Ok from what you have all said it's just a std turbo, thats fine and will only handle max 12psi thats fine too, as i have the engine in a lc gtr torana. i took it to willowbank and shit the clutch and roll through for a 13.6 @101 so i know the car has a lot more in it as i stuffed the start and killed the clutch and was only running 8psi.
Current mods to engine are s1 pom cams std ecu 3" turbo back exhaust 100cel cat and free flow exhaust split fire coil packs and a 600x300x76 intercooler. soon to recive new clutch from extreme clutch part # kni25003-1r
From what i can make out the engine is out of a s3 as it had the red writing on the engine cover and the turbo has a metal twin blade comp wheel.
Dose anyone know who is the best to talk to about hi-flowing the turbo and fitting steel exhaust wheel.
