holy shit, did you do a search?

This topic is covered about 10 times day.

But To sum it up - You have an AFM. Put an Atmospheric BOV on there to try and sound cool and you won't because your car is stalling all the time.

Yeah this guy up here has the factory BOV and a Blitz bov at the same time, and stalls all the time and runs heaps rich, nice pops on gear changes :whistling:. He just wont believe me when i tell him get rid of the atmo bov. But the best part is, he reckons it gives him like 15rwkw having 2 bovs hahaha.

BTW sorry for the hijack

peace

a few vs about 5,000,000 that have problems

its pretty straight forward what happens. Your car runs like crap because a atmo BOV is not suited for cars that run a AFM.

Oh, and yeah, my comment about searching still stands, because there is 11 millions threads about this. They even have replies from people that claim to have it working properly!

yep, aftermarket management will let you run a vent to atmo bov...

stock ecu fuels for re-circ air from stock bov, when no air due to venting to atmo you get that shiz fart/pop from overfueling ie mega rich fuel into hot front + cat = pop, no cat = flames out of exhuast

according to what I have READ !!! ps my nfo is not 100% as i have not done it, i like re-circ due to coppers having an issue with compressed air release coming from something on 4 wheels or its too loud, which ever they choose to use. yes... both are absolute bullshit but meh.... game on

Nope - I'm running a Powerfc and it still does it.

Its not the ECU - Its the AFM that causes the problem.

It measures the air, the ECU puts in fuel to match, and then the BOV leaks it on idle. (because since the Plenum is on vacuum on idle, its enough to pull the BOV open a little bit) and yeah, air leak.

Hence the rough running.

Hey guys just thought I'd add my experience. . . '95 R33, had a Turbosmart vee port on it when I got the car, ran very rich & sluggish on gear changes, stalled on hill starts, rolling up to red lights etc. . . changed for a stock BOV and have not stalled it since ~ 4 months ago.

On the turbosmart website you can find instructions for PROPER adjustment of the BOV, which will help a bit.

Anyone wanna buy a Vee port? :)

Cheers

      RB20DE NEO smallbox clutch.

      By Kapr · Posted

      Hi...so a "development" here aswell The swap is "done" and car went "test drive" BUT it seems the clutch(maybe gearbox?) is a little bit sad? I bought this clutch kit https://justjap.com/products/xtreme-heavy-duty-organic-clutch-flywheel-kit-nissan-skyline-r31-r32-r33-push-type "Problem" is that the first gear is hard to put into and it seems that the clutch is not disengaged. It was not the problem with the old clutch...(or like sometime the first gear would not get as easy specialy when the fluid was cold) So? Can it be like...bad "install" or is the clutch wrong ((it should not have been) i done research to get the right one) Or is this "normal" with new clutch and needs to be break in?

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      Hey everyone, Wanted to pick some brains about this issue I'm having with rebuilding my 33 rack (PN is 49001-19U05). All of the tutorials/videos I've seen online are either R34 or S Chassis racks which seem to be pretty straightforward to disassemble but this process doesnt carry over to my rack. Few of the key differences that I've noted The pinion shaft on the other racks bolt on with 3 torx bolts: Whereas my rack bolts on with 2 allen head bolts: These changes are pretty inconsequential but the main difference is how you pull the actual rack out of the housing. The other skyline/s chassis racks can be taken out by tapping the rack out of the body with a socket and it just slides right out. I'm unable to do that with my rack because there's a hard stop at the end that doesn't let the seal/shaft be tapped out. Can also see a difference in the other end of the rack where mine has a notch that looks like you're able to use a big wrench to unthread 2 halves of the rack whereas the other racks are just kinda set in with a punch. My rack: Other racks: TLDR; Wanted to know if anyone has rebuilt this specific model of steering rack for the R33 and if there were any steps to getting it done easier or if I should just give this to a professional to get done. Sorry if this post is a bit messy, first one I've done.

      I would just put EBC back on the "I would not use their stuff" pile and move on.
