hi,
is there a possibility to swap the 2.8 engine for a 3.1 , 3.4 or 3.8 without modification (without removing or changing engine mounts etc?)

kind regards

I think the 3.4 is as simple as it gets. Not sure but I think you need to drill new holes for the starter mount.

the 3800SC is a bit more involved but bang for the buck, well worth it. Lots of documentation here and many people willing to help.

I've done both the 3.4 And the 3800SC. the 3.4 doesn't get any easier (pull out the 2.8 bolt in the 3.4) (except drilling the 2 holes for the starter), and can have more "seat of the pants" power. (Not like the 3800SC), But it is SOOO MUCH EASIER, and ALOT, ALOT Cheaper.
Got deep pockets ? (always cost twice what you "Figure") And a lot of Down time.
In the end, Yea, the 3800SC is great, but expensive (Even doing everything your self)

Swapping in a 3.4 from a 93-95 Camaro or Firebird is as easy as pulling your stock engine and putting it back in. Rodney's starter relocation jig is designed for the do-it-yourselfer. He's gone to great efforts to be sure it works for you.

Keep in mind that if your original engine isn't an 88, you will have to use a flywheel or flexplate from an 88 Fiero or from a 3.1 equipped car if you install a 3.4. The flywheel or flexplate should not have chunks of weights welded to its backside.

You can get a new 3.4 crate engine from several sources.

If you have a 3 speed automatic I would strongly suggest doing a 4T60 swap at the same time. Adds work to the swap but really improves the driveability of the car and gas mileage goes way up.
