive
