list taken from Moose from SOHCHonda.

This is to be the most accurate from what i know between the 88-95 civic. never really tried with the 96-00 civics. I would say that 99% 88-00 parts are changeable.(honda tends to do stuff like that). If you know of some errors that got past me, or dealt with the 96-00 civics and parts interchange please lmk and I will update what has been missed.

Keep in mind switching stuff out will work, but it may change your offset, toe, and camber.

Front

Front upper control arm (UCA)
-(UCA) can be swapped for a 94-01 Integra Upper control arm … no performance advantage BUT it is easier to find newer Integra ones at the Wreckers.
-Note: The ball joint in the UCA is not replaceable … Honda does not sell the ball-joint alone, you generally replace the entire A-Arm
-The UCA's can be swapped Left to right, BUT since the upper balljoint is not symetric (front to back) this swap will cause an increase in Caster.

Front lower Control Arm (LCA)
-LCA can be swapped for a 94-01 Integra Lower control arm…. no performance advantage BUT it is easier to find newer Integra LCA's at the Wreckers.
-I have also found that it is cheaper/easier to swap in a nice new 99-01 Integra LCA than to replace all the bushings
-Integra's came with front sway bars, as did some Civics, thus have the necessary flange to attach the sway-bar end-links. So if you need to change a sway bar equipped Civic LCA, make sure that the donor car also had a sway bar

Front Steering knuckle
-There are two types of front steering knuckles found on a Civic. The knuckles found on a civic with 9.5" diameter brake rotors and the knuckles found on a civic with 10.2" diameter brake rotors. These two knuckles are not compatible with one another, different brake caliper brackets, bearings, and hubs.
-The 10.3" equipped 90-91 civic 4d(non-abs), 95-97 del sol vtec(abs), 99-00 Civic Si(abs) knuckles are the same as the 10.3" 94-01 Integra(RS non-abs, LS/GS/GSR ABS) (except ITR) front steering knuckles.
-The Other Bolt-on option for EG Civics' is the Integra Type R … the 96 JDM 4x114 lug, or the 97-00 5x114 5 lug 11" setup will bolt up without any issues.
-There is one final difference between front knuckles … ABS. ABS equipped cars NEED ABS hubs/knuckles for the sensors to work, so make sure if your car is ABS equipped that you get a ABS equipped Knuckle

Front Shocks,
-ANY 88-00 Civic or 94-01 Integra (including the ITR) front shocks will bolt up to the 5th Gen.
-4th Gen front shocks will bolt up ONLY if you use the 4th Gen. lower shock fork. 4th Gens use a shock body that is smaller so you have to use fork than came with the shock.
-Further 4th Gen note: 4th Gens. have less suspension travel than 5 or 6th Gen civics, thus the shock bodies are shorter than 5th or 6th gens, so you can run out of shock travel, particularly when lowered, and could bottom out with 4th Gen shocks in a 5th or 6th Gen civic.

Front Springs
-ANY 88-00 Civic or 94-01 Integra front springs will bolt up to the 5th Gen, but there will be a difference in ride height depending on what spring you use.
-Integra Springs generally have a higher spring rate than the Civic springs (stiffer) but not by much.
-The ITR on the other hand has a much higher rate spring than a regular Integra or a Civic and a EG sits about 1"lower than stock … so it is a nice upgrade for 5TH GENS

Front Sway-bar
-All 88-00 Civic and 94-01 Integra sway-bar may be swapped in as long as you get the associated end-links, bushings and D-brackets.
-If your car did NOT originally come with a sway bar you have to swap in the LCA's from a sway bar equipped 88-00 Civic or 94-01 Integra

Front Sub-frame
The 88-00 Civic and 94-01 Integra front sub-frames are compatible with one another, but there seems to be a difference between sub-frames the manual steering and power steering equipped cars …I have not been able to confirm or deny this yet

Front Sub-Frame Brace
-The 95-97 DelSol Vtec (DOHC) and 94-01 Integra front sub-frame brace will bolt up to ANY 92-95 Civic sub-frame. This helps stiffen up the lower suspension mounts point s and do NOT hang down below the car like most aftermarket lower braces (not sure if 88-91, or 96-00 never tried)


REAR

Trailing arms
-There are two types, Disk brake equipped, and Drum brake equipped.
-The Disk brake equipped trailing arms are compatible with all Disk brake equipped 88-00 Civic trailing arms, and 94-01 Integra trailing arms.
-These disk brake trailing arms are also VERY similar to 88-00 Civic and 90-93 Integra rear disk trailing arms … there is only a small difference in a couple of accessory brackets I believe.

Upper control arms (UCA)
I "think" they are compatible with the 94-01 Teg … but I am not 100% yet There is some discussion if the length of the arm varies by Generation … but the mounting points are the same (chassis and trailing arm)

Front compensator arms (toe arms)
-They are compatible with the 94-01 Teg Compensator arms

Lower control arms (LCA)
-There are two types … sway bar equipped and non sway bar equipped LCA's
-All 89-95 Civics/CRX's EXCEPT the Civic EX-V, CRXsi, and DelSol Vtec have similar LCA's that do NOT have the mounting point for a sway-bar end-link
-The DelSol Vtec, the 89-91 CRX si and the 92-95 Civic EX-V have a rear sway bar and as a result their LCA's have mounting points for the Sway-bar end-links.
-The DelSol Vtec and EX-V LCA's are the SAME as the 94-00 Integra LCA's (non ITR) as all Integra's came with rear sway bars.
-The Sway bar equipped LCA's can be swapped for the non-sway bar equipped LCA's with any problems
-ITR's and the 88 CRX use a different style LCA … the shocks lower mounting is a "EYE" style where the shock goes thru the LCA and is bolted thru …
-The Rest of the Civic's/Integra's use a "Shackle" style lower shock mount where the shock bolts around the LCA.
-So if you want to use 88 CRX or ITR rear shocks on your EG civic you must use ITR LCA's
-Note: in Japan most 92-95 Civics' used the ITR style LCA

Shocks
-ANY 89-95 Civic or 94-01 Integra (except ITR) rear shock will bolt up to the 5th Gen. The 88 Civic or ITR rear Shock will bolt up but you need to use the ITR style 88 Civic LCA or the ITR LCA
-Further 4th Gen note: 4th Gens. have less suspension travel than 5 or 6th Gen civics, thus the shock bodies are shorter than 5th or 6th gens, so you can run out of shock travel, particularly when lowered, and could bottom out with 4th Gen shocks in a 5th or 6th Gen civic.
The 96-00 Civic Shocks will bolt up BUT you need to narrow the LCA Shock bushing as these shocks have narrower lower shackles.

Sway-bars
-Rear sway bars came only on the 88-95 Civic/CRX Si, EX-V, and the DelSol Vtec. So these sway bars can be bolted up to any non sway bar equipped EF/EG …IF you use the appropriate LCA's. End-links, D-brackets, bushings, and bolts.
-There are holes to mount the sway-bar bracket to the rear sub-frame … but there might not be any captive nuts for the bolt to attach to, but you can add these easy enough.
-The Sway bars from the 94-01 Integra's can also be bolted up to a EF/EG, BUT the 22mm rear bar WILL tear out the rear sub-frame unless it is reinforced with a Beaks kit or similar setup.

Sway-bar Sizes
-92-95 Civic Si/EX, 13mm
-Del Sol Vtec (DOHC) 15mm
-94-00 Integra RS/LS 13mm
-94-00 Integra GSR 14mm
-97-00 Integra Type R (ITR) 22mm


everything writing should be given thanks to Moose. I didn't feel like typing it all for myself. Yes I am lazy but this is easier.

You might check the RSB info for the EG Si/EX. The size for the EX sounds right. As far as I know, the only hatch to get ANY sway bar was the Si, and it was front only (21mm). :)

Great info!!!

Also, the 90-91 EX is different from the rest of the EG's and DCs. It's pretty much a regular CRX/Civic knuckle but with the brake mounted further outwards(I am running 90-91 EX's on my 88 STD btw). Some guy ran 96-spec ITR knuckles on a CRX and had to slam his car to get zero camber.

The 90-93 Integra rear trailing arms have a larger diameter trailing arm bushing than the rest of the rear disk equipped cars. This isn't a problem usually until its time to replace the bushing...you have to know which one you have.


i was actually just going to post a question regarding the front UCA. I have a 91 Si...is the front UCA the same as a 92 and up? I'm asking because I'd like to buy the following:



and it is listed for 92 and up. If the 88-91 UCA are the same I can use it.

My 1991 Civic Si came with a rear sway bar and obviously LCA with sway bar mounting points.

Another question...what is the length of the rear LCA from year to year...or are they all the same?

semi-dumb question

I'm bolting on a rear sway bar from an 89 crx si onto my 89 dx hatch. I've already got the lcas, all the brackets and end links. My chassis has the holes for the mounting brackets, but no captive nuts. (ok, now for the question)

How do I get the captive nuts into the chassis? Where can I get the captive nuts I'll need?

Thanks. I wasn't sure if I could get into the chassis rail via removal of the bumper, or I was gonna hafta cut the trunk floor.

Thanks again,

Jake

look on the briteside if you do the drilling in the rear. to plug the holes all you need to do is buy a several of rubber gommet.

Very tru. I'ma try to get this done this week sometime. I've got new springs/struts, and the lca(s) to install also, and figured it'd be a good time to do everything at once. :D

Thanks again.

I believe the 92 and up are too long. Revo or Rhino makes a adjustable UCA for 90-93 Integras and 88-91 Civics.

I'm pretty sure they are all the same length. The ones I have now came off an integra, and they're the same length as the stock ones.
