Are there some differences between the 90-91 and 92-93 model years that I should be aware of as I am scouring bone yards for parts for my car? More specifically, front suspension, oilpan subframe exhaust header area, and also general outside trim, door hardware, etc.
Usually there is a list of differences and fitment issues online somewhere for most older cars that are still popular like this one, so if someone can point me that would be great.
Im asking b/c I am pretty much giving up on ordering parts one or two pieces at a time. I was lucky to find a yard in a nice dry state that freighted me everything I needed to repair the front end, and most of the new parts I need have been bought or ordered. Now whats left is a bunch of smaller pieces, rusty suspension parts that need new bushings, etc. Mostly stuff that is dirt cheap IF I get it from one single car, or pull them myself, BUT - as it turns out, reasonably complete 92-93’s are more plentiful than 90-91.
there are some subtle differences between 90-91 & 92-93… biggest one is bumpers & head/tail lights from what I understand…
Also I believe 90-91 were ODB0 while 92-93 were ODB1. I could be off on that but I know the methods for checking a 90-91 for ECU trouble codes is different than for a 92-93. engine parts will be the same except for the wiring harness, ECU and Distributor for the most part.
otherwise suspension and other parts are the same.
anyone feel free to please correct me on anything I have mis-stated above as I only really know the 90-91 platform, I am just speaking more on what I have gathered in reading through different topics over the last several months while working n my GS…
Oh SPeaking of “GS” did ya get that emblem? Mailed it out a week ago.
[QUOTE=djzachtyler;2280023]Oh SPeaking of “GS” did ya get that emblem? Mailed it out a week ago.[/QUOTE]Not as of yesterday (Holiday mail, probably). How did you send it, or what am I looking for, like oversized envelope? I have a lot of small-ish parts arriving, and have not opened some pkgs yet. I did get the fancy foglight capsules from one of the other members here… those are no help with the suspension tho…
Seems like the aftermarket headers are different for the 92-93 (like DC), so I am a bit worried that could mean oilpan fitment, or some subframe/suspension differences that are not obvious to someone like me.

I agree bumpers front and rear, tail lights but not the headlights, and 90 91 OBD0 92 93 OBD1. Manifold is different and well as the Distrubtor…
sent it out in a regular white envelope with first class postage wrapped it in kleenex… it isn’t very big… about 2-2.5" x 1 " x 14"
probably stuck in holiday transit. I just hope the chrome plate on the logo stays intact. Didn’t think about holiday mail and the possbility of rougher than normal treatment…
Headers will be different because of O2 placement. It’s located near the bottom on the 92-93s. Front suspension should be the same between all years. The 92-93s also use different camshafts and engine management which I believe accounts for the extra 10 hp. I’m unsure however if the heads have different flow characteristics or if the camshafts are the biggest difference.
I wish 92-93s were more plentiful out here. Our local lots are packed with 90-91s.
The mirrors on the outside are different for 90-91 and 92-93, a hood for a 90 doesn’t have holes for a emblem but 91-93 do. Rear mudflaps are different between 90-91 and 92-93. Other then what was already said about this is all that is different on the outside

[QUOTE=rollinmyda;2280044]Headers will be different because of O2 placement. [/QUOTE]I DO see that when I look at the pics of the aftermarket headers now, so you are correct. I am wondering if that is the only difference, b/c I believe I saw some post about a header not clearing something, either on the subframe, or the oilpan, or something like that. I think I will compare a few part numbers this weekend and make sure.
It makes that much difference if the O2 sensor is a few inches more or less down stream (?)
The only difference is that 9091 are unpainted and 9293 are color matched
The only different mirrors come on RS models, they’re more square and don’t fold. They are basically the same mirrors that come on 88-91 civics, they have a little spring to let them flex but not fold
90 GS sedans do not have sun roofs where as 91-93 do. Thats my random non obvious fact.
90-91 sedan tails are different from 92-93
90-93 sedan all have the same rear bumper
everything on the front is the same between sedans and coupes as well (fenders, anything motor related, bumper, headlights, etc)
My contribution as far as sedans go. These were hard answers to find when I was doing my car
The point of asking the Q. the way I asked it was to save some time. If I wasted any bandwidth here, I apologize.
Fact is, reverse searches are difficult, because you have to pick a part, for example a piece of trim or a suspension piece, look up the cross reference for model years, and guess at related parts… (car-part is not so reliable for smaller pieces) The search engine s on a typical board/forum can’t do that because it is basically a keyword search. I plan to make my own list for parts I care about, but help from other people is always appreciated.
For example, one member here sent me an article which has a short paragraph on every transmission that potentially fits these cars. That was a HUGE help because researching that one transmission at a time would take me forever (if he is reading this, Thank You for that).
I do read related posts, and info posted in unified’s build thread, for example, is invaluable even if some of us are not aiming for 190 hp. (Personally I just want his paint job, whatever I end up with under the hood… )

91 gs and ls-s integras came with color matched mirrors
