You're confusing two things for one. You either swap your stock plumb back BOV for an ATMO one or you BLOCK the standard one. They generally both screw up your AFM readings resulting in backfire, stalling issues, idle issues.

I've blocked the stock BOV and the only thing I've noticed is that perhaps my fuel economy has gone down abit and that I get the occasional loud pop (backfire) on gearchanges. No stalling or idle issues.

ok well....im talking bout removing the std BOV and installing atmo one and blocking of that pipe....LOL no idea wats its called... i mean i swaped it over....car was fine for a bit...then the thing i used to block the pipe started leaking and then the car began stalling and shitting itself...

so i put std bov on again and yer fine....

so i dunno wat to do...i luv the sound of aftermarket bov though. atmo one that is

Ahh I understand, you fitted the BOV and blocked the recirculation pipe. Just make sure the bung used to block the pipe is on tight with a hose clamp. If you have problems regarding idle its most like your BOV is leaking.

Run a MAP sensor... no stalling or idle issues at all :happy:

Coke Cap = BAD - I had this in there for a day before I got the Turbosmart plug (billet) and it melted; I'm lucky that the temps did not get hot enough to turn it into a liquid and run down the recirc pipe.

IMO; if you must use DIY bungs, the end of a broom stick is better!

FLUTTER ON BRO....

waa? I don't know any one who has one with a BOV :) I meant any r32 model, btw.. All have the outlet on the inlet piping but all were blocked with rubber grommets.. Not to mention everything i've read on this site seems to suggest rb20's were BOV-less :woot:

Do you actually know anyone with an R32? The outlet on the inlet you speak of is actually the inlet for the plumback piping from the standard bov which is located on the standard crossover pipe..

Now I am questioning whether you can actually read at all :)

Beer Bottle Caps as Bungs FTW! Used two for a long time, no dramas. Also if you are smart, you put the question facing outward, then you have a little bit of trivia to keep you company each time you open the bonnet.

No, not kidding. Have pics of setup.

Well i know 3 people with them and all of the BOV outlets are bunged up (well the outlets from the plumb??). I thought r32 gts-t and below were all BOV-less.. I've never really looked into BOV's and consequently know very little (so no need to go hack). To me, in most respects, they appeared quite superfluous, but if 32 gts-t's have them from standard i'd be interested in putting one on. Any pics of this crossover pipe? Or of the positioning of the BOV?

      Weird compression after rebuild

      By dbm7 · Posted

      Yeah. air pressure leakdown test is where I would be headed next here, using one's ears to determine whether it's the valves or bores/rings leaking...

      By GTSBoy · Posted

      More likely you didn't bed the rings in correctly and have glazed the bores. Running with misfires on a fresh build is somewhat of a no-no. Surely no-one "smoke tests" the combustion chamber? That's what a leakdown test is for. Smoke testing is, um, a bit of a wank at best, and only really useful for external pipework.

      Attesa pump mount options / ideas? R32 gtr style.

      By GTSBoy · Posted

      Well, obviously that kit is not a relocation kit or anything other than just the original isolators and the like. I would suggest that it should be a matter of just bending up some flat bar to build a mount over the top of some other diff, with the flat bar held to the back of the diff by the rear hat bolts. A little welding, a little thinking about how to secure the front of this structure, maybe some different hoses in case you can't get it in just the right place.

      Can you mount the ATTESA pump in other locations?

      By GTSBoy · Posted

      Pay diff/trans workshop to do this.   Nope. Z32 turbo ran R230 with 6 bolt GTR style axles. All other Z32 were R200. Basically same same as other R32 stuff. All were a viscous waste of space.

      So, I'm not a diff swapsies specialist, but I am pretty sure the 300zx ran an R220 not and R200 like the C34 Stagea, so I think it is of no use to you. As you said, all you need to do is get the centre swapped in the diff you have, which might be best done by a diff specialist. The current centre is probably desirable to someone to track so an easy path might be to swap your mechanical centre for someone with a standard centre (which is a viscous LSD, and almost certainly won't have any limited left). The only thing you have to watch swapping R200 internals between diffs is that the number of splines on your car's stub axles has to match the donor car, or you need the centre+stub axles and make sure they have the same number and pattern of bolt holes as your rear axles.  You swap your current ratio onto the new centre so you don't have to worry about matching the front. Alternatively, centres like the Nismo pro are much gentler (and have adjustable "tightness") so you could buy on of those from somewhere like Jesse Streeter or Nengun (noting it may cost you 1234% extra in tariffs by the time it lands)
