Thread: New Jersey GTP- Fiero

Hello out there!
Bought an 03 gtp for its motor to swap into my fiero, now I'm considering swapping in much more than just the motor.
I'll be lurking, and asking questions about wiring harness stuff mostly.

We are both doing the same thing. I have an 87 Fiero GT with the V6/ 5 speed. I’ve read about a lot of different things being done between the Northstar being put in (I really like the idea, just a lot of engine bay modifications having to be done. Not sure I want to do this just in case I want to reconfigure it back to stock.) and the GTP 3.8 supercharged version. It’s the easiest of the options I’ve been considering. I want 300hp at the wheels and started consider the 3.8 with twin turbos. I haven’t got the donor parts yet. I will start when I decide the route I’m going to take. Definitely swapping to a 6 speed though. What are you doing and how is there any insight you can give me. Like I said it have an 87 GT W/V6 and 5speed with 116K.

Glad to see fiero action on here! I'll be attempting an ls4 swap myself soon.

P.S. selliot is making nearly 600whp with one turbo. Two appropriately sized turbos would put you minimum WAAAYYY over your intended hp goals. Not to mention, Those getrag transmissions won't handle that kind of power for long at all. I'd stick to supercharged where only a few cheapo mods can reach your goals. That being said, it's your build so do what makes you happy! Just wanting to lay down expectations from experiences of myself and others here. Can't wait to see pictures!
