I got a problem with my rb20 when im changing down gears say from 3rd to 2nd in the space of time when my foot in on the clutch the car sometimes stalls, its like it doesnt catch the idle when its about 1000rpm between the gear change.

If someone could shed some light on it that would be great

Probably your Blow off valve, is it venting to atmosphere?

I had same problem, bought a Turbosmart Plumback and fixed the problem.

Then again, could be something different. Usually happened to me when slowing down to a complete stop anything above 70kms

I had the same prob with a gold gtst I brought with a top mount to4e but it would do it more often that your issue everytime stopping at the lights!!, tried \ by passed everything!! :

coils ,iac valve , vac leaks, fuel issues, ecu , pcv valve, no bov , new bov, timing , even setting idle to 1500rpm, air flow meter , checked cam belt ,correcting the tps helped ,

worked out it was : "reverberation " where the air flow meter was too close to the turbo I spaced it out with coiled induction pipe and problem solved I was planning on mounting air flow meter and pod where the stock cooler was for cold air intake and help with stalling issue , I didn't believe it could be the issue but it was.

my gtr with gt35 does it a lil bit but hardly ever, iac doesn't work would help mine map sensor would also fix it

if above is no the issue try check for vac leaks again and block off the pcv valve and the other pipe going to before the turbo, vent rockers to atmosphere, unplug idle valve and set idle manually to 1000-1200rpm to rule out a few possible faulty parts \ issues

      R34 GTR Seats / No longer reclining

      By bilbo117 · Posted

      Hi all, Long time since I've posted here. Looking for some advice on what I can remove to further identify the cause of my issues.  I can move the passenger seat forward and back but the knob used to adjust the seat angle is pretty much free spinning, there's very little resistance.  Removing the side cover I can see that the chain is intact but the shaft for the adjustment spins without the gear attached to it moving.  What's my next step for disassembly here? Is this a common fault? Just being a little cautious as I didn't want to start removing bolts for a spring to fly out or something equally as stupid.  Cheers

      Those above shitboxes, mediocre and above usually have a turbo strapped to them, hence the slightly higher octane is required.

      I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.
