I actually thought there was a phasing at 4K.

So there are more robust pads that are available...this good news...are they 996 part number revisions? When is someone going to design "metallic" roller pads??

I will have to have to have the facilities and know how to drop the engine by then. Once I have that can this work be done by a non expert?

Vario-Cam is a single timing change @ 2200-2500 rpm & it really helps from 4000rpm up. There is a update kit containing 2 pads & 1 o-ring to do 1 Vario-Cam tensioner so you need 2 kits. The wear pad has to be softer than the chains so that the pads wear & not the chain. The cams have to be removed & re-timed so you need special tools
