I'm new to this forum and Nissan's. I tried to do leg work in the search area but probably didn't look in the right places. I'm going to check out a car my friend got for us to part out tonight and need to know how to tell what engine is in it. He didn't really check it out but saw great parts and started taking stuff off. Things I know from him are.... Engine sits sideways, DOHC, Black Top, Stock looking Greddy Turbo, Full NOS Set Up, & a Turbo Specialties Control Unit. From what I searched it sounds like a SR20 but I need to find out for sure before I sell stuff. I don't want anyone to buy something then be pissed I sold them something different. Or point me to where I need to look and I'll research more.
