| We have taken the development of tuning packages for the 2.2 VX220 very seriously from the day it was launched. One of our own cars (sadly no longer with us as it had to make way for an Astra VXR for further development) is pictured below proudly wearing the registration number A11VXL. Our range of 2.2 Tuning Packages and products help to improve the cars performance and driveability, as we understand that alot of owners do not necessarily want, for one reason or another, to change to the turbo to get performance gains. This range of packages improves the 2.2's potential, and culminates with supercharger conversion that takes the car to over 240 BHP, whilst retaining all the standard drivabilty. This gives the 2.2 VX220 a huge torque increase and a power to weight ratio of around 275 bhp per ton!! Quite impressive when the standard VXT offers 211 bhp per ton. |
Our CS3, CS4 and CS5 Tuning packages include a Rolling Road Tune.

Our new supercharger conversion for VX220 2.2 16v features many components from the 2.0 supercharged LM850 engine, which was developed by Lotus, and is used in the Saturn Ion Redline and the Chevy Cobolt SS. One benefit of this is that all components are OE fitment & durability tested, another being an inlet manifold featuring the laminova charge cooler fitted as standard. |
| To give you an insight into our Supercharger Conversion here is what is involved, as there is more than simply just a supercharger to 'bolt on' to the engine, which is the common mis-conception. The price of the conversion includes full fitting, mapping and setting up on the rolling road. So what exactly is involved? For converting the VX220, firstly the front clam has to be removed from the vehicle. The supercharger and inlet manifold are fitted to the engine, however the supercharger is modified from standard GM specification to suit our 2.2 application. The alternator is modified to allow the inlet manifold suitable clearance, and an additional pulley and bracket is fitted to allow the correct belt run for the supercharger, and to space the alternator the correct distance for the new set up and belt run. The original drive belt is replaced with a longer Continental belt. For Stage 2 a vertical water radiator (chargecooler pre-rad) is fitted at the front end of the car in the crash sturcture apperture (an extra large charge cooler pre-rad can be specified as an option) and the pipework is routed from the engine bay to the water pre-rad at the front via the driver's side sill. This is required to cool the water used in the chargecooler system, which reduces inlet air temperatures making use of the laminova core heat exchanger in the supercharger inlet manifold. The standard ecu is re-located (as it is not posible for it to sit where it does on a standard car) and the factory wiring loom is extended accordingly. The standard ecu is then remounted onto a new bracket. Higher flow injectors are fitted together with a new map sensor whilst the radiator top hose and fuel pipes are run for better clearance. Once the conversion is completed, the front clam is then re-fitted. The OEM ECU is then remapped with our own developed software, specifically for the supercharger conversion, prior to a first short shakedown road test. Following road test the car is set up on the dyno and any changes that are required to the software are made. Finally the car is then fully road tested again for driveability. In addition to the modified GM supercharger and inlet manifold the components required for the conversion also include a chargecooler water radiator, a high flow bosch water pump, an inlet manifold gasket, supercharger to inlet manifold gasket and alignment bungs, throttle body to supercharger plate, pipework for chargecooler system including silicone elbows, relay, 4 high flow injectors and assosciated fittings, fuel pipe, fuel pipe fitting, additional bracket and pulley, longer continental drivebelt and all the required nuts, bolts, washers, wiring and hose clips. To date there are now some 100+ conversions thorughout the UK and Europe, with cars in Germany, France, the Netherlands, Norway and Greece. And what is the finished car like? Here's a short video clip of one in action. |

VX220 2.2 16v Supercharger Conversion Stage 1 210bhp and 190-195 lb ft torque. - £3830 fully fitted and set up including VATThe Stage Two conversion offers 240+ bhp with around 215-220 lb ft torque, and now includes a front mounted charge cooler pre-rad. The Stage Two conversion is priced at £5465 fitted including VAT. Please Note: The Stage Two conversion requires a full sports exhaust system. For any car not fitted with a full sports exhaust system, we offer a system at a reduced price when fitted at the time of the conversion. Upgrades for Stage 2 conversion, for cars more biased towards heavy track use are available and include: All Alloy Water Radiator in place or 'OE' radiator which has plastic end tanks, extra large pre-rad with twin fans for the charge cooler system to provide additional inlet air cooling and an extra large header tank for the charge cooler system, |

| providing a much greater volume of water for the system. Please ask us for further information and we will be happy to discuss options. Stage 3 conversion under development and testing which includes newly developed software, re-worked cylinder head and steel rods with expected figures of around 290 bhp, and with the option of cams, uprated pistons and harrop supercharger for bigger gains. 360 bhp has been seen so far! |

Our sports camshafts are profiled to suit fast road use offering good benefits in power and torque across the rev range. The power gain will be felt right across the rev range building strongly from 4000 rpm. With an ECU remap gains to 15bhp can be seen. Kit includes Uprated Schrick Camshafts with double valve Springs and collets. Note: These cams may required slight head maching work to allow the double valve springs to seat correctly (at additional cost). Schrick Camshafts (outright) £1247 Fitting Available. |

This lowers the final drive ratio of the F23 gearbox on the VX220 2.2 16v by 5.8% for faster acceleration. Price £POA |
| Alloy bottom pulleys are now available for the Z22SE engine. Machined from 6082 T6 billet alloy, they are balanced to a higher specification than the OE units, with no rubber core to perish and split away, improve engine response and allow for smoother high rpm running. A weight saving of 1kg is seen, with the new pulley tipping the scales at about 0.6 kg. Z22SE Multi V Alloy Pulley £155 |

| The Viper induction kit differs from most induction kits by the fact that the filter element is insulated from picking up hot air (which is not good for power) by a carbon fibre casing. The kit comes complete with a cold air feed and inlet trumpet so that the air can be drawn directly from a high pressure point in the side pod. Viper Induction Kit £255.50 |
