It was my understanding that a pop-off valve and a waste gate were the best way. I DID learn something interesting the other day thought.... On my 91 turbo there is a vacuum pipe which comes out of the waste gate and goes to the side of the turbo casing. It has a T for another vacuum hose connection which goes to a solenoid in the stock installation. The engine guy tells me that if this vacuum hose is open to the ambiant pressure, then the wastegate will be open. If it's blocked, then the wastegate will close. All I have to do to control the wastegate is fit a valve to this hose. I wonder what Rusty and Todd are doing in this area.

I am still sitting on that fence between turbo or not to turbo. (I have some splinters in my butt cheeks from that fence). I was reading the installation and operation manual that came with my MicroTech electronic engine management system, and under "setting up" there is a section entitled BstCUT, which says "This feature prevents turbo engines from overboosting by cutting all fuel supply when bost pressure exceeds the limit set in theBSTcut screen, i.e: if you set this value to 10 psi, all fuel supply will be immediately shut off when boost is 11 psi or higher." Does this sound like a useful tool in installing and setting up a turbo on my 13b? Please don't flame me, as I know less about turbos than I know about understanding women. Does this mean I would not need a wastegate? Thanks in advance for your replies.
