Here is what Rod wants...I know him and his car.
He wants to have power across the board. This will be mainly for 1/4 mile drags. It will need to be a cam for turbo apps. The car will be getting a T3/T4 turbo with full intercooler, hard piping setup, intake, and etc.
He already has a cat delete pipe and a 2.5" ss catback. He has headers on the car now, but those are worthless for the turbo kit. The car also has a stage 2 cluch on it.
He is looking to get a 13 sec and lower car. When the turbo kit goes on it will have about 8 to 10 psi of boost to start. Then the head and motor will be built to suit higher boost levels later on.
I hope that will help you give him some advice.
