Thread: L32 in 97 Coupe

title says it. iv got an 04 compg that the insurance company may be totalling out due to an accident and a buddy of mine has a 1997 coupe that i could swap my entire drivetrain into including the engine, trans, harness, pcm, suspension and ect you get the point. literally just take every piece of my compg and put it into a 97 coupe. now what my question is is if anyone has ever attempted this with success?????? should i also swap my gauge cluster and shifter???? any input is awesome unless you are telling me im wasting my time bc i know it cam be done but need some input if anything special needs to be done or an easy way to do it. also will my subframe from my compg be as easy as replacing the 97 coupe with it?????

Why the BCM also though. just curious bc i didnt think i would have to swap that too. if i have to though i will.

You'd be better off designing a car from the ground up basically.

Personally, I wouldn't throw that much money or time on it. The comp g and really all 04+ use an entirely different data protocol (CAN BUS not class 2 data mixed with UART) so NONE of the modules off the 97 will work at all. You would literally be taking every bit of wire and swapping it. You'd have enormous trouble getting small things like door locks, power windows, and everything else to line up and match. You would have to custom fabricate brackets for everything and every sensor would have to be custom routed.

You could easily swap the engine into the 97, just change tb and minor vac/pcv lines. You'd loose the shifter and gauges though. Front brakes, front and rear sway bar should be able to be swapped no problem.

The subframe should match up just fine. Same as the impalas which people swap all the time.

The only way this would be feasible is if you just wanted the most stripped down car imaginable and no power door locks or amenities of any kind. Otherwise this project will become your nightmare.

Again, can be done, but you'd be better off swapping the engine and upgrading performance as you go.

But doesnt the bcm only control your windows and locks and lights and interior yata yata? Ik i gotta swap the petal box also but that wiring all goes threw the pcm.

The 97 pcm can not control the 04+ trans. Why not just use the l32 engine and gen v blower and make things much easier on your self. You also never mentioned if the 97 coupe was a n/a or s/c car?
