Guys after buying a trust style BOV recently from JJR i decided to fit her up and do my usual thing in posting the how to.

Here's the BOV i got witha universal adaptor (not needed)

Pic of the factory BOV with rubber pipe removed to the return line. It plumbs back to the intake, though i havnt bothered to plug it yet as im not aware of any reason it has to be.

Remove the factory BOV and you'll find a 1" hole approx into the manifold pipe note the extra vacuum line coz it could get in the way later. Mine went in fine though so its check twice cut once guys...

Overlay the factory BOV on some cardboard then the new one and trace the individual shapes in positions that will suit the layout without fouling the vac line or bolt heads etc. This way you make an adaptor plate that keeps the original stuff close at hand. Then take some 10mm alloy plate and drill, cut file and shave until its smooth and slick.

Here's mine before final filing of centre hole.

And after thats done fitted to BOV using supplied bolts.

Fit her back up with the gasket you took off the factory one and presto!

Run a new line from the manifold to the BOV (i used smaller Blue silicone line)

And enjoy the new toy...

You can see another part of why i aimed it away. Lines up with my vent in the CF hood nicely.

Defected no probs un bolt and return to stock instantly.

Thanks :P

If you want to line the BOV up with the factory recirc pipe (if you want to use it as a recirculating BOV), then you can drill and tap the factory crossover pipe. Obviously pull it off to do it

I did this with my Greddy Type RS rip off BOV before I went front facing plenum, worked a treat. Then if you want to go back to factory BOV, you can make/buy grub screws to screw into the crossover pipe (if you have drilled right through it). With some thread sealant you shouldnt have an issue

Not taking away from the original DIY, just an idea for people who want to go recirc. :)

Seriously, you cheaped out and bought a non genuine Greddy bov, then had to mod the crap out of it to fit. Why the hell didn't you just buy the bolt on Turbosmart Kompact plumb back for $170 and be done? Even grub screwing the bleed hole in the stock BOV would be smarter imo.

Plumb that sucker back or you will stall constantly, potentially causing an accident, not to mention the fouled spark plugs and black rear bar.

Was that aimed at me?

If so:

It was hardly 'mod the f**k out of it' by drilling and tapping 2 holes into the crossover pipe

it was recirculating

I only did it to check the BOV (which I was just borrowing at the time) worked fine.

I have a genuine RZ now, on custom cooler piping

I'm not sure what the bad reaction was for, It was merely another way to do it if you want to retain the recirc. It's not hard to drill and tap 2 holes in the crossover pipe..... I was just offering some advice

Not aimed at you Callan, Pete was duped into buying the crap bov and left it venting, then thought everyone should be doing it. He should have kept the stock one there, infact Nissan should have welded them in place imo.

My point was made today, as I sat behind an evo8 that flooded itself at the lights. As I was waiting for him to start it, I wondered if I would hear the all too familiar ssq noise, and I wasn't disappointed. :/

Modding your car for street cred and ruining it's drivability... I just don't get it.

All good, I was a bit confused but now that I re-read your original comment, it seems alot less aimed at me now lol, opps

Didn't even realise this was originally from 2009 lol. Thread revival and I got sucked into it. Thought someone would have done a DIY on this before

Alot of us have all been down the atmo BOV route with stock/MAF computer and once you see first hand how bad the car is with it, you dont keep it around for long :) We were all young and dumb once

    • My thinking is that if the O2 sensor is shot then your entire above described experience is pure placebo.
    • Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.
    • Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol  
    • -10 is plenty for running to an oil cooler. When you look at oil feeds, like power steering feeds, they're much smaller, and then just a larger hose size to move volume in less pressure. No need for -12. Even on the race cars, like Duncans, and endurance cars, most of them are all running -10 and everything works perfectly fine, temps are under control, and there's no restrictions.
    • Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go.
