this is a good one....which of these is yours, do you happen to know the chassis you have? if not, almost EVERY junk yard, used parts place has a computer system for compatibility, if you call, tell them what you have, (not that they have one of those laying around), but can atleast answer for sure, yes or no, if they match.

The 1986 Fiero GT, model, came standard with the high-output, 140hp, 2.8-liter V- 6 and dual exhausts,, Major alterations arrived in 1988 when the Fiero's front and rear suspensions were substantially upgraded, all brake discs were vented and GT's V-6 engine received an internally balanced crankshaft for greater smoothness.

physically fits but after changing the intake manifold, fuel delivery system, exhaust manifolds & P.S. brackets.

John for future reference, no power steering. Power steering was made for front engine cars because the weight of the engine and trans made it a pain to steer. Lol auto zone lists a PS pump for these even though they never had PS.

Since the phoenix was a front drive car I would imagine there may be issues with the motor mounts. Probably better off with a camaro engine.

Actually since the fiero uses a FWD cradle and suspension in the rear and the engine is mounted transversely, the FWD engine will more likely have the correct engine mounts. As for swappability, if it is a vin "X" or vin "Z" phoenix from '82 or '83, it should work after making the changes already mentioned. The Fiero technically uses a unique version of the 2.8, hence a unique VIN of "9" for the engine. With any FWD 2.8, you will have to make basically the same changes. This is simply a packaging issue for the Fiero which requires the intake and exhaust manifolds and fuel delivery to be changed. And of course, there is no power steering on a Fiero so those will have to be removed.

I've seen the kits to drop a 350 directly into these so I was assuming the mounts were designed for a longitudinal engine. Learn stuff every day.
