Well I have an SRT4 Neon that has front and side damage, as well as a chevy cobalt SS SC, a G6 GXP w/3900 and many 3500 V6 and a bunch of 3800 L67 GTPs all with body damage. So I am kind of looking at what I want to put in the car. I just dont know yet what I want to do. Kind of leaning at using the G6 GXP w/3900.
My brother has an SRT 4 Neon that has a bigger intercooler and some other upgrades and is plenty fast. I think that would be a cool drivetrain to put into a Fiero. Plus it would be a one-of-a-kind car.
Are the neon motors all aluminum? That would not only give you a lot of HP, but significantly drop weight as well. I know nothing about Mopar computers, but make sure it will be an engine that you'll be able to get running in another car..
