Hey guys,

I did a quick search but couldn't really find anything that detailed what needs to be done to fit GTR bov's to my R34 GTT engine.

From what i understand, GTR's use a twin bov system, which means i would need to get some custom piping done. Basically i just wanted to know if anyone has done this before and what was involved, or if not, if someone knows what exactly would need to be done to fit them?

Cheers,

Martin

Oh, really? I thought they needed the twin setup to work properly? Although to be honest i don't understand why...

So you can just use one and they fit straight on to where the RB25 one was? Still sound the same as they do on a GTR? Sound isn't important, i just think they sound awesome, so if they sound the same then thats a bonus :blink:

the hose can be "made" to fit..

needs more lube and pushing

Are we still talking about the bov? :blink:

Lol, thanks guys, so i can use a single GTR bov and it is a straight bolt on replacement for the RB25 one, no modification needed?

What diameter piping does the GTR bov use compared to the RB25 bov, do you know? Don't have the new engine yet, so can't go measure for myself :)

Hey guys,

Just wondering if running a single GTR bov will produce the same sound as running the twin set up? I just absolutely love the sound of the GTR bov's, but if it's not gonna sound the same with a single bov then i want to try and get two working...

This is the sound i am after:

that 2nd youtube video is great but they arent stock bovs. the stock ones wont give flutter.

I've been told that's not actually flutter, it's the turbulence created by the air flowing from the two bov's into the single return pipe. My mates GTR sounds exactly like this and the bovs are definitely stock on his car

GTR BOV's will "teeter" off each other etc, however one will cleraly not do that on its own.

This is what a single will sound like if the BOV can't quite pas all the air (this was a single on mine, it was ok, tiny flutter)

Ok but that still sounds quite similar to the twin setup. I'm not really after the flutter effect, just the sound of the bov. Does your bov sound like that all the time, or just under heavy load?

Say i wanted to install the twin setup on my car, what would need to be done? Is it possible? How would it differ to the single setup?

Hi Guys, sorry to hijack the thread but are you using GTR bovs on RB25DET's just for noise or is there another purpose?

Will the standard RB25DET one handle 300rwkw?

MOST people don't use them just for the noise, rather the fact that they are a very very good bov and can handle a lot of boost. I personally love the sound of them, i think they are the best sounding bov you can get. So i'm going for the upgrade, but really want the sound as well seeing as they sound so good.

Whats wrong with your GTT bov? When does it max out power wise?

Honestly i wouldn't know, engine will only be going in next week sometime :P

Stock GTT bov would be more than capable for me at first, i will only be running 12psi when i first get it back. But once i get the new turbo i will be running 18psi+, so i would like the GTR bov to have the peace of mind handling that boost.

If you're not after the sound then really i wouldn't worry about upgrading unless you are having problems with your bov.

      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...
