As some people know the astra VXR (Z20LEH) has Mahle forged pistons as standard, the biggest factor which prevents the Z20LEH engine making big power is the Rods. These are rated to around 320BHP, anything over this we would highly advise fitting stronger Forged Steel Rods. Once these are fitted along with some uprated valve springs the Z20LEH engine is capable of over 500BHP.


This is a common upgrade and to make things simple this kit is for Ashford Performance Ltd to supply and install all the neccesary parts to install the I Beam rods and uprated valve springs.

4x Forged I-Beam Rods

4x Rod Bearings

4x Piston Ring Sets

1x Full top end gasket set

1x Full bottom end gasket set

1x Cambelt kit
