slamaa Posted July 2, 2012 Share Posted July 2, 2012 (edited) Hi, Just bought a R33 GTSt, I am upgrading the intercooler and piping and need to know what size bloe of valve adapter i need on the piping. What is the best BOV for a 33 gtst, 25mm, 32mm or 38mm? This is the kit for the cooler and piping. https://www.plazmaman.com/shop_itemdetail.php?itemid=142&cate=35 Cheers Edited July 2, 2012 by slamaa Link to comment https://www.sau.com.au/forums/topic/403888-bov-size/ Share on other sites More sharing options...
JustinP Posted July 2, 2012 Share Posted July 2, 2012 Triple 50mm BOV's, each feeding into a megaphone for additional street credibility and general awesomeness. No actually make that four BOV's, three isn't enough. Link to comment https://www.sau.com.au/forums/topic/403888-bov-size/#findComment-6426320 Share on other sites More sharing options...
Tai1or Made Posted July 2, 2012 Share Posted July 2, 2012 I've got a Tial 50mm Trial BOV that I want to get rid of. Just need 2 more. Link to comment https://www.sau.com.au/forums/topic/403888-bov-size/#findComment-6426324 Share on other sites More sharing options...
Dajae Posted July 2, 2012 Share Posted July 2, 2012 I heard that if you stagger the sizes (4 in total, each one smaller than the last) makes the best "zuuuuutututu" sound. Also helps free up about 150rwkw. Link to comment https://www.sau.com.au/forums/topic/403888-bov-size/#findComment-6426353 Share on other sites More sharing options...

R31Nismoid Posted July 2, 2012 Share Posted July 2, 2012 This is the advice Straight away it's turned to dirt. LOL. Buy a set of GTR items. Job done! Or use a single GTR BOV either/or is fine.

Dajae Posted July 2, 2012 Share Posted July 2, 2012 This is the advice Or use a single GTR BOV either/or is fine. +1. I used to run a GTR BOV when I first got my gts-t. I now run a Turbosmart dual port plumbed back... Apparently good for 40psi.. Which is good because I'm looking at running quite a bit out of a EFR eventually. When they get sorted, anyway >.< Link to comment https://www.sau.com.au/forums/topic/403888-bov-size/#findComment-6426462 Share on other sites More sharing options...
BLITZ-26 Posted July 2, 2012 Share Posted July 2, 2012 just leave the stock one on there..... there is no reason to change it Link to comment https://www.sau.com.au/forums/topic/403888-bov-size/#findComment-6426500 Share on other sites More sharing options...
34GeeTeeTee Posted July 2, 2012 Share Posted July 2, 2012 just leave the stock one on there..... there is no reason to change it Looks like my FFP piping kit, it was cheaper and easier to weld the adapter than it was to source the flange for the stock on, and my stock one leaked... So there is occasionally a reason to change them Mr no BOV man!! Link to comment https://www.sau.com.au/forums/topic/403888-bov-size/#findComment-6426790 Share on other sites More sharing options...
kosmo90 Posted July 2, 2012 Share Posted July 2, 2012 (edited) Just installed that kit, used a turbosmart 32mm recirc bov, it has a 38mm adapter. Plazmaman need to know this.

Dose Pipe Sutututu Posted July 3, 2012 Share Posted July 3, 2012 or run none and have this: (I have to stop reposting this LOL) Serious note, doesn't really matter if you're not smashing much boost down the motor, most if not all guys make about 300 or so use the stock one or nothing.
