Adjustable Cam pulley for the Inlet and Exhaust Camshaft of the Vauxhall Z20 engine.
This pulley will allow you to time your camshafts to deliver maximum power where you want it, ideal for use with aftermarket or alternative OEM camshafts in your turbo Z20.
It includes the sensor ring on the backside, as shown in the picture above, so that the ECU is kept happy no matter where you position your exhaust cam.
For maximum performance when fine tuning on the dyno we recommend using a pair as this will then allow you to fine tune both the advance and the overlap to extract maximum performance from your engine.
This is just for the one Cam Pulley pictured in the first picture above. See our other adverts for a combo of both at a discounted price.

You probably also want to consider a fresh cambelt and waterpump whilst you are in there replacing these, which are also available from us.
