Year: 1990 - 300zx: 432 WHP/419 WTQ. Pretty much everything is upgraded except for the engine itself. I have not rebuilt that yet and this is probably why I am limited to 432 hp right now. The Sport 700 turbos are cabable of so much more than the stock engine can handle........I'm just running at a max safe power for now until the rebuild. I spent 2-years working on this one after my first '90 was stolen. I love Z's and will never sell this one!
