I have a turbonetics stage III turbo with the mount on the turbine housing for the delta gate. That's where I have the delta gate mounted and that exits into a 3 inch Mease downpipe that is specifically made for that application. The downpipe blocks off the original wastegate hole. The problem I have now is when it's cold outside, and the motor makes some real power, the wastegate is too small to control boost. Boost climbs over 18 lbs with the delta gate opened all the way. With a xylene mix in the tank, it works fine, but 93 octane gets you over 5 degress kr before i can get a chance to lift. I bought a Tial wastegate to mount on the crossover now. I also think that the gate mounted on the crossover would be much more efficient. There's no reason to send that extra exhaust up thru that puny passenger side header only to go thru a wastegate and come back down the downpipe. That's my $.02 , Good, Jeff
