i know i sound like a knob but the car already has the ls1 in it and the car is cheap. Ive been traking my GTR for 3 years, going to track day events, now i want to start getting into some competition events. Alot of the cars i have been around, many of the issues are to do with the turbo/intercooler/boost. so my thinking is the less you have, the more reliable its going to be. When i say cheap its all realative i guess. looking around the 10-20 grand.
