Hey guys,

As of yesterday my cars (R33 s2 gts-t) been making this really odd noise, it sounds like sticking a pen in a fan, it only happens under acceleration and mainly in 2nd gear either at 40kph or 60kph, like i said its a fairly loud buzzing pen/pencil in a fan noise...though it doesnt happen all the time, it was happening all this morning then this afternoon it didnt happen once, and its randomly happening tonight...

Any idea's? Also after i got my new exhaust (catback) put on my cars been smelling fairly bad, a mate told me new mufflers do smell bad for a while, is this true?

Cheers

I thougt that, but the noise comes from the front left hand side of the engine and no where else, very dumb founding! Well its going to the mechanics today to find/fix the leak hopefully the noise and figure out what that weird smell is, i just hope they don't charge me out of my now bankrupt arse.

Yeh new exhausts do smell, genereally all the paint or anti rust stuff sprayed on burns off or slowly cooks on. It generally goes away after a few days. If its been heavily coated on it can even smoke off. If its coming off your front/dump pipe it can give you the impression something is wrong when it starts coming out from under the bonnet ;)

note. if its a brand name exhaust thats coated with like a hpc or something it probably wont smoke as much if at all.

      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.
