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?

      Possible swap on R34 RB20DE NEO?

      By Kapr · Posted

      Hi. A little bit of an update. It maybe(hope not) looks like i would need a new tranny(it would be "maybe" a cheaper or better option anyway) So i need some info. I know i need a different propshaft(i can make custom one) LSD is not a problem cuz the engine will be still(for now) N/A RB20. So if i buy RB25DET NEO tranny...is there something else i need? I read something about push/pull type but i do not know if i need to "change" something or i can just plug n play onto my engine a go? Thanks for the advice

      Turn signal wiring question

      By OakvilleGTR · Posted

      Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..

      Lower A arm Skyline v35

      By sonicii · Posted

      The bushing has failed, not all that uncommon for a car of this age.  Any mechanic should be able to push in a new bushing for you, or you can probably buy the entire lower control arm, complete with bushes.

      Could you not use "thermal" spacers to give the clearance, like the ones I used between the blower and head? That raised the manifold height by around 10-15mm Albeit the ones I used were for cathedral ports, but I assume they have similar for rectangular ports????
