NISMO or rising rate Fuel Pressure Regulator. Fuel Pressure gauge. Boost gauge. Oil Pressure gauge. Downpipe. Intercooler. Intercooler piping. Couplings. Coupling clamps. Oil feed AND return lines with an inline restrictor for a non-ball bearing turbo. WATER feed and return line. Don't want to run crazy rich and blow the motor. I'd feel that 12psi would be safe. You'd have plenty fun with that amount of power. It'd easily roast the tires andget you scooting. I'd watch the oil pressure. The factory oil pump is 130k miles old and could kick the bucket ANY second. It'll SOUND good til it chunks a rod at you.

Make sure you have no vacuum leaks! Thoroughly inspect every part of your car to make sure it's in tip-top running shape.

*Your factory MAFS will limit you to only making 250whp so plan no more unless you plan on using an N62 MAFS or similar.

*Your factory clutch will NOT last long. Clutch upgrade pretty much required. Running in 4th gear all day if you have 5th gear pop out could make your car overheat and high operating temperatures kill motors.

*Your factory transmission has a LIMITED SLIP DIFFERENTIAL :woot: ROAST THEM EVENLY!

No bro. Please research before installing this setup. Throw out (sell) that SAFC and get a real tuning program. Go on the NISTUNE site, they might be able to work with your ECU. If not, i have a redtop SR20DET ECU i am trying to sell. I know you can chip these and they make daughtboards for them. Dont forget a wideband to monitor AFRs. I mean you dont NEED IT if your not tuning it yourself, but its good insurance.

If you already installed these items and your car is running, you should post the end results and maybe even some numbers :yesnod
