ok guys i need help.

full story, i have an r32 gtr and recently upgraded some parts including turbos..

so anyway at 1.2 bar im making 275kw at wheels, and was told i could make more but stock afm's and bov.s have maxed out

sjust purchased some atmo bee r bovs that bolt straight on,

so today i pulled my front bar off to replace old bovs with new and realised that my car hasnt even got any bovs, the pipe has been sealed and lines run back on themselves.. WTF? im confused and totally at a loss as what i should do?

after reading loads on here i dunno wether to just bolt the bovs on and it will be all good, or wat?

anyone know what the hell is going on and wi need to do?

i was under the impression that at high boost lvls i was leaking and that by putting these aftermarket ones on it would hold and makes boost fine..

Agreed, and its been shown over and over again. The AFMs were probably running out of resolution at 280kw though.

I'm not really sure what you are descibing for the BOVS...but if there is nothing there at all, and you paid for a pair of new ones (that you probably didnt need in the first place) is sounds like a pretty bad deal.

But maybe when you say its blocked off you just mean the return to the intake? Assuming the BOVs vent the air externally, none of the return piping will be required any more (and you car may stall when you return to idle from a good run)

what i was told by looking at it now is that its all been completely removed for perhaps a decent single bov, but then if they removed that and now there is nothing..

cos the ones i bought are atmo does that mean i can just cut the sealed pipe and join mine and re join the lines and away it goes?

cos i wot need the return line..

Attached. Someone posted it for me, now doing the same.

I've got 2 ssqv's, thought i couldn't run without recirculation due to fmic being in the way (where the original pipe ran behind - no room now)

Last time i asked, someone said you could put on the stock ones and then place air filters over the open hole of both BOV's.post-31555-1235211944_thumb.jpg

I have a new question about gtr bov's.

I bought 2 and installed 1 on my gtst, the second day of having it it started making some very strange noises on release.

Pulled it off and shook it and could here something rattling around inside of it.

So my question is do bov's eventually fail like everything else? Has anyone else had this problem? Is it still safe to drive?

thank you. that pic helps..

and yeh ive been looking at the diagram above..

im just tryin to figure out exactly what i need to re fit the atmo bovs ive got..

so i know i dont need return lines..

so i just bolt them on as per originals would, then connect the hoses and wella?

    • @Murray_Calavera  If I were an expert I wouldn't be in here looking for assistance.  I am extremely computer literate, have above average understanding on how things should be working and how they should tie together.  If I need to go to a professional tuner so be it, but I'd much rather learn and do things myself even if it means looking for some guidance along the way and blowing up a few engines. @GTSBoy  I was hoping it would be as simple as a large vacuum leak somewhere but I'm unable to find anything, all lines seem to be well capped or going where they need to be, and when removed there is vacuum felt on the tube.  It would be odd for the Haltech built in MAP to be faulty, the GTT tune I imported had it enabled from the start, I incorrectly assumed it was reading a signal from the stock MAP, but that doesn't exist.  After running a vacuum hose to the ECU the signal doesn't change more than 0.2 in either direction.   I'll probably upload a video of my settings tomorrow, as it stands I'm able to daily drive, but getting stuttering when giving it gas from idle, so pulling away from lights is a slow process of revving it up and feathering the clutch until its moving, then it will accelerate fine.  It sounds like I need to get to the bottom of the manifold pressure issue, but the ignition timing section is most intimidating to me and will probably let a pro do that part.  Tomorrow I'll try a different vacuum line to T off of, with any luck I selected one that was already bypassed during the DBW swap. @feartherb26  I do have +T in the works but wanted to wait until Spring to start with that swap since this is my good winter AWD vehicle.  When removing the butterfly, did it leave a bunch of holes in the manifold that you needed to plug?  I thought about removing it but assumed it would be a mess.   I notice no difference when capping the vacuum line to it or letting it do its thing.  This whole thing has convinced me to just get a forward facing manifold when the time comes though.
    • Update: tested my spark plugs that are supposed to be 5ohms with a 10% deviation and one gave me a 0 ohms reading and the rest were 3.9ohm<, so one bad and the others on their way out.
    • 9" wheels are a little too wide for a RWD 32. They can fit. People have put R33 GTR wheels on 32s for years and years. But they are a very tight squeeze. This has been known for about 30 years. As I said - there is no difference between a 17 and an 18 in terms of what will fit. The rolling diameter needs to stay about the same as stock - not very much larger. If you increase that, you will start to have problems. If you increae rolling diamater at the same time as yo increase width, you will have problems earlier. as 9" wheels are pushing the boundaries already, you would need to be careful with tyre choice. I would put 8.5s on the front of mine, but would expect problems with 9s.
    • post up screen shots of your injector tables
    • Diagnostic flow for a code 21 says check signal at the ECU pins, on a voltmeter of some kind it should read 0.1V at idle, 0.12V cranking, 0.15-0.25V at 2000 rpm. Check each coil such that +1, -3 is infinite or very high resistance, -3, +2 should do the same. (-1, +3), (+3, -2), (+1, -2), and (-1, +2) should all be somewhere between 0 ohms and high resistance. If you trace the path from the coil pin all the way back to the ECU in the diagram the resistance you measure at the coil vs connected to the harness should be pretty much the same.
