Thanks guys for the replys. I have looked at gcg website, but they do not list a distributer in Melbourne. SLY 33 do you know what size wheels are used in the stage 2 upgrade? I have been to ATP and was quoted $1500 for a high flow turbo. The owner, Kyp was telling me his brother has a GTST, they high flowed the turbo, match ported the standard manifold, fitted a 3 inch exhaust, FMIC, fuel pump and reg, kept the standard injectors, a wolf 3D and got 200RWKW and pulled a flat 13 at calder park with street tyres at 107MPH. Looking at the MPH wolud that indicate a high 12 pass with good traction? As for a computer, l am tossing up between a Wolf 3D and Apexi Power FC. The Wolf is alot cheaper, but l have heard it cannot support bigger injectors, is this true?
