If you want to get any respectable power from it, firstly you need to get hold of 2c turbo pistons, they have a gallery built into them that sloshes oil around, this is to cool the pistons from the heat brunt of the boosted charge. you cannot use any petrol engine piston - they will break apart within the first few hundred rpm from the massive compression ratio.
You need to then get hold of a turbo engine injection pump and its nozzles, (its the one with the spaceship on it) Get its original turbo while at it. Verify the pump does increase fuelling as the space ship is pressurized (test on bench, max pump rpm = 2250) You need the orignal oil cooler too, it bolts to the back of the engine - all 2C have those 2 holes given for the stainless steel sandwich cooler.
