im having the same issue with my turbosmart type 3 plumb back ( dont have it on the car currently) ive cleaned it out so the piston slides nice but its only at higher revs when it will open at lower revs it simply doesnt open and i get flutters. have thought about buying a different rate spring to go into it to make it a bit easier for it to open. Im only running stock boost tho (9psi). interesting to see how this is fixed

yea it does flutter.....i rev it up to 4000rpm and it still flutters......not enuff boost on 12psi??? btw thanks for quick rep

sitting at idle isnt the best time to judge it. go for a drive rev it to about 4 or 5 and then see if it still flutters

real or fake hks one? have you loosened it to the lowest setting. make sure you dont over do it or you will screw up the bov. the screw should only come out about 1.5-2cms and then stop. if you keep going you will unwind it off from something on the inside then break it. was it working when you bought it or is this the first time you put it on? maybe you get ripped off and sold a broken/fake one.

the flutter is the sound of the turbo spinning backwards, sounds cool but its not awesome as it puts quite a bit of load on the compressor wheel and the shaft.

ROFL!!!!!!! :( Try blowing into a leaf blower, see what happens.

But i digress, lets not start that debate again.

Just loosen the screw on the BOV. If all else fails, put the stocker back on

Are you positive that you have loosened it and not tightened it mate....i ran a GFB Stealth FX for a while ages ago and on the hardest setting it would flutter but on the lowest setting it would just vent....so maybe try turning it the other way and see if that makes a difference....Flutter isnt all that bad

also i heard it was unhealthy for the car to flutter coz its going back to turbo or something....can someone confirm....

I have been running my stock turbo with the BOV blocked off....just for the flutter...car is running 12psi all day everyday for the last 2 years and making decent power 214.4rwkw on 12psi with the stock turbo and its a R33 S1 no issues whatsoever and it gets a thrashing as its a weekender

is it true that if u don't recirculate the excess pressure from Ur bov back into the system it can cause issues? i had a hks ssqv fitted to mine for a short amount of time but did int have the hose blocked, i found my car stalling etc, and when i took it off and replaced it with the stock one i found my car running very rich and miss firing alot untill the ecu reset y was that

      Clutch done also about a year ago got a DCS HD Single Plate. Basically done everything but touch the engine 🤣 But will definitely get a fuel pump and ECU, then start saving 🫡

      Fuel pump and clutch and ecu that’ll get you to about 230 or so kw, after that the sky’s the limit and the budget blows out faster then you can blink

      Should add all mods on the car are done in my ownership. The car was a 1 owner in Japan and I'm first owner in Aus.

      Thanks GTSBoy. Did BC's so not Japanese coilovers. I've already done all the other points you mentioned besides the seat, I like the factory seats and want to keep original look. Done all the fluids and comp tests etc and all consistent and clean. Well and truly used to the power and car as I've been driving it for a few years as it is now. Contemplating next steps mainly. Preference to remain twins too. @Murray_Calavera Paying for labour.

      Hmm. I don't think it is possible. As soon as you start, you will be on the hook for all the money. $5-10k is enough to make it fragile. Here's the list of things you need to do to make it nice, and driveable. If Japanese coilovers, get them measured and tested, then decide if you're keeping them or replacing them. If low rate springs, then consider big ARBs. If high rate springs, then probably leave stock ARBs. Either way, ad decent end links. Replace and/or upgrade all suspension bushes. That's LCAs front and rear, UCAs & traction arms at rear, caster rods at front. I highly recommend GKTech FUCAs, although the step to spherical joints is a step too far for some people. Rebuild brakes front and rear. This means making sure the calipers are healthy, discs are up to thickness, hoses are replaced with braided. Add good pads and fluid. Investigate wheel bearings all the way around, tie rod ends all the way around, upright bearings at the front, balljoints everywhere. Any of these that are still original are likely to be a bit wibbly nowadays. Bride or Recaro driver's seat, with fairly deep sides. Nice tyres. Street performance wheel alignment. Or track focused, if you're not going to use it on the road. Fluids everywhere if not known to be fresh. Now, learn to drive the car as hard as it will go, before trying to add any power. Save up big $$. $5k is the minimum cost for putting a decent ECU into it. A big single, with manifold, new exhaust, injectors, fuel system upgrade, ignition upgrade, triggering upgrade, etc, is >>$10k. None of that (except the ECU) is a good idea on an old RB. You really should put head studs in it, investigate engine health (compression and leak down, real oil pressure at revs, coolant condition, etc) before even considering adding power. There's nothing sadder than the "I added boost then it shat the bed" thread.
