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!
