I'm coming up for the 200,000km service on my R33 gtst and I've opted for the "gates racing" kit, which includes water pump,timing belt,bearings etc..

i thought id replace all the pulleys while I'm there and the question i have is.

Is it worth getting HKS or tomei timing gears ? and or has anyone had issues with these?

also has anyone had issues with these lightweight pulley sets on ebay for a/c idler pulleys? link below

cheers

Better to replace pulleys with new stock ones in my opinion if they are a problem. HKS/Tomei Cam Gears are fine and nice upgrade if you plan on actually using them by dialing in timing otherwise they serve no purpose except to look pretty and function the same as the stock ones.

I hate Ebay and like to buy from trusted sources which will ensure I receive quality products with no chance of replicas. If a pulley or cam gear fails because you bought from ebay you'll be in a bit of trouble.

The Gates Racing timing belt and pump kit is a good choice, just make sure it's genuine gates products. You might want to look at your Fan belts also while you are there.

And hopefully you still have vct so really you can only change one timing gear the other will need a special one for keeping vct, readup im sure there is something out there possibly but probably not worth the hassle...

How std is the car?

Ive been running alloy pulleys and had no probs...

Thanks guys I appriciate it.

Mods are exhaust / headers , front mount cooler & splitfire coilpacks with upgraded low mount turbo ,manifold & bigger injectors to come soon.

But I think I'll just replace the gears and pulleys with original parts for now.

Thanks for the advice

      Have you put an aftermarket oil pressure gauge on and verified your oil pressure?   Noise being on the block, on exhaust side, how high up the block does it seem to be? It could be the VCT system getting cranky, especially if it's mainly at idle, and when warm, as that'll be your lowest point for oil pressure. Could be showing that oil passages / VCT solenoid are blocking.

      Well, hydraulic lifters will get noisy if they are dirty/fouled in some way, and exactly how that manifests will depend on exactly what schmutz is where. There is a procedure on here somewhere for dismantling and soaking/cleaning them. Replacing them with new is about 50% of the work and about 5% of the money!

      Ticking Sound On Idle - Rb25

      By myrbgivesmeheadaches · Posted

      Thanks for the reply @GTSBoy this is is a hydraulic lifter engine. Yea right i did not realise the lifters were supposed to be compressible while installed. I could push them down but i had to lean almost my while body weight on them.  I have never heard of a lifter/ lifters ticking only at hot idle and getting worse the hotter it gets. I have owned a few jdm cars with noisy lifters. This noise is slightly more subtle, it is more of a sharp gentle metalic tic than the solid and more loud tapping I've heard on lifters. I have used a metal rod, alloy tube, hose and stethoscope and could not find the source of the tick. But it appears to be loudest on the actual engine block behind the exhaust cam gear and next to the oil filter. I had mate (40 year old mechanic) go over it with me and he couldn't find it either..  Could it be a cam seal issue of some sort?  Cheers

      This seems problematic and unlikely at the same time. Vanilla RB2Xs have hydraulic lifters. They do have "zero" clearance, but only when running with oil pressure inside them. When not running, you should be able to compress them and obtain heaps of clearance. RB26s and Neos have solid lifters. They should have ~0.3mm and ~0.5mm on the inlet and exhaust respectively. If they have zero clearance then bad things are happening. With nothing else being wrong, it would mean that the valves would be held slightly (ever so slightly) open when they are supposed to be closed and it should have all sorts of problems when running, caused by leakage in/out through the valves. Or, zero clearance can indicate severe valve seat recession. None of it is good. Have you used a piece of hose as a stethoscope to try to localise the noise?
