Astra H VXR Sprint

The aircon compressor is being removed to save a couple of kilos, the associated pipework and condenser have already gone. It is not needed on a track day car.

The turbocharger is also being removed having covered only 12,000 miles for rework from K04 specification to K06. Having had regular oil changes there is no end float play so the turbo is suitable for rework. It is being reworked with a Billet K06 Compressor wheel, uprated 360 degree bearing pack (thrust bearing) and twin seals and exhaust (turbine) wheel cut back, plus the addition of a Forge Uprated Recirculation Valve.

The intercooler is being sent to Pro Alloy Motorsport for them to modify the outlet to the new spec 60mm outlet. When it goes back together the factory water radiator is being replaced with a Pro Alloy enlarged water radiator, ideal for track day use due to the larger capacity thicker core all aluminium unit.
