its just a XR6 Turbo mate, MK1.... with a T56 conversion, brass button clutch, PWR Cooler, custom pipework (done by Scotts Rods, QLD), valve springs (ISAR - Thanks so much Ian.. very much appreciated), upgraded wastegate actuator, and 3 1/2 inch dump pipe and metal cat... dropping into a 3 inch muffler at the back to try keep it a bit quieter, Walbro fuel pump, and upgraded injectors. and 303rwkw at 10psi was really good, I am happy with the outcome, althought I want more... will be getting the 14psi tune soon... and hoping to push about 320rwkw...
