Trying to find recomendations for a blow off valve then best place to get them. I like the sequential sound and turbo smart one too. I am gonna be running up to 26psi of boost on the turbo to 28psi when on the track.

I am using a innovative custom gt61 turbo.

I know this isn't what you want to hear. Imho, BOVs are shit.

Here is why. The factory BOV is a plumback. So when you get off the gas it shoots that air back into the intake. Now, with an atmo vented BOV, it just blows it out. This will make you loose boost for longer periods of time between gears or when you back off. Detremential to a car in the twisties. If you plan on going to the track, this isn't somthing you want.

Now if you have problems with it leaking at high boost, then get your spring changed.

Also, all kinds of people develop idle problems after they install their BOV. Not sure why that is but I'm sure some one around here does :)

Anyhow, if all your going for is sound, then hell. Pick the one you like the best :D

For that sort of boost level your going to be looking at a Trust Type R. Usually once you are apporaching that 2 bar of boost BOV are about at their limits of what they can tolerate.

The Type R is an atmospheric venting BOV.

Also are you required to run an external waste gate with that turbo? I've never heard of it.

U have never heard of it coz its a custom.
The stock GTR BOV's dont leak, guys in our club run close to 2 BAR without leakage so IMO I wouldnt change it at all.
If u do, just get aftermarket plumbacks. Will vent more boost and recirculate the air.

It does require an external wastegate. I am using an innovative progate wastegate. and the innovative gt61 turbo custom with diffrent compressor wheel.......
