There aren't many choices. The 3.1 your car came with, a down-grade to an earlier 2.8, or a 3.4.

I'd pick the 3.4 if I were you. GM makes a crate engine, which may be more than you want to spend, but it's a good engine with warranty. Or, one from a 4th gen f-body. You'll have to change a few things from your current engine, like oil pan, I think. But, the boys on the V6 forum will have details (try a search for 3.4 on that forum).

 

KED85 also has a tech article available for reading. Should answer a lot of questions for you.

 

Would a 3.8 fit? They came in later 4thgen Camaros and Firebirds, and they had something like 200hp or something.

 

Doing a 4th gen 3.8 swap would be about as much trouble and expense as doing a V8 swap.

 

not really. I got my engine/tranny/pcm & harness for $200
200hp 225tq

Almost done, gimme about a month to fire it up ( may not have y-pipe yet though)

It's a good thing it had teh angled tb for clearance.

 

And I'm sure your experience is "typical", and you included all the expenses to get it running.

 

actually, it's aout the same as when I picked up the 3.4 to swap in. That engine cost me $210, but I also had a 12 hr roadtrip there & back to save $$$$ on shipping. Local enignes were $550 (typical going price for a used 3.4) As for others costs, they go w/any engine swap, even when I did a 400~400 swap in my 77 T/A,

 

Swap looks great. Any mods?
