Hey all,
I'm venting to atmosphere on an ~11psi SD tune, and the plastic BPV that came with the stillen kit has started dumping boost at ~5krpm and higher (~6psi). With the apparent failing of the Bosch(?), I'd like to move to a Tial QRJ BOV.

I'm a bit confused on what I need for this however, as I see a lot of info about the different ports types, 38mm vs 50mm, needing to weld a new flange on the charge pipe, etc.

Can someone with experience in these please guide me to what exactly is needed to mount one of these with the stillen(non-A2A) charge pipe? Am I overthinking this and just need 38mm V-band ports on both sides to use the same hoses as before?

Thanks in advance!
