I'm going to build my spare d16, i was running the gredy 50 state legal kit on it and the motor just wouldn't pass smog anyonemore so I rebuilt my other engine i had lying around. But I want to build the other one for some pretty crazy boost and power. My goal is around 350 hp. Does anyone have any experience with building the d16z6? I want to do porting and polishing but how much is that going to improve a turboed motor. I already have greddy e-manage but want to buy an AEM ecu system that can plug into a laptop so you can tune it. Are there any websites out there that anyone knows of that can direct me as to what parts and who to buy from??
