Chssis swap, need opinions and suggestions!
I recently decided that my '91 chassis isnt worth building up, but all the parts on it are worth keeping. I can get my ex' gf's poorly running 88gxl for $500 with a straight rust free body, i want to swap just about everything into the S4.5 chassis from the '91, heres my issues questions and what not.
Both cars have 5 lug with vented rear rotors
Both cars have power windows,doorlocks and security
Both have rear wipers sunroofs etc.
BOTH NA!
Which wiring harnesses should i use?
the turnsignals and hazards (along with a few other electrical components on the 88 have gone AWOL.
i'm using a fresh built S5 engine and probably the trans too, arent the s4 and s5 tranny mounts different?
which body harness should i use?
stick with manual belts?
stick with s4 gauge cluster?
s4 or s5 ac system?
use doors from s5?
lots to consider
planning on stripping the 88 to a rolling chassis and re-painting it black (like the 91) then building it up
emissions issues form using a '91 engine and emissions system in an 88?
lots to think about . . . any tips would be great

Welcome to my world. Personally I would say go for it but you'll need patience and time. It's been one month since i started my teardown/swap/rebuild/resurection and i just finnished the disassembly. A good body is a wonderful thing to have on a seven and down the road it will pay off but then again thats just my $0.02

Yeah, i think i'm keeping the S4 body harness, but i'm definetly using the S5 engine harness and ECU, i think im sticking with manual belts and s4 guage cluster, since s5 has been known to be much more inaccurate.

Still need some answers on this
i'm going to huse the s5 engine, transmission, harness and ECU will the s5 ecu be compatible with the body harness on the s4.
Still dont know if s4 and s5 n/a transmission mounts are the same or not . . .

S4 and S5 crossmembers are different. Just get the appropriate one and you'll be good.
