The guy I sold my old fiero to bolted a 350 to the banger autobox that was in it.

I wonder if a Camry v6 would slip in there or course there's a the North star option...

OK, I had to look that one up.

Nice rev limit, too bad it appears so very complex, never get it to run without the ECU and all the sensors. 

Wondering if the earlier 2.0 might be simpler?


They are based here in the UK, but it may be worth looking up "crapengineering" on Facebook regarding a potential Mazda KL swap

what you could do is keep the iron duke in the back until it pukes out and find a rear ended fwd v8 caddy, olds, etc with a northstar, 455, 500, etc, and chop it and the fiero in half and weld them together. or, if you like well handling cars, a 1st gen neon, civic, accord v6, or any other well mannered fwd car and do the same twin engine awd thing.

I’m a car nut by anyone’s standard and I normally would never suggest such a thing as I’m about to but I’d recommend lighting the fiero on fire and let it burn.  I’ve never been a fan of Pontiac's mid engined wonder.   I’m sorry and I feel really bad having just typed that.

I've got an Audi v8 and 5 speed I was going to stuff in a Fiero. The obvious answer is 3800sc or turbo. Cheap, easy, big power possible, and been done so many times there's all the resources you could need. Northstar is also a pretty good option, they're cheap and can be adapted to gm fwd manuals pretty easily. Same gm metric bellhousing. The 88 Fiero had better suspension but it wasn't really lotus at all. The earlier ones are actually better to modify because the 88 wheel bearings are unobtainium and there are suspension options to fix the bump steer issues in the early models.

How do you plan on shedding 1,000 pounds much less easily?  

Asking because I have a 1985 Fiero Notchback that I'm at a cross-roads on ....
