Pair of Adjustable Cam Pulleys for the Vauxhall Z20 engine.
These pulleys will allow you to time your camshafts to deliver maximum power where you want it, ideal for use with aftermarket camshafts, or the cams from the naturally aspirated X20XEV engine in your turbo Z20.
The Exhaust Pulley includes the sensor ring on the back, so that the ECU is kept happy no matter where you position your cams.
This is for a pair of Pulleys as pictured above. See our other adverts for each pulley individually.
You probably also want to consider a fresh cambelt and waterpump whilst you are in there replacing these, which are also available from us.
