Gtst Bov And Gtr Bov ?

[suburban drifter]

hey im just wanting to know is there any difference between a gtst bov and a gtr one ??? i have heard that the gtr ones can hold more boost than the gtst one..if soo can you directly bolt a gtr stock bov onto a gtst ,thanks for replys

[Basti]

they hold more boost and they are less "leaky" in that they'll show positive boost (on the stock gauge) at less throttle than the gtst one. they bolt on but the recirc hose is a different diameter. the gtst one wont fit. you should be able to source a gtr one from a wreckers somewhere

cheers bro any figures on how much boost it can hold im looking at 17 psi >? thanks

Id like to know as well, i have a gtst bov and i run just under 1bar, also do you have a pic of your bov basti to show how you hooked yours up?

[Basti]

i've just got it bolted in the stock location. i couldnt stretch the gtst pipe to fit over the outlet so i found some radiator hose that did, and shoved my stock rubber pipe inside and clamped the lot as tight as i could. now cos the stock pipe(inside the rad hose) is sitting right up against the outlet of the bov, it vibrated every time it vents and makes a honking noise. very annoying but functionally its fine. i'll get a pic up in a bit

im trying to decide whether to by a proper plumb back or just put the gtst one in a vice.

so it bolts on fine and the small pipe fits on ok but the other fat pipe that goes stright to the centre of the bov is smaller ? so you put smaller radiator hose inside the old hose to make it tighter so it fitted is that right hahah..sorry dude just trying to get my head around it ..if you can post up some pics that would be awesome

I can clarify this:

I went from a GTST bov to a GTR bov as part of my RB30 conversion, what has been said is correct, the GTR bov rubber recirc hose is larger & the flanges are the same so it will bolt up. Buy some rad hose and your set.

If GTR BOV's can hold a setups of people i know over 600rwkw, 550rwkw, 550rwkw, 540rwkw - it'll be good enough for you

yerp im sold any one wanna sell me one hahah make me an offer

[zonbie]

Interesting information, thank-you Forum.

Question: At what pressure does the GTR bov begin to vent?

[R31Nismoid]

They leak @ idle as it is.

So soon as you back off, just like any other normal/factory BOV would.

Aftermarket ones dont due to higher spring rates etc generally

[zonbie]

Ok. Thanks 4 that.

lol hope this hepls. im still drunken.

[suburban drifter]

awwww got ya cheers for that man hahahah sweet little drawing ...is there a way of knowing that its not leaking through the radiator hose or would it be obvious cause you would get no boost ?

[Basti]

no idea. it works fine for me holding 10-11psi. but im sick of the honking sound i get when just hlding minimum positive boost so i am looking for a more permanent plumbback solution

[lukeybaby]

what kinda boost does the r32gtst hold up to. i have a hks gt2530 which i will soon be putting on my car aiming for 220rwkws with supporting mods off course, will my stock plumback do the job?

[bozodos]

When I had my stock GTS-T one venting to atmo before I blanked it off, at around 10psi you could notice it venting and it struggled to make any more boost (set to 17psi at the time)

[lukeybaby]

hmm interesting mine sits at 11-12 psi but tapers down to 10ish on high revs, could this be why?
