hey i just bought a 98 240sx turbo and im having some problems with it the things dont to it were a ams gt32 turbo 480cc injectors walbro 255 fuel pumps apex-i safc2 and n62 maf and a now name intercooler the idles rough it will go from 1000 to 500 and almost stall then back to 1000 again and when i get drive it the car reachs full boost around 3000 at like half throttle the car is good but breaks up after liek 5k and when you try to boost at wide open throttle the car starts to buck i was just wondering what the problem could be thank

Check timing, for boost leaks and you need to get it tuned!!! SAFC wont do crap for a turbo that big.

And check Sp too lol.

sounds like you bought someone elses problems....j/k

As was stated above, check for leaks and get a good tune. Thats the worst part about buying a built car from another person, you dont know exactly what they did

Good Luck

take it to a dyno, use a wideband, and have it tuned.... might cost a little bit but it will be worth it in the long run
