but they sit open at idle (sucking in air AFTER the afm) so you can't vent them directly to atmosphere (learnt that the hard way)... they suck air in at idle causing stalling and rough as guts idle.

mine had an adapter kit put on them from the previous owner in japan. they vent to atmo and cant suck in any air :cheers:

so you just wanted sound?

anyway,

shaqrx3 - factory bovs are probably the best setup you will get.

but if you must upgrade and want sound, the single greddy type R is fine. it is huge and it will flow more than you will ever make..

Let me know when you want to sell your stock ones.

yes they sit open at idle, which makes tunning a hell of alot easyer.

ask any one that tunes gtrs with AFM's. if you have bigger than stock turbos or BB turbos its hard to get the idle right with an aftermarked BOV.

i had that problem when i got the new turbos on mine, they couldnt get the idle right, because the BB turbos are still spinning damm quick after a bit of wide open throttle.

i also see it as helping the turbos as well, the plumb back system flows air after the intercooler back into the intake. so its breathing in cooler air :)

just my 2c anyway.

anyone know where i can get stockies? ive got blitz one and theyre huge...but then again the BOVs are placed where most cops wouldn't look

They pop up every now and then when rice.. err.. people replace the stockers with aftermarket ones. Just keep an eye on the forsale section.

True, but given the prices on NS (as low as $150 for a "hybrid" copy FMIC) I doubt there is going to be many used ones much lower on here :D

      RB20DE NEO smallbox clutch.

      yeah first and reverse is where you will find clutch release issues (whether hydraulic or mechanical) because the difference in revs required is the highest there; particularly changing down from 2nd to 1st when still moving. To be clearer though, it is possible that the clutch release bearing is the wrong height. This is less likely than a hydraulic issue but it is not unheard of when you are mixing and matching

      Replacing turbo water line - any recommendations or advice?

      By jtha7 · Posted

      Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!

      From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.

      Lock up the old for sale / wtb threads.

      That's all good, I thought I was missing some interesting feature! Maybe @PranK can double check if that is something that is meant to be operating or not.
