tabetha, i am told it has 4x4 steel block, or rs500 block he couldnt remember which, i am left to figure out which parts were changed and which werent during upgrade from 408hp to 480hp also had high comp pistons fitted instead of lows, something was done to the t4 turbo to bring down the power range a bit as full boost used to come in late on, now its more usable, my mate owned it but he was hand it in and do the work type of person rather than knowing what was done to it,
is there a way of identifying the block etc, it has 2wd thermostat housing but as for the water pump i dont know, i can remove pump and measure impeller depth?? would you know from that which one is fitted?
cheers
john
