Vauxhall Cascada Tuning

Tuning the Vauxhall Cascada and best Cascada performance parts.

We look at Cascada tuning and report on the optimum modifications. Vauxhall Cascadas are popular tuning projects and with carefully chosen performance tuning mods you can greatly increase your driving pleasure.

The Cascada is popular among our members for tuning projects but we strongly recommend that you sit down first and research Cascada tuning to avoid making the usual expensive errors we see.

Improving the handling should be your first priority in your Cascada tuning project. Drop the car by as much as 35mm and fit stiffer dampers, bigger drops will need other modifications in most instances.

Top end power should be your overall aim on the Cascada with a nice fat peak torque band.

Keep your car looking standard but remove the badges to make an awesome sleeper!

The best power gains come from larger engine sizes. The more you start with the bigger the return on investment so engine swaps are good value mods for small engined cars.

Engine tuning mods.

This list of the stages and mods that are usually performed by our members, decide how far you wish to go in your tuning project before you start.

Getting the best mods for your planned usage of the car is essential. Stage 3 motorsport parts just don't work well on the road making the car difficult to drive.

Stage 1 mods: Sports exhaust,Panel air filter,Alloy wheels,Lighter flywheel,Remap,Suspension upgrade (drop 30-40mm).

Stage 2 mods: Fast road cam,Ported and polished head,Fuel injector & fuel pump upgrades,Power clutch,.

Stage 3 mods: Competition cam,Sports gearbox,Adding or upgrading forced induction (turbo/supercharger),Engine balancing,Internal engine upgrades (pistons/head/valves).

Your aims when modding your car should be a nice flat torque curve. You want to avoid sending all the torque to be at the top end unless you are creating a competition car. The whole point of this article is to give a little insight into the world of car tuning modifications and point you in the right direction, our forum is where you can ask for more detailed advice and tips on your project and all aspects of modding cars.One of the biggest mechanical modifications you can do on your NASP engine is to fit a fast road cam .

It maximizes the intake and exhaust durations and pushes up the power if done right. Ideally you'd add other mods and finish up with a remap. We'd also caution you not to go with a competition cam as this upsets the engines idling and general town driving characteristics.When pushing up the power you will need to pay attention to the fueling.

More power needs more fuel. Using high octane petrol is another option if you find you are suffering from detonation or premature ignition on your Vauxhall project after fitting other modifications. To get sufficient fuel you may need to uprate the injectors on your engine. Uprate the fuel pump to cope with the extra fuel requirements of your tuned Cascadas uprated injectors.

Intake and Exhaust Tuning.

The next area for modification is the intake and exhaust. Contrary to popular belief there is generally very little power gain to be had by fitting an induction kit, they only become beneficial and are recommended after you increase the engines power to the point where the standard air intake box cannot cope! Induction kits can work well on turbo engines and larger engines (if supplied with a suitable cold air feed or air box), generally though we'd just recommend for Cascada engines you should settle for a performance panel air filter preferably made from cotton.

Sports exhausts will certainly help air flow from the engine but do not go too large or you could will reduce the flow rate. Stick to 1.5 to 2.5 inches for best results.

Getting a professionally ported and polished head with larger valves can fully maximise your power gains. When you tune up your Cascada you will see that the standard clutch starts to fail so get an uprated clutch. NASP engines do not achieve big power gains if you remap them, unless you have done extensive modifications. With turbocharged engines this is another story. A remapped turbo will give big power gains and take full advantage of the strength of the block.

We've also seen some tuners toying with twincharged conversions and making some impressively high power figures.

Despite the large cost involved adding forced induction to a NASP engine will give large power gains. Turbos are usually harder to add than a supercharger. It is more challenging to map a turbo as the boost comes on exponentially with revs. It is easier to map a supercharger because the boost is proportional to engine speed on a linear curve. Adding forced induction will usually require a lower compression ratio or water injection.

Alloy wheel upgrades.

Alloy wheels will help the brake cooling and are generally lighter than steel ones. We should point out that although they can look cool on the Cascada big alloy wheels will actually decrease your performance. The larger you go the lower your acceleration will be - this to the change in your effective final drive ratio.

With this in mind aim to keep the overall rolling diameter of the wheel your OEM settings. In all cases we do not recommend going bigger than 16 inches.
