I have a few questions.. the first should be a simple one... what is the stock turbo on an '87 GN... TA60?
The car was overboosting.. so I checked the boost control solenoid and it does not appear to be hooked up correctly.. or at all. Does anyone have a diagram from the service manual, etc. showing the correct way for it to be hooked up. The car was burying the boost gage when I got it... I have it just plumbed from the compressor housing to the actuator for safety sake, just on the actuator it is making about 10 psi, so safe for now.
Last question, how accurate is the stock tach? The car has 187,000 on it, when you stand on it.. the tach goes to 6000 and then shifts.. on the 1-2 shift and the 2-3 shft it never goes below redline on the stock tach... the car is obviously shifting and running though the next gear and then shifting.. is this a common problem...? Also when cruising in 4th it sits at about 4-4200, also seems high.. I know the obvious thing to do is to buy some sort of scanning software and check it, but I am not sure if I am keeping the car, etc.
TIA for the assistance.. this car is fun so far... I did ALL of the spring cleaning items on gnttype.org today....
