i recently purchased a northstar out of an 02 cadillac siville. I also have a Turbonetics T4 62-01 turbo and i was wanting to add it to the northstar, but was wondering what internal mods to the motor need to be done cams,lifters, springs ect. I saw this website of a turbocharged fiero and was impessed http://www.fieroaddiction.com/turbonorthstar.html i also looked into http://www.chrfab.com/ for the internals of the engine. Being the car is so light i was told i didn't need a turbo with the northstar but i already have the turbo so why not. have any of you turboed a northstar and have any advice? For those who used the northstar were did you get your info on putting it in the fiero cradle? I also have the cradle out of the cadillac will that work in the fiero?
