G'day guys,

I.ve just bought my first skyline. It's a 1992 r32.

It's got no engine mods at all, just a 3" cat back and is really quiet. I'm wondering if i take the plumb back pipe off the stock BOV an plug it off. And let the stock BOV vent to atmo will that cause any problems?

This is just temporary until i can get a decent BOV.

Your advise would be greatly appreciated.

Hey

It will not boost properly as the stock blow off valve leaks air into the plumb back pipe which then, as you would know , joins back in to the intake pipe

It recirculates the air to keep the car running smooth, prevent stalling and surging through gear changes and when RPM drops rapidly

For the stock blow off valve to function properly it needs to be plumbed back at all times, if you block the plumb back pipe and have the blow off valve vent to atmo you will be causing a leak, therefor the car won't run/boost as it should so probably not the best idea

You can block the blow off valve on the cross pipe, block the plumb back pipe and block the vacuume line, that will work but probably won't get the sound your after

    • Just had this happen to me too.  R32 GTR.   Also broke "just before going out onto the track" - someone up there is looking out for us... Very scary since I was about to do a narrow street course with zero run-off and curbs everywhere. Many people on here upgrading to billet uprights and R35 bearings?   Or buying new OEM knuckles?  I am not keen to replace with another s/h 30 year old fatigued part.
    • Top off with distilled water and see what happens. If you keep losing coolant then you know to start looking.
    • Nope.    Grab a varex and turn it down as you get close to home, win win? 
    • So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?
    • The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.
