must deffo have a 4wd head cos there aint nothing there mate, in fact most of the car is 4wd as it used to be one!!2wd when i bought it, the kid i bought it off was full of shit and i honestly dont have a clue why its now 2wd? i took it to jam sport and they changed the L8 FOR A L6 chipped that and changed wires over on TPS, SO I WONDER IF THIS COULD BE THE REASON FOR SOME OF THE PROBS LIKE THE TEMP GAUGE??
