This maybe an odd question for this forum
I have a wrecked 90 Chevy Cavilier with a good 4 cyl and 5 spd trans
(Runs Great Still)
what Pontiacs will this combo fit into. Sunbird ?
Can I make it fit a 88-94 Grand Prix?

[Mr_GTO]

Sunbird Yes.
GP probably not.

Which Sunbird years interchange with the 1990 cavilier
Does the Grand Am use the same drivetrain
or
the Chevy Corsica/Barretta
Thanks

Same years Sunbird. Not sure about the other cars.

Sunbirds swap quite well with Cavvies, but be aware of trans differences. If you have a 1.8 or 2.0, the trans is different than the 2.2. As long as they are the same, as in auto to auto, then everything else hooks up. Unplug the harness from the Cavvie, and switch the computer too, and you are set. Grand Am is similar as well, but I would avoid the Quad 4's due to reliability issues. You can even go V6 if you want, from a Z24, or Skylark with the Buick V6. I had wanted to take a 3.8 and put in my old Sunbird, but never got around to it. The 3.3 is a little brother to the 3.8, all the mounts would work.

Thanks for the info
Ive got a 2.0 and 5 spd it looks like another cav or a sunbird are really my best options.
and I really want to keep the 5 spd (makes a little car a lot quicker and fun)
If I understand the wiring harness is the same between 2.0 and 2.2
I just need to switch the eng and computer?

It depends which 2.0 you have, there is one that looks list like the 2.2, then there is the overhead cammer, different beast altogether. If you have the overhead cam 2.0, you can't use it on the 2.2, the starter mounts on the firewall side vs. on the front side on the 2.2. Personally, I won't mess with the 2.0 any more. Too much of a pain to work on.
