no cam just a stock l32 with 20k miles off a 06 GTP, i really would hate to cam it since the motors in the car and rockers would also be a ***** to do buts its doable when i install the intercooler. im really looking to get the most mpg while dailying and the most power when at the track. i know power and fuel millage don't go together. since im not familiar at all with these engine and how they respond from the looks of it u think 1.9 rollers rockers, good springs and intercooler and a 3.1 pulley would be a good set up? or are the rockers going to help me much or should i just invest that money in 42.5 lb injectors and go lower on boost? i have headers and a CAI already.
so an upgrade probably wouldn't hurt, but that will hurt gas milage.
You meant help gas mileage right?
300. Maybe. But your not coming close to, or passing that without rockers or a cam.
