Here's the issue- I want to swap my 2200 out of an 02 Sunfire for the 2.4L. I know it's possible, and I've read some of the back-posts around here, but most of them deal with earlier gens. Here's a couple of questions I still have after the search-

1- transmission. I have the Getrag 5 speed already. I have seen posts saying the entire tranny had to be swapped, but I'm wondering if anyone has tried to just change out the bell housing. I believe all the internals are the same, am I mistaken about that?

2- alternator. No one has mentioned the accesories that I saw. I assume that at least some of these would be different (ie. alternator, starter, etc.), since it's a larger motor, but I'd like to know for sure what all (in that department) is going to need to change.

3- wiring harness. I read one post that said as long as the ECU is swapped, the connectors should be plug-and-play (assuming the new motor is within a few years of the old one). Am I looking at re-wiring everything through the firewall, or is that middle section gonna work?

Those are my basic questions, I may think of some more later. I appreciate any input.

as far as i know, you don't need a different harness. just the PCM. and as far as i know the accessories are the same too.




I was a retard, and now I'm permanently banned.

Thanks for the info, man. How about the tranny? Any advice there?
