hi guys.. I'm a new owner of 240SX... I got big problem on my car, hope someone can help me out!
here is the problem.... my car is sawp with SR20DET with T28 BB turbo... car is running fine, but one day I took it out for a drive... then engine feel powerless... RPM rev soooo slow... and I get no boost.... no matter how high the rpm I rev.... no boost at all..
I checked intercooler pipes, no air leak...
I checked wastegate, it's good...
I took out intake pipe and sping the compress wheel.. it sping freely...
I checked spark plug gap, it gap at .28... (old spark plugs)

what do you guys think???
Should I take out all intercooler pipes check if anything stack inside??
PLZ!! someone help me!!
