I have a gtst r33 S2 and wanting to get a atmo BOV but dont know which one to go for since have heard about stalling issues. Car is pretty much stock engine and stock ecu besides exhust system. Which would be the best bov to get that wont cause stalling?

thanks

all atmospheric one will cause you to have stalling issues,

But if you wish to get a atmospheric venting one i would recomend the turbosmart Dual-port one. this is because you cau set the BOV to vent to atmosphere, be plumbed back, or it can do both at the same time.

stock is good, same as gtr bov

if you want aftermarket I could suggest a GFB Stealth-FX atmo/plumb-back (100% adjustable) bov, nice sound, no stalling issues on plumb back mode

full atmo isnt a good idea IMHO, at the least some sort of adjustable one to get the 'mixture" of atmo/plumb back correct

+1 For stock bov, or GTR one.

I have a GFB Stealth FX and atmo sounds great. Plumb back is also good, nice and fluttery. If you put it half way you can have a quieter atmo sound.

I had it on atmo for a while and never had an issue with stalling, it did feel weaker though like the intake feel was different.

Just keep the stock on, or get a GTR one, and replace the stock airbox with a pod.

An atmo is just going to give you the shits after a while anyway.

I cant see the point in spending money on a aftermarket BOV?? its a bit of money to drop for just a sound...

Spend the money on a frontmount intercooler!

ok, ive heard that some say if you adjust the BOV correctly that it will eliminate the stalling issue, is that true or is the dual port the only way? Quote

no matter what you do to adjust the BOV you will still have to stalling problem. i would recomend a dualport one, because if you do get sick of the sound that it makes you can very simply pull the trumpet off the BOV and cover the port with the backing plate.

Keep the stock BOV and replace your air box with an Air Pod.

A pod will give you the 'Choo' noise and only when the turbo is Spooling.

If you get an aftermarket BOV it will "AARRCCHOOO" even when you are not boosting = Wank Factor

Or save the cash and go for a front mount intercooler. You will be benefiting the car a lot better.

    • Just be warned that that turbo will not be a direct re-fit to the car. The exhaust housing is, of course, in the same place. It has to be - it's bolted to the exhaust manifold. So the dump will fit up. But the centre housing is not as long, so the comp housing will move backwards. This will affect both the turbo inlet and the outlet. There is fab work that needs to be done. Yes. it has one, it should have one. Paper gasket.
    • I only recently purchased the vehicle, it came with the flex setup but the current tune is e85 only, which is why im wanting to get the tune redone to enable a mixture.  First i need to get the exhaust redone tho. I was thinking of getting a varex muffler but it sems they dont fit well in the 33 (hang low because of the valve mechanism which sticks out on top) and generally dont sound good. So that leaves me with redoing the entire exhaust (more resonators and mufflers) so its not a menace when i come and go from home, and then have the aes dump valve somewhere along the line to really open it up. I was thinking of having it before the cat but after seeing how insanely loud it will be (on a vl turbo) im thinking of putting it more towards the rear of the car, after one of the resonators. 
    • At this point I'm just 'hoping' it's the turbo seals. I did speak to someone who said it's normal for these turbos to have a bit of axial play? Not gonna lie I've never checked a turbo for axial play before but you could hear it tapping a bit as I moved it back and forth. Surely that's too much? My theory is (could be completely wrong), bad axial play, worn bearings, bad seals, oil into dump/compressor side, burns in exhaust = blue smoke. On a timing belt related note, my crank pulley was missing that front plate that sits in front of the timing belt. It's that metal round plate. It did have the rear one, and the woodruff keys are in the crank which was nice. Can anyone confirm if the NEO det engine has a front plate, im sure it would to protect the front of the timing belt or something. Water pumps...the pump I got was an NPW (yes grill me if I should've got a genuine one lol). It has a smooth mating surface, kit came with a pretty pathetic looking paper gasket. Do I need to use any RTV or just trust the gasket will work because its a smooth mating surface? Cheers legends have a good Easter break!
    • Cheers man, I thought the same.   Bit of an update on it all. It was definitely blue smoke, not grey after all. It didn't really smell oily but it was blue after all. Also puffing just the smallest amount on idle with no throttle.   I ended up pulling the intake and exhaust off and there was around 3mm of axial play on the turbo shaft. So I figured we'll that's buggered and sent it off to get hi-flowed at hypergear. Haven't got it back yet.   I haven't compression tested it yet. Had a look in the cylinder and cylinder 1 spark plug, looked a bit sooty but not oily. Then I've just started doing my timing belt because it's age is unknown.
    • In that case it is probably stock. It lives in the navigator side footwell behind the plastic trim just in front of the a pillar.
