We just picked up a nissan 240 sx with a sr20det that has sputters. it will fire up and drive but lags crazy bad, great compression, fuel pressure is solid, has spark obviously. What could cause this???

My thoughts are a waste gate problem, fuel problem, or just a bad turbo....

Double check for vacuum leaks. Is there a lot of shaft play on the turbo?
