Gtr Rb26 Aftermarket Cam Gears

[paulyp]

Hi all,

Just fitting some adjustable cam gears onto my GTR R32 and have noticed that the cam gears I have do not state inlet and exhaust.

Has anyone come across this because I have noticed some do state "inlet" and "exhaust".

Also I have two sets. Any suggestions which ones would be best to use.

One is a generic no name Tomei look alike and the other one is Envy Dyno which appears to be modified standard cam gears and also is noticeably heavier.

Cheers!

Doesn't matter afaik. Can use them on either side.

That's right, it doesn't matter as long as the locator dowel and timing mark are aligned. So on those pulleys which have two dowel holes you should put the cam dowel in the one aligning with the timing mark.

I can't understand why there would be two dowel holes on a pulley anyway, can anyone shed some light on this?

Edit: If you think they are copy tomei pulleys your priority should be upgrading the adjuster bolts to grade 8.8 or 12.9 bolts. Some fakes are known for having crap bolts.

Thanks guys. Much appreciated.

Yeah it is strange how some have two dowel holes unless it's made to suit more than one engine??

I am thinking the envy dyno ones may be the way to go because they are heavier and seem to be modified oem so it should be stronger. But I am just guessing here.

Anyone know if some cam gears are better than others or is just all the same either way?

My guess - easy way to get the balance about right.
