I need some help please.

I was thinking about selling my R34 GTR V-spec, found a guy who said he would buy it, took it for a week test tour, and blew the engine on it. He then left town, and I can't find him.

Anyway, I had to take out the engine, swap cranckshaft, replace piston rods and pistons, install new turbos, and all gaskets. Etc.

After starting the car up, it idles on 2500rpm, the blow off valve seems to not be functioning, the sound which used to be there when I let go of the throttle is not there anymore.

I have no clue on where to start in the search to get the idle down or getting the resirculating valves to function again.

I took the car to a Nissan dealership, and they tried to adjust the idle using consult device, but it didn't work.

Well, I don't have a good answer to why I loaned him the car for a week... He was a friend of a friend who I trusted.

Throttle bodies?

Honestly I am no mechanic myself, but I'm pretty sure the guy who did the rebuild have checked things as such, his guess was an electric fault or error...

I know its the throttle bodies because i did it when i was a 2nd year apprentice. Cleaned the throttle bodies during my rb26 build. Started up at 2500rpm. Did everything to diagnose then worked out its the throttle bodies. When u clean them it removes the sealer and now they act as if u have the throttle slightly open

      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.
