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?

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 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?

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

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 :)

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler

      Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?

      Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
