the SR20DET has a stock BOV and wastegate, rite? If i want to put in a aftermarket BOV, do i need to remove the stock wastegate and stock BOV?

 

No you dont, all you need is to change the BOV. the wastegate will not need changing until you get a turbo in the ranges of t3/t4 hybrids. mmm big turbo.

 

Looks like someone needs to do some research on how a turbocharged system works. I'm not trying to talk ****, but they don't relate to each other. If you have questions, continue to ask, but try to do some hunting on turbo info.
