(Technical Discussion & Questions - by e-rock, started: 06-27-2023, last post: 2023-06-30 03:31:31 CEST)
Hello all,I’ve got an 87 GT that I’m planning on restoring after it has sat for a number of years. It was in great, if mostly stock, shape previously but now that it’s no longer a daily driver I want to spend a little more time and money on the engine. In addition to things like a high...

(Technical Discussion & Questions - by qwikgta, started: 09-12-2020, last post: 2020-09-16 03:03:37 CEST)
Looking for some help. Does anyone know if the 3xxx motors (GenIII) exhaust manifolds will fit on the 3.1 GenII heads. The GenIII mani's look like they would flow much better than the stock GenII manifolds. I think the GenIII heads have "D" shaped exhaust ports, vice the "O" round ones on the...

I've just had a stock 3.1 engine installed in my 86. The engine is rated at 140 HP, just like the Fiero 2.8. By all injector size calculators, it should be able to run on the Fiero injectors. I have had the injectors from my old 2.8 refurbished and had a failure on one of them upon startup. ...

I still have some parts left over from parting out my Fiero. In this post, I'll be listing a bunch of engine related stuff. My Fiero had a 3.4 V6, but these parts will also fit the 2.8 and 3.1 V6 with iron heads. All these parts are used but in good condition. But since they're used, I'm selling...

Guys, second tech post of the day, I'm on a roll. Disclaimer... my Fiero has been in storage for a decade, and it'll probably stay in storage for another decade.
