See i disagree.
I have a mate with a R33 GTST and his running costs have been mad. Clutches, Coilpacks etc all very expensive
Dont get me wrong you get more car, but i dont agree that itll be miles faster, if faster at all.
A car for 2k will have coils already, brakes you dont worry about those.
2k for the car
1.8k for a forge
600 on a second hand TD04 kit
550 for emange supplied, fitted and mapped
