Our Stage 4 Conversion for Astra & Zafira VXR (Z20LEH) builds on the Stage 3 hardware components that are:
. Full Exhaust System, preferably 3” (76mm) throughout
. Large Intercooler
To this we add the following:
. K06 Hybrid Turbo
. Klasen High Flow Inlet Manifold
. Stage 4 Software
With our Stage 4 we have addressed the main issue and negative comments we have read & heard regarding other versions of the Stage 4; that is the lack of torque when compared to a Stage 3 or Stage 3+ (with a KO6 turbo).
