include boring out the block prefferably going with higher grade pistons that are heat coated and bigger cams more powerful crank 750CC injectors metal head gaskets. engine manifold need to be coated for extreme heat I would go with HKS ball bearing turbos not sure which ones racing wastegates last you will need a good high grade clutch, tranny will need custom gears, new driveshaft rear axles and new LSD and if you haven't dissable HICAS that would be first priority oh yes roll cage Last would be the suspension which i am not goood at. thats all i got i make no garantees on the outcome
84 50TH and 91 300ZX Both turbocharged and ready to ride
