For valvesprings, go with a 918 spring and be done. Use the stock valvetrain for the rest, except the pushrods. Trickflow are a good pushrod and are far cheaper then the exact same high dollar stuff. Leave the oil pump stock.
Buy the 75lb injectors through R/C. Better to go to big on the injectors for a turbo motor in a street car. They do not affect driveability at all untill you get to the 96+ range with low IMP. Use a Aeromotive A1000 pump and regulator, they are good for well over 1000 hp and are dirt cheap.
