Astra H VXR Stage 4 K06 Coversion
Another fabulous conversion on an Astra H VXR. This car first came to us for mapping to Stage 3 (hardware requirements are a full 3″ exhaust system and uprated intercooler). The car was fitted with a Forge lower front mount intercooler, but on the exhaust side only had a pre-cat removal pipe, and a Piper […]
Astra H VXR – K06 Mapping
This Astra H VXR Nürburgring is a well loved and enjoyed example having covered some 110,000 miles, but it always gets regular 5,000 mile oil changes. It shows the durability of the engines as this car has been tuned to several levels, originally starting at Stage 3. More recently it has benefitted from the addition […]

Another K06 conversion, with steel rods, Courtenay high flow inlet manifold, 3″ exhaust and CSR Intercooler being set up on our rolling road – bang on the money power and torque wise, and one of the cleanest and best prepared cars we’ve seen. We have also switched it to Evans Power Cool 180 Waterless Coolant. […]
Turbo Failure – The Truth About Dirty Oil………
…… and how it will kill your turbo. All too often we hear of turbo failure of the K04 turbocharger, as used on the Z20LEx engines in Astra G and H, Zafira A and B, VX220 and all too frequently we hear the turbochargers being blamed as poor quality or ‘rubbish’ units, which is not […]
