Plugging wastegate hole..

Hey guys, I'm calling on the experts here

I plan to install my wicked wheel, and 4" exhaust sometime mid-next week and was seriously considering gutting the exhaust backpressure valve and tapping the wastegate hole and placing a bolt in it to completely remove it. I would like to do all this at the same time, while I have the turbo out and would like to know if anyone has attempted this feat yet and has some tips they would like to share. Anyone else who has any good information on the subject is welcome to respond to. Thanks guys...

My opinion is it would be wasted effort on the wastegate, just running with the actuator unplugged and cranking down the control rod a bit will hold more boost than you can make. No need to disturb the exhaust housing.

I think the wheel and gutting the EBV are fine idea's. Remember to unplug the EBV's electrical connector to avoid that oil leak.

hey thanks for the response cookie, the reason i was considering plugging the waste gate hole is because i read that the wastegate can leak even if the line is unplugged on modded enginges, and i didn't like the sound of that. I guess i'll try tightening down the control rod first and see what happens. Is the EBV"s electrical connector the same one i've already unplugged to keep it from working or is there another one??

Yeah, it does. Usually right around 30 psi it will off seat on it's own. That's probably a good thing since you are well past the stock turbo's compressor map by then anyways.
