Cat cams Semi Race Cams for Vauxhall Z20 Engine

 

These semi race cams are as wild as you can go on the standard hydraulic lifters fitted to the Z20 engine.

These cams should be fitted with some uprated single or double valve springs which we have stock of either Cat cams or Piper.

The fitment of a fresh set of hydraulic lifters is wise when fitting these cams, however a very low mileage set should be fine.

 

Specs for these are as follows;

Intake / Exhaust

Duration @ 0.1mm = 275°/259°

Duration @ 1mm = 237°/218°

Maximum lift = 11.15mm/10.20mm

Lift at TDC = 2.05mm/0.25mm

 

Will do around 550 bhp with no problems!
