Hi I was just wondering if I can get some input on what performance upgrade I should do next to build a NA car. I have the basic, intake, header, exhaust, fuel pressure regulator. What is the next item that I should go with? I heard from a friend, unorthodox crank pulley, but I'm not sure what that exactly does, any input is much appreciated.

 

if you plan to stay with the stock motor that i recommend some headwork with the most important piece beign an upgraded cam from gude. then you can upgrade tha valvetrain and chipped ecu which will allow you to take advatnge of the newfound power.

 

awesome info, thanx RexB16
