If you are getting the updated Perrin FMIC, the H34 will fit right on. Otherwise, you will need to buy the flange & find a place to weld it on for you. Also, if you plan on running a dual valve setup, I would recommend the H25 instead.

It will hold higher boost levels better, but it will do nothing for performance & very little for sound, if anything.

so the h34 wont be a direct fit where the stock bpv is?

Not without a silicone reducer hose like what Forge sells with their BOV. It's called H34 because it's 34mm & the stock MSP BPV is 19mm.

where can i get a hold of a silicone reducer hose?

I don't know about a sr hose, but here is quote directly from TurboXS and the H34 on an MSP:

"H-series BOV will work but you must use the H-Supra adaptor kit (it is
21mm hose adaptor to H fitting and comes with the necessary plugs."

i was using the 25 millimeter diverter valve from TurboXS but i had it on really ghetto and i can't seem to find a propper hose to get the setup correct. when i had it on it improved driving all around in the MSP, killed the turkey too. but then the blowoff wasn't as loud, i just wish i could find a piece of hose that was like 20mm on one side and 25 on the other.

how do other people get the 25mm bpv in place of their stocker?
