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

    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
    • Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed
    • Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
