take you stock bov off and and on the bottom of it there is a hole that constantly leaks boost, ther were some discussions about blocking it up with a screw and filing it off. But other than that keep the stockie, less problems with stalling and less attention from piggies...oink oink.. :D

Thanx for the feed back guyz, and all the help.. I was also wondering how could i get the cooler sound happening in my car, the sound which is something like Vooooooooodduudududu, i hear em mostly on VL's.

BTW, inark as u said for the cruises, i would love to cum but most of the cruises here are in south western suburbs. im in northern suburbs and its prettie long way to get to the cruise meetings u have. if it was in city or somewhere close to the city, it would of been great!

bovs... why not get some LEDs?

blocking that hole... hmmm i dont know much about that kind of stuff but common sense tells me that if nissan put a hole to release boost pressure im sure they did it for a reason...

im running "14" psi at the moment.... it peaks to 14psi @ 4200rpm then drops almost instantly down to a steady 10.44 by 6000rpm.

now im no mechanic, nor am i performance expert... but im guessing if that pressure drop is eleviated by plugging this hole up... my stock turbo is going to give in.

can someone clear this up for me? someone that actually KNOWS not someone that is guessing or thinks.

That Vooooodudududud sound is your turbo backspinning. See when you close your throttle, your turbo is still spining creating excess compressed air in the intake manifold. Once this air cant compress anymore in the intake, it then the air moves backwards, (back through the intercooler, and out your airfilter.)while your turbo wheels are spinning backwards & forwards really quickly. thus creating that Vooooooouddududu sound :P

These noises sound f*%&n sick, and are relativley harmless on low boost (1BAR & under) but keep in mind nissan has provided the car factory with a BOV for a reason. Mainly to reduced turbo wear & provide Faster spool times between shifts/gears (because the turbo doesnt have to "re-spool" as much between shifts.

If i wear you (original person who wants to change BOV), i would purchase a more accurate "plumback" (You dont want attention from the cops, youl get enough just driving a skyline) BOV for further down the track like a G-ready. Stock BOV perform very average after the factory boost setting of 7-9 PSI as the spring tension on the factory BOV is set to open on 7-9PSI. Allthough it will still work after this setting you will find that boost will come on quicker with a aftermarket BOV (like gready) as it will not "leak" boost all the way to 15PSI. (unlike the factory, under 15PSI)

I've got an old Blitz.

Originaly had it venting to atmo (trumpet and all). Car ran fine.

Now its plumbed back. Car still running fine. No noticeable improvements, just a tiny bit quieter.

I suspect I have a VERY STIFF spring. Even at 1.4-1.5 bar the bov will open with a loud woooosh then flutter after the initial piston opening up.

      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...
