Hi all Skyline nutters,

I currently have a BOV plumb back on the car which seems to be leaking sometimes at idle (like the brass valve get stuck in slightly opened position) and sometimes on the way to full boost (seems to stutter randomly).

I was going to replace it with a HKS SSQ, but have elected to replace it with a GTR BOV

- how many others have tried this simple conversion successfully?

Currently running a GT3540R turbo at around 1.1bar, so needs to hold the pressure not only at full boost but also when driving around town.

Any feedback would be good. It seems logical that it would work effectly without having to spend the big bucks

Cheers :sorcerer:

I'm running a gtr bov succesfully. Straight bolt in - bolts onto plenum. For the larger outlet of the gtr bov (flows more), I just used the gtr rubber hose over the gtst hose with a hose clamp

r31nismoid - ash is running one with big power.

Gt-shortie is also running one with a highflowed vg30 turbo.

Gtr bovs are proven time and time again. In twin form on the rb26s, a lot of the crazy power gtrs are still running the pair.

GTR Bov (from gtr33), was a Direct bolt onto the std bov position (RB25)

BUT

The rubber return pipe for the plumbback into the intake WASn't a direct fit.

i tried pirtek and shopped around to find someone to make me a rubber hose without any success BUT for the mean time i just forced the bigger return rubber hose from gtr bov over the std rb25 rubber hose with additional clamps,..

cheers :)

How would two rb25 std bovs work? As im sure i have 3 or 4 of the mofos lying around in the workshop. Was considering changing from the atmo to two stds for plumback setup on the racecar.

Has anyone had any experience with them? Im thinking i would have to weld up that bleed off hole which they may have, i remember my old rb20 bov had one, not 100% if the 25 ones have em though.

yeah, rb25 bovs also have the bleed hole.

someone told me that if u put a pop rivet in the bleed hole of the stock BOV its better for it, but i cant remember why?

anyone know why he woulda said that?

Blocking that hole off is supposed to make boost response better and come on harder because it won't be escaping through it. Some guys just use hot glue to block it. I used duct tape.

does it "flutter" more with the hole blocked?

      Never ending fuel pump drama

      By Murray_Calavera · Posted

      So last night pulling away from the lights, I lost power for about 1 second. Bit weird, but I kept driving... 5 minutes later the pump completely dies. When I tried to start the car, the pump won't even prime.  I left the car for about an hour, tried to start it and it all appeared fine. Pump primed, car started, got the fuel pressure I should have.... Start driving home, 5 minutes later it dies again. I'm stuck in a shit spot this time going up hill with a car right behind me, so I just let the car continue to turn over while praying to the fuel pump gods. After about 2 minutes of turning the engine over, the fuel pump came back to life and I got home (only about another 5 min away).  So I've been digging around online, it seems like the 525 fuel pumps really don't like to be run at 100% all the time. I've found quite a few examples online of people killing their Walbro 525 pumps within about a year of usage when they are run without PWM.  So, my pump is an Aeroflow 525 (AF49-1057) and I've been running it at 100% without PWM. I'm thinking the Aeroflow 525 didn't like being run at 100% and has burnt itself up.  I really am sick of dealing with fuel pump issues, my current thoughts are -  1. Use a Walbro 450 and run it without PWM. It seems like these pumps hold up pretty well to being run at 100% all the time. I only make about 350kw and can't see me making any more power any time soon so this is probably a fine option.  2. Get a Walbro 525, run it with PWM. I know doing this will annoy me as I feel like with only 350kw, its extra expense that I don't "need" and I'll be thinking the whole time while setting it up that I should have gone with option 1. I know I'll be happy with this option when its setup and running, its only the initial setup frustration and cost as an issue.  3. Get a Walbro BKS1001 brushless pump. This is the fu*k it I'm already going PWM, might as well go full retard. This option just seems better in every way, with the only downside being cost. But I don't know much about this pump so I could be wrong.  Happy to get everyone's thoughts before I go digging around in the fuel tank again.

      Like loud exhausts? You could be a psychopath.

      By GTSBoy · Posted

      Actually, it is probably pretty legit. I mean, it's still woke feminazi bullshit academia, but you would have to agree that it is very likely that there would be a correlation between wanting a loud exhaust and scoring at the unpleasant end of the scales for dark triad personality traits. The fact that they found it didn't correlate with narcissism and only with psychopathy and sadism definitely shows that the loud exhaust thing is more of a "f**k you" than a "look at me", and I reckon that rings pretty close to most of the dickheads who take it to the extreme. Remember, this is correlation with tendency to be closer to one end of a personality trait scale than the other end. Of course someone who is at the literal opposite end of the psychopathy scale is going to be so considerate of others that they wouldn't even think about wanting to upset anyone with a loud exhaust. So the finding isn't that "you are a psychopath". Just that you score more towards that end of the scale than someone who doesn't like loud exhausts (on average, not necessarily even for specific individuals).

      Blitz ER34 at some point hopefully, should be allowed in Gr3 if they do.
