Gtr Bov On Gts-t

[abcent]

I just purchased a second hand single GTR BOV for my RB25DET as I want to retain a plumback bov that can cope with high boost levels. Will it bolt straight up to where the old one is? or will I have to get a new pipe made up? anyone done this before?

cheers

the gtr twins are located after the front mount but before the plenum.

im not sure how they are attached to the fmic piping. they are near the water bottle washer. i dont think it would be a direct swap and would need an adapter plate to mate it up. what problem did u have with the stock one?

[abcent]

dont think the spring is strong enough, i get flutter...

[RB SANDY]

the std ones start leeking at 12psi up.

[paulr33]

how cool

what do you mean

[paulr33]

if you block off the stock bov does the surge when coming on boost go away?

are u sure the bov is at fault? it could be compressor surgeing

[abcent]

only does it on high boost (18psi) on low (9psi) it doesnt do it. I'd certaily hope its not the turbo since its only about 1-1.5yrs old an only travelled around 4-5000km.

an it doesnt flutter when boosting, only on gear changes

[paulr33]

oh. my bad. i though it was during boost building. yeah the look at how u cann adapt the gtr bov. try here http://www.skylinesaustralia.com/forums/in...howtopic=126240

if that fails, you should have a look at the GFB Hybrid bov. it's able to be fully plumbed back, and has quite a bit of spring adjustment. Contact Brett Turner at Go Fast Bits. He'll sort you out.

a single gtr bov should be a bolt on to the standard gtst bov

[AlexCim]

my stock BOV wasnt enough and i fluttered heaps with the highflow on (1bar).

with the stocko back on i get that gay r33 stock BOV noise.

wasn't that just because the GCG highflows had bad surge problems?

A stock gtr bov will bolt on...i've got one on my car...only thing is u need a larger diameter plumback hose as the gtr one is considerably larger...

any idea what diameter? an what sort of length hose am I in need of? any pics of your set-up (how you've changed the hose)?

glad to hear it'll just bolt on.

everyone keeps saying turbo surge......the flutter is only when changing gear...ie not on boost...ie when the BOV opens an due to not strong enough spring in there its bouncing.....fastly open/closing.....fluttering.....so how can this be a turbo problem?

[abcent]

well yes, it bolts straight up, used the top radiator hose from Telstar TX5 (cut a small straight section from it) to plumback to standard pipe (as the GTR outlet is a bigger diameter). using the old pipe I cut about a 3cm lenght of it off an put it in the other end of the telstar rad pipe as a reducer onto the stock plumback steel pipe.

but I still have the flutter , an now if my timing of getting my foot off the accelerator when clutch goes in isnt perfect, I get a touch of VL turbo full sik dose pipe noise. strange...I thought the GTR bov would be better than the standard item...its pretty much the same.

luckily it only cost me $40 or id be pretty un-impressed, but now I guess i do get to add "GTR BOV" to the modifcation list of my car....lol

Correct me if im wrong but are'nt GTR bovs just 2 RB20det/RB25det ones?? They look the same on the outside. Do they have stiffer springs?? all these Questions

[abcent]

they have stiffer springs, the outlet pipe is bigger diameter an so is the diameter of the BOV inlet hole (part that bolts to pipe)

an if you sit them side by side...they dont look the same (RB20/25 BOV's made by Mitsubishi, GTR BOV's Made by nissan)

weird man.

I never once had an issue with my single GTR BOV.

It let off perfectly every single time... But then, Race Pace was where it was fitted... highly likely that was some sneaky change/mod to it

[abcent]

it is second hand, might be worn out? doubt it, but guess its possible
