About a year ago I found that my HKS SSQV (first gen) was going bad. To replace it, I bought a Greddy RS BOV (new, but mad cheap!) while it was in the process of being discontinued. Unfortunately, it came from the factory with a small leak that causes issues under light throttle. When attempting to loosen the nut and tighten the bolt a little it turned out that it was also somewhat stripped from the factory, and with a few small turns of mine it became completely stripped. I'm not ready to swear off Greddy altogether yet because I understand that things happen. I know that some other people have experienced the same and similar experiences with their RS too. So I'm wondering if anyone has any good or bad experiences with their Type-RZ bov? I'm running a s15 sr w/ intake, full exhaust / elbow (oem manifold), increased boost to 12PSI on stock turbo, and some other minor stuff. I plan to get to, but not exceed around 330-350whp. Is there an optimal BOV for a stock-ish setup that performs any better than others? I'm just looking to get something I won't have to worry about next time so I don't waste more money.

tldr: My Greddy RS sucked. Is the RZ engineered better? And is there a "best" bov for a stockish sr setup with bolt-ons?

I've got a HKS second gen bov in silver for sale if you want it. PM for more details.

I'm not a big fan of greddy bov. HKS, Tial, and Sard are the ones I like. Greddy bov are good if you want to recirculate though.

the RS and RZ are pretty much the same. the diaphrams are the same size and the construction is basically the same. only difference really is the trumpet on the outlet.
