I have been searching like mad for the last 48 hours and haven't found a definitive answer. It's coming to D day for me to install all my parts on my newly acquired car.

I picked up the knuckles with rear LCA's with sway bar and end links as pictured below



I was putting new wheel bearings in my Civic knuckles any way and they are the same part numbers as Integra units (Timken 510030).

So, my question is can I use 1994 Integra GS-R calipers, brackets, rotors, hub assemblies on my 1992 Civic Si knuckles?

I ask this question because the Integra grew up in Chicago and the knuckles have an *** load of rust on them and I don't want to pay to have them blasted and powder coated and my Civic grew up in Sunny Southern California and Arizona and are about as mint as you can get them.

Thanks and best regards!

all i know ia that the caliper style is different between the two....the GSR calipers are a "floating" caliper where the civic ones you have are a one sided floater...other than that everything else should go together alright. hope i helped.

I am pretty sure you need to use the DC knuckles.

IIRC, the 92 si knuckles are the same as DX, CX with 9.5" rotors. I got a set of 10.2" with knuckles from a JDM EG2 delsol to put on my 92 EG Si, but was under the impression that you needed to swap the knuckles out to. Not sure what the difference is between the two, but after hours of research and questions asked and answered, I was told I could not reuse my 92 Si knuckles with bigger rotors, calipers.

Here is a link to the thread I started asking simliar question:

it'll all bolt on. just swap the calipers and rotors and you're done. just make sure you get pads for the GSR.

grandtheftlunchbox

Del Sol SI's have 9.5" rotors in the front, Civic SI's have the 10.3" rotors. that's why.

grandtheftlunchbox

all 92-00 calipers float the same way, the bracket is just a different design between the 9.5" and the 10.3" brakes, as well as a smaller caliper. FWIW, 10.3" calipers won't work on a 9.5" knuckle.

Wrong, sort of.
EG Si's didn't get the 10.2" brakes until 94, same time they got ABS.
I know because my 92 EG Si has 9.5" brakes upfront and no ABS.
And the EG2 delsol I got my 10.2" brakes from was a 92, B16A.
I don't know anything about the Del sol's brake size timeline, but wouldn't be surprised if it was the same.

grandtheftlunchbox

wow, i've never seen that, but okay. in that case, disregard what i said before haha. OP- check to see if your original brakes are 9.5" or 10.3" rotors. if they're the 10.3s, the caliper/rotor will bolt on, if not, you need the knuckles.

I need to correct myself a little bit,
92-93 Civic Si w/o ABS 9.5" rotors, w/abs 10.3" rotors
94-95 Civic Si regardles of abs 10.3" rotors

So OP, if your front's are 9.5" like mine, you will need to swap knuckles as well.

Kidnkorner

92-93 Si w/o ABS have the 9.5, I have a 92 Si.

I have read that the 94-01 Integra calipers and brackets physically bolt up and the hub assembly is what physically locates the rotor. The issue is the rotors clearance in relation to the caliper

I am just going to have to do it and post my findings.

By the way, I found all the info you guys are posting, just nothing relating to bolting on the guts of 94-01 Integra knuckles onto 92-92 Si knuckles.

The OE Honda/Acura wheel bearings have different part numbers, but Timken lists the same part numbers for both applications. I will be doing a whole write up comparing the hub assembly if I have success. If this is golden then tuners won't have to use the knuckles if the procure the hub assemblies in addition to the other aforementioned components.

This is just like when I was installing a JDM K series 5.06 final drive set with bearing into my old transmission, the bearings had different part numbers, 4.7 vs 5.06, there was no difference in the size of the two just the size and amount of ***** in the bearings were different.

The EX/Integra 10.3" knuckles are different than DX/CX/SI 92-93 9.5" knuckles. I noticed the difference between the two, I have both and looked at just swapping over the larger 10.3" rotors and calipers, but had no luck, so now I am going to swap over the whole knuckle/brake assembly.
Good luck with it, hopefully you find something that I did not when swapping over.
Would be nice to see a writeup, if this works out for you.

Kidnkorner

I just don't want to pay to have the Integra knuckles blasted and powder coated or buy another set.

By the way, does anyone know what the knuckles are made of? My guess is cast iron, they are super heavy. It would be pretty rad if someone made some aluminum units.

I may very well just swap the rusty ones in if it fails.

I just checked the P/N's through Honda/Acura
The EX w/ABS and All Interga's share the same exact P/N for knuckles
The CX/DX/SI all share the same P/N for knuckles, which is different than Integra/EX.

So I would say your going to need to swap over to the Integra knuckles.

I think they are cast as well.

Kidnkorner

The main difference I have seen so far are the provisions for ABS hardware, the dimensions and hardware locations are the same.

Also, My wheel database says that factory wheel offset for Integra is 42 and the Civic is 35 leading me to believe that the hub assembly is the key to making this all work.

I wonder about the RS knuckles, there was no ABS or it was optional.

tlarimer

RS knuckles show the same P/N for GSR/LS, But also shows an alternate P/N, I'm assuming that would be the Non ABS knuckles, but they are a different P/N than the Civic DX/CX/SI 92-93

Again, this would be intersting to see what you come up with as far as a write up.
I, on the other hand, am just going to swap my knuckles over, since the JDM knuckles I got are in better shape than the knuckles currently on my Si.

I have posted my findings to this.
