aww rats, just when I thought that I had a great idea that would be new... Oh well, back to the drawing board cryb..
Courtenay Sport in Norfolk in England have produced just one of these conversions and were the first in this country.
Z22SE Supercharger Conversion
Our Supercharger Conversion was originally developed for the VX220 2.2 16v and features several components from the GM 2.0 supercharged LM850 engine, which was developed by Lotus, and is used by GM in the Saturn Ion Redline and the Chevy Cobolt SS in the USA. One major benefit of this is that the components are βOEβ fitment and durability tested, another being an inlet manifold featuring the laminova charge cooler fitted as standard.
We have successfully developed our second generation supercharger conversion from the original application in the VX220 for use in the Vectra B 2.2 16v and now also for the Astra G.
This is not simply a bolt-on addition but a fully engineered conversion. The most evident components being the supercharger and the inlet manifold. The laminova chargecooler is retained to keep inlet air temperatures as low as possible with an additional charge cooler water radiator fitted in front of the carβs original radiator. The head is removed to allow for the compression to be lowered down to 8.5:1, the inlet manifold is reworked to include additional injectors to deliver additional fuel when on boost and an additional fully mapable ecu is added to take control of the on boost fuelling. Re-work to the driven side of the supercharger assembly also had to be done to ensure that the drive belt is not fouled by the alternator or aircon housing. The development for Vectra B included re-routing of the aircon pipework to ensure that we kept the aircon on the vehicle and additional other re-work was carried out allowing clearance of the map sensor under the bonnet.
Driveability of the supercharger conversion is βOEβ with the car performing like a modified 3.0 V6, but with the scream of the supercharger to ensure you don't forget its there. Bundles of useable torque pulls the car smoothly from 2,000 rpm right up to the red line and completely transforms the vehicle.
With 240+ bhp and 220+ lb ft torque available from the Stage 2 conversion this offers a massive performance boost to the all alloy Z22SE engine.
Stage 3 conversion under development.
Available for VX220, Vectra B and Astra G. VX220 Full details on our VX220 page.
