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.

      Block bump. $400. As above cyl 6 needs bore or sleeve.

      I would think making the argument that the travel is limited by a spring flexing against a spring perch as "the same method". Later on in the document they do state that the spring can't bind on full bump travel and cannot come loose in full rebound travel as well. (which is all very sensible). The laws are actually pretty sensible and reasonable. It's just that the people who enforce and check them don't actually read them or know them accurately. "Oh, coilovers? Instant fail mate. Don't even need to look at it." - Guy who will be instantly reported by me. There is probably merit to people who do get defected for height also get defected for the suspension in that state that allows it. I did never consider the people who are complaining about coilovers being picked on are also running around at 50mm off the floor.

      Ethanol Content Sensor - Always at 11%?

      I think given SAU's knowledge of E85 we can strongly conclude that 10% ethanol in almost any situation is entirely fine. Almost all of the myths against E85 were overblown, let alone E10.

      From your link See bold text, is this referring to damper settings, if so that may a issue for "some" inspectors, I cannot see aftermarket coilovers having the evidence that "must be available that its functional performance is equivalent to the original" Maybe just remove the adjustment knows and hope for the best???? Meh 5.2 Suspension travel In all instances, modifications to a vehicle’s suspension must ensure the integrity of the system and not compromise the ride quality. At least two thirds of the original suspension travel should be maintained in both directions (rebound (i.e. extension) and bump (i.e. compression)), and rebound must be limited by the same method used by the vehicle manufacturer or if this is not practicable due to the nature of the modification, an equivalent method. If an alternative method is used, evidence must be available that its functional performance is equivalent to the original.

      They actually don't - They adhere to VSB14 rules just like Victoria. The rules are against CABIN adjustable height, and it quite clearly states that the height has to be within parameters. I asked the VASS engineer to confirm this when I got my car engineered and they refused to engineer the coilovers because they didn't meet the requirements for requiring engineering. (mine are height adjustable.) People "Not wanting to bother" with "Actually reading/knowing/adhering to the rules" should result in fines and immediately losing the ability to issue blue slips and/or RWC's in Vic.
