FFS, my RB20 does not like stock bovs and I've got no fking idea whats causing it :dry:

It struggles to get to .4 bar at full throttle. With the bov blocked it makes .8 no worries. Also of interest is that the bov doesn't open properly when it's plumbed in. Opens briefly at full throttle but still flutters like mad otherwise, like it's not even opening. My old 32 would NEVER flutter with the bov plumbed in, like it opened even backing off at 0 boost.

On the plus side it seems pretty controllable to slide, even on stock sus with a weak viscous diff :P

could be a leak on your BOV by the sounds of things andrew....

try another stock BOV if you can get your hands on it mate..

Thats what I thought, so I did just that and it does the same thing :dry:

Stock RB20 one does it and stock RB25 s2 that I just bought does it as well. I'm thinking maybe a vac line somewhere might be a bit suspect.

i would say that if its making the right boost when the BOV is blocked off then just leave it blocked off....Flutter FTMFW

but now it sounds like the vac line from the BOV to the plennum is leaking or something strange is happening

let us know when you find out what the problem was mate

good luck

PS flutters man leave it fluttering lol

Not real keen on the flutter hey :P

Well, not all the time. Sometimes it's good (like driving through Mt Barker around 3:30 on a school day :P ) but yeah mostly it's just annoying.

What are you doing near a school andrew....specially on a school day :dry::P

    • Yes, it's similar length. 
    • Is the CD009 similar length from bell to shifter?    car will just be for the street with the odd track day. It’s RB30det, and weighs about 1000kg
    • The r34 gearbox is like $3400/3700 landed from Japan sometime last year.   Contact jessestreeter.com for info and quotes. From memory the navara gearbox needs input shaft machined down as I looked into a while back and there's a thread somewhere here from 2018-2021 about it. Depends on what your doing with the car maybe worth the dollars to go cd009 or a 8hp50/70.
    • VCAM doesn't really increase peak power, it just widens the powerband. So if you were giving up power with adjustable cam gears to get better low-end response yes in theory it "increases power" but otherwise not really. Stroker kit might put you in a more efficient region of the compressor map which will get you more power but at say 7000 rpm I'm not sure that much will change. The original HKS GT2530, -5s, and GTX2860R gen 2 are all roughly the same kind of turbo. If you want 600 horsepower those are the turbos you need. So 500 whp. Just expect to spend some quality time trying to figure out intake/exhaust piping. The "twin turbo" pipe is an obvious place to start. Make sure the actuator preload and all of that fun boring stuff is set up correctly. Throw a VCAM step 2 at it if you want good response, 2.8L stroker too. If you're not actually wedded to 500 whp all the time you can barely get there with -7s or Nismo R3 turbos, you just have to run E85 or race gas and run them hard:
