Anyone have a interested in buying a set of these adjustable cam pullyes that baza found,

We can get around the pulley adjustment with offset keys.

It is the inlet cam that needs an adjustable gear.

If we shave heads we effect both cams?

Yes,
Actually, all four.

To set the valve timing to what it should be, you need to be able to adjust both cam positions.

Yep.I heartily agree with what this esteemed statesmen has said! However since we need to have more than yep in the reply I will honor Him in a courtius and respectful way.
Thank you Harvey!

So we need what this guy has: http://wrxmodders.com/forums/viewtop...r=asc&start=15

Plus the sprockets. Wonder how much that would cost.

To quote the master.
Yep.

Yes those look the goods.
Maybe some body could make a set.

Snazzy. Obiously these wouldn't work with the OEM pulley removal tool though. Chain wrench it is!

I just noticed these on evilbay and came on the forum to find out what tuners thought.
So what's the consensus? Seems to me that to be effective, intake and exhaust needs to be separately adjustable. My build is 11:1 forged pistons, ported heads, modestly ground cams and long tube headers. Still using the OEM buckets. I don't remember if the cam timing was changed on the grind. Probably not.
How much benefit would there be?
Thanks in advance.

Yes those look fine. They will move both cams, so the adjustment will retard or advance the inlet and exhaust cams. Good for some fine adjustments.
One tooth is about 14.5*, so if it can be adjusted that far, it will be worth it.

To be able to alter both cam timings, we need both that pulley, and an adjustable gear on the exhaust cam.

You'll need both...an adjustable belt gear and one adjustable inlet cam gear.

That would do it.

I'd be in if somebody was able to organise both.

Don't know, but I think it would be easier to make the gear on the exhaust cam adjustable, its just a plain gear. The inlet has the rattle gears on it, still work the same.

Yes I'd forgotten about that. I think you're right.
