Vauxhall Omega Tuning

"Omega - the last letter in the Greek Alphabet"

The Omega was Vuaxhall large executive car designed to take on the Vectra. The Omega suffers depreciation like a war zone holiday villa which means there are some bargains to be had.

 Improving the handling should be your first priority in your Omega tuning project. We suggest that you fit uprated suspension and lower the car by 30-35mm. Larger drops require arch work - especially on models already equipped with sports suspension.

Our aim in Omega engine tuning should be to increase peak power and Torque at the top end.

Smaller engines do not provide much of a return in terms of power so start with a bigger engine. TorqueCars recommend the 2.5 V6 or the 3.0, sadly the diesel engines are too agricultural and offer little to the tuner. Engine swaps are a good option if you have a small engine size, look to the Vectra and Calibra for suitable engine donors.

This will help to ensure you retain some economy low down. One of the best mechanical mods you can do is to fit a fast road cam. Don't forget to uprate the fuelling when you are increasing the power - it makes the car more thirsty. Improve your cars response to the throttle with a Fuel pressure boost valve. To get sufficient fuel you may need to uprate the injectors on your engine. A fuel pump will only deliver a finite amount of fuel, so you may need to uprate this.

Vauxhall Omega Intake and Exhaust modifications are popular options for most tuning projects. The next area for modification is the intake and exhaust. Induction kits work well on turbo engines and larger engines, for the smaller Omega engines you should go with a sports panel air filter. Sports exhausts will certainly help air flow through the engine but do not go too large. Stick to 1.5 to 2.5 inches for best results.

A good fast road power clutch will help to keep that power going where it should. Never skimp or expect a standard clutch to cope.

Lets look now at Vauxhall Omega Wheel modifications. Because alloy wheels are lighter they improve performance and they help to cool the brake disks. It is worth noting that although they can look cool on the Omega Big alloy wheels will actually decrease your performance. The larger you go the lower you top speed will be due to the change in your effective final drive ratio. Although some people have gone larger we would stick to a 16 inch rim size as the maximum.
