A buddy of mine and I just tracked my low boost (1.3-1.4 bar) down to a faulty wastegate frequency valve in my 91 200 TQ. I couldn't find one on the web - anyone know what one of these babys cost?

listed in thier last catalog for $57.48

Hmmm, maybe I have the same problem with my 87 5kt, I drove a 91 200T, and it seemed to have a lot more zip than my car. I attributed that to the age difference, and mileage of the two vehicles.

I thought 1.3 to 1.5 bar was normal.

However, you raise a question that I didn't even think to ask, where abouts on the car is this Wastegate Frequency Valve?

Do you have a part number also?

Thanks...

The MC-2 will feel different than your MC-1. Higher compression ratio with a smaller turbo, less lag, same power output, feels faster. The 3B engine has a LOT more zip than either. 1.3-1.5bar is normal for the 10vt, but Ssyco has a 20vt (3B).

but it is on the firewall next to the coil. It is used by the computer to vary the wastegate setting. Had mine give trouble once, but a high boost condition. I figured it was sticky, so I washed it out with WD-40 (you know, spray in the vaccum fittings, fingers over the fittings, then shake), after that it was good to go.

You may be thinking of the throttle potentiometer or the ISV - the wastegate frequency valve is right by the turbo bypass valve (next to the wastegate)near the grill - on the passenger sode of the car.

on the location of the WFV on a 10 valve turbo...

Yours is located differently because you have a 20 valve turbo...
