Hey

I have a GTST series 2 R33 and i want to change the BOV because its not loud enough for my liking! but i dont wanna get defected either.... is there anything that i can change it to to make it louder? or am i stuck wid the standered one? What have you guys and girls done? anything that is a direct swap over of the standered one?

Cheers

We are in SA, so yes, it is illegal to have one Adz.

You need a retune if you disconnect your stock BOV apparently to reconfigure your idle.

The Atmo one will go where your stock one is with a flange that migth have come with your BOV if it was specific to our car. I am getting an adaptor made up for my Blitz SS BOV to go where the stock one is cause I want something a bit stronger and stainless in the stock ones place.

You will find if you block your stock one up (Thread in DIY section) then you will notice the car will stall when you approach lights, in parking areas, etc etc. So the only thing that fixed this is a AFC or a ECU apparently.

And yes, under normal driving if you do it without a retune, you will notice some fully sik woosh woosh action. lol. :)

Yeh, like he said, you will need a retune, it might not be too bad (the stalling) as with my bov blocked off it would stall maybe once a day. Best bet if u don't want a bov but you want sound is to go a mesh pod. Go a DRIFT pod or similar, just make sure the element is pretty thin and it will be loud enough

you underestimate the stalling my friend... it is possible to happen ANYTIME you stop, if you dont have ur foot over accelerator as you brake your f**ked, trust me lol.

It'll hunt for AFR like a c**t, go up and down the revs like crazy then if u dont balance it out with the accelerator ur stuffed, can happen anywhere, even while you are moving downhill, put it in to nuetral to double clutch cause ur synchros are screwed then the car stalls as you are rolling at 70km/h...

you need a retune if you remove the stock bov, and then the new bov u get needs to be tuned too...

ADAM, a vent to atmo BOV is one that VENTS TO ATMOSPHERE, ie, has a little trumpet or filter or whatever is aftermarket these days are pretty much all vent to atmosphere, thats the valve that creates the phshhhhhhht noise. k thnx bye lol.

I have just removed a turbo smart vee port BOV from my stock ecu'd r33. Stalling ??? not once in the severals weeks i had it on there....

The only thing i noticed having a atmo BOV on my r33 was a little bit of back fire upon gear shifts sometimes.. Did not sound bad at all.

And the little puff of black (barely noticable) when boosting @ 10 psi and gear change..

The reason I removed it is cause i wasn't a big fan of the noise.

I don't quite understand.. I don't doubt whether it would or not, but WHY would and aftermarket bov make you stall on idle?

Also, is there many aftermarket bov's that give better performance but don't make more noise?

the smoke and backfire is from putting too much fuel into the system... the car computer reads a lot of air rushing along (before BOV) and when you put the pedal down, adds fuel to the mix... if all that air is out in the atmosphere, it takes a second for the right amount of air to get to the block... if its recirculating, then there is a lot of air in there already, ready to go into the block...

I don't quite understand.. I don't doubt whether it would or not, but WHY would and aftermarket bov make you stall on idle?

runs your car too rich and it stalls... Im not certain, but i think cars that are having this problem should go get a tune...

      Does RB25DE Neo lower intake work with RB25DET Neo Upper intake manifold?

      By R34_GT to Turbo · Posted

      Ok I get you. But isn’t the butterfly intake a headache with the +T?  see this is my plan so far but please advise me into the right direction.  Nistune Ecu, 1000cc Bosch injectors, TD05 or TD06 Kinugawa turbo using stock rb25det exhuast manifold, walbro fuel pump unsure of model I think it’s 450/460, spitfire coils and sparks to suit and a R35 MAF sensor and boost sensor.    I was thinking maybe do a cheap eBay plenum $400-500 or try find a stock det neo intake. I think I’d port match it so it’s getting the full capacity but open to advice please.  Thanks

      R32 GTS (RB20DE) Injectors Replacement

      The issue now is the 'fuel cut' while driving, and when it happend, it does not stall. This, I did not test the fuel pressure while driving as I cannot with a fuel pressure gauge. I do have Nistune logs, yes. I have also replaced the MAF Sensor.   Also related to the FPG Fuel Hanger – I just realized that I need a Deutsch Crimp Tool to crimp some cables for the FPG Fuel Hanger. Need to purchase additional cables as the kit only included 2, which are for the float. FPG has not responded to my emails so far since purchasing. I thought about taking it to someone and having it done professionally, but I am reluctant since everyone I took it to messed up in some way.

      The German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.

      R33 GTR running -9 with no tune

      By joshuaho96 · Posted

      Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.
