Yes Don and engatwork you are correct. With this modification boost is always on until it gets to approx 14 or where you adjust it and then it dumps.

sjh, I believe there is no overpressure switch on 92/93 models. Listed in job 09-0050

Finished the conversion this afternoon and the car has all the boost it can use. The ALDA I'm running has been gutted which, when the turbo was not building boost, made the car smoke on full throttle acceleration from standing start. I've got another ALDA that I'm going to try in it either this afternoon or tomorrow just to see what difference it makes. Now, with the turbo building up to 14 psi boost the car runs good. Shifts are kinda hard so I may tweek it a little to see if I can smooth them out some.

Check to make sure you didn't knock loose any vac connections. I did that and had an awfully harsh 2-3 and 3-4 shift.

After running it again with the boost gauge on it I think I will go back and add the spacer washers to the diaphragm attachment studs. When I installed it I had to compress the rod slightly to get it to fit on the wastegate actuator pin. It looks like this has the same effect as making the wastegate open a little later.

Without running an exhaust gas temperature indicator what boost pressure should you start to worry?
