Hey guys,

Planning an R33 gts-t build atm and am looking for some efficient bov solutions.

Alot of people praise the stock GTR twin BoVs for their performance.

I was wondering whether people run just a single GTR bov or use the twins on other engines (more so rb25dets).

Also, I was wondering if anyone had a sound clip of them. I searched all over youtube but the only videos I got are off gtr's running loud aftermarket bov's. People say they sound good and subtle, so has anyone got some audio. Perhaps a generous GTR owner could take a sound clip?

Any info would be great

Cheers

I dont mind the quieter bovs out there, but some are stupidly loud. GTR stock twins from what people say sound good but yeah if you or anyone can get some audio that would be mad.

On the other note, if anyone has ran them on an RB25DET did you run both or just one? I am planning on a basic stock internal rb25det / gt3076r / usual supporting mods to get to around 300rwkw.

Just keep in mind that aftermarket plenum wont pass a mechanical inspection, mine didn't and they are a nightmare to change over

And all aftermarket bovs do is attract attantion and get defected and better yet u save cash!

Hah. Plenum change to "neaten" then engine bay. The definition of a worthwhile modification.

It does make for less intercooler piping and instead of running piping across the rocker cover

But still expensive to do just for street car. I was reading that the r34 neo plenum was the reason it gave that motor much more bottom end torque over 33 rb25, so if he got one of them from a wrecker would be cheaper.

I also read that cheap plenums of ebay can cause the motor to seize, so just be careful

Amy more info on the causing motors to seize? :)

Hi guys,

Rather than start a thread on the same topic, I have searched and this is close as I found, i too have an RB25DET and a pair of GTR BOV's which are yet to be installed. I was hoping someone could post a pic of how they were mounted using a forward facing inlet manifold and plumbed back in to the intake pipe. The reason I bought them and want to use them is that the current bov works well when venting to atmo but doesnt seem to work when plumbed back. I just get a lot of flutter back through the turbo. The pipe that the current bov is mounted on will be eliminated, non standard pipe anyway, when the inlet manifold is installed.

Thanks in advance.

Well, given that the BOVs are installed in the intercooler cold pipe just in front of the driver's side front wheel....that should pretty much tell you where it makes sense to install them on a GTST with a FFP.

I don't know if I would use both though. If you install both, you then have to joint their outlets back up in order to take just one hose over to the inlet side, or you end up having to take 2 hoses over to the inlet side. There's plenty of high power RB25s running just one of these.

    • I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed
    • I hear that would involve some nice country road drives into the hills for Mark...
    • I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.  
    • Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
    • You can use your VIN to look up the factory part number somewhere like amayama, and then look to order new if necessary. https://www.amayama.com/en/genuine-catalogs/nissan Depending on price you might want to rebuild instead. @GTSBoy I had an interesting insight into US market parts when the Titan rear calipers were sticking. New calipers were dirt cheap, about 20% more than a rebuild kit....they are just considered throw away maintenance items
