Hello,

Wastegate is after the turbo. It diverts the air from the pressure side to the exhaust for overboost conditions such as limiting boost and between shifts among a couple others.

The wastegate needs to go before the turbo! It diverts exhaust gas away from the turbine to prevent overboosting during engine acceleration.

I believe Damon meant to say a "blow off valve or BOV" (not a wastegate) goes in the charge pipe to limit compressor surge when closing the throttle blades as can occur during shifts.

Here's a pic of a wastegate flange location on an import engine. Same concept on your car, somewhere before the turbine side of the turbo.




I was alittle confused there. I knew the bov was after the turbo. Should the BOV be close to the carb/throtle body or anywhere after the intercooler Thanks
