hehe....well we got the spooling problem fixed, as well as the oil leaks. It's easy to overlook some very simple things when you work all day and night on the Z. The passenger side wastegate wasn't tightened up all the way (it was on and off the whole day). The gasket was blown apart so a new one had to be rigged up. Needless to say, the Z is spooling like mad. The clutch is still slipping a bit, but I can hit 15 psi in 5th gear at 3200 RPM. These turbos definitely spool faster than my modified stockers (~ to T25/T28). Now I just need to remedy the clutch slippage, install the AVC-R, and get to a dyno for some tuning.
