The first lot of AVCS heads came out with inlet only variable cam timing, the latest offreing has inlet & exhaust. The AVCS is obviously computer controled, via the ECU, however the same results can be had with vernier cam wheels. The AVCS uses oil pressure driven by a solenoild to change the timing of the cam position.

Couple of links for you.

Modifying AVCS

Subaru AVCS
Thanks for the links Simon, I couldn't see why gains couldn't be made even with the non AVCS donks, I've serched Rexnet & NASIOC with no real answers, only more to do with dialing A/M cams, I would like to see if some one has done it and come up with the goods,
Reason im asking is i'm about to change my timing belt and thinking of shoving a set of vernier gears in.
