Project Do It All S13, Assembling the Bulletproof SR20DET Cylinder Head!

In addition to the Supertech valve seals we also used new Supertech valve keepers. The Supertech keepers are machined out of hardened chrome moly steel and are nitrided for wear resistance.

We are running JWT adjustable cam timing gears.

The JWT gears adjust with a combination of different holes and skipping teeth.  The advantage of this is simplicity and there will never be any chance of your adjustment slipping or shedding bolts into your crankcase!

The JWT gears feature induction-hardened teeth for wear resistance and a long life.
