Hi all, just bought a r33 gtst and on the way home I started getting a idle surge hovers around 800-1200 almost stalls sometimes but will regain idle after a few seconds to a min.

Not sure if it has a aftermarket bov that is causing the problem.

Also a rubbery squeaking sound from behind timing cover. Could it be just a tensioner.

Has a gizmo boost controller too wtf how do you work it???

Ok pulled off the AAC valve and it was a bit covered in engine breather gunk.

Took the solinionds off it washed in diesel than cleaned with carby cleaner put back together installed, than went for a drive and it's sweet.

Purrs like a kitten all the time.

Noise behind timing cover has gone but I suspect it's a belt tensioner, geeeeeez $300 for a kit

Seen the gates racing one on eBay a lot cheaper are they a good kit for these engines.

Also noticed a very high pitch squeal from the turbo like a dog whistle, it's only on very light throttle every now and than. Sounds like and old bluebird CA18 turbo sound. Weirdest sounding turbo out there if you ever heard one.

Still hold boost but the pull is not consistent from mid to high revs, only very noticeable. But than again it's got 2 1/2 or 2 3/4 pipe than goes to the rear muffler and reduces to about 2 lol previous owner was defected. Will this all reduce high range power maybe a stupid question to ask.

93 R33 GTS-t do they only come with a tiny front mount?

No need for a racing (blue) belt unless youre pulling mass power, and theyre noisy. Just go genuine Nissan.

Should be a tiny side mount.

    • They are under bucket shims. Tomei provides a test shim kit and then any measurement of shim required. 
    • I always wondered how you were supposed to buy a set of 24 buckets and somehow magically have every single one of them yield exactly the desired clearance. I would have thought you'd need to assemble a cam with either 12 "sample" or "example" buckets of known top thickness (or a single such sample/example 12 times over!!) measure clearances at every valve, and then do the usual math to work out what the actual "shimness" of each bucket needed to be, before buying the required buckets to make up he thicknesses that you didn't have on hand.
    • I now seem to be limited in power due to my rev limit/hydraulic lifters in my built RB25. I'm looking into converting over to Tomei solid lifters. Question for anyone that has done the conversion. I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  I don't know where I got this idea, as so far I see no mention of this in any of the Tomei documentation. It just states I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!? There's no way it's that simple, I must be missing something? 
    • I couldn't agree more. I should have started from the get-go with a NEO or solid bucket conversion. I started looking into converting over to solid lifters yesterday.

    • BRUH, one of the biggest mistakes of my life..... and i've had plenty ;[)
