Fast road camshafts for the Vauxhall Z20 turbo engines
These are designed to enhance power in the mid to top end of the powerband, whilst being compatible with all of the standard valvetrain.
These are fine to fit with standard springs, however we would recommend the use of Cat's single springs if you were going to race with them, as they handle the high rpm's better.
We recommend the fitment of our stem seal retainers, which we also provide as a kit with the single springs.
We also recommend the fitment of our adjustable cam pullies, to ensure you extract the most from your cam setup.
