25 Ex Cam Pulley , What Locks Up Best And Doesn't Move ?

[discopotato03]

Been researching RB adjustable exhaust cam pulleys so as not to be beaten around the head by the please search brigade .

Needs facts on more vs less (5 vs 3) clamp bolts and mainly what just works reliably .

Don't give a rats how pretty because not buying to look at .

Based on 5 bolts the Tomei looks the goods but mass wise the 3 bolt HKS seems popular .

It would be good to know of a safe pulley to use that also had accurate graduations because I hear some brands are not accurate .

Just the facts please , chears Adrian .

I have had two cheap Chinese no name cam gears and both were fine. I was advised to replace the bolts with better ones but the engineering supplies shop said they were already of a high quality. Once you have finished tuning you can loktite them if you are nervous. Sometimes the gradations are back to front but that shouldn't be a problem if you know what you are doing. The actual markings seem perfectly ok but in any case all the tuner is really doing is turning a little one way then the other till the dyno gives the answer. In short I see no reason to buy a $350 gear instead of a $70 one.

What he said ^^^

Always loktite when finished, and dont overtighten the bolts

I would prefer something supposedly Japanese made because I lack faith in things made on the cheap . The Tomei at ~ $200 is looking good ATM .

Ring Racepace. They modify the stock gears.

I've had hks three bolt pulleys for four years now with no problems. As mentioned above, even the cheaper knock offs are allright as long as the fasteners are good and they're done up properly.
