Many Mokka owners uprate the handling of their cars as a priority, this will certainly increase your enjoyment of the car. 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 Mokka with a nice fat peak torque band.

Mokka make good sleepers if you debadge them and fit the most powerful engine mods and handling mods you can source!

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.

These are the mods that are usually performed by our members, decide how far you want to push your car before you get going.

Getting the best mods for your planned usage of the car is essential. Stage 3 competition upgrades just won't work well on the road hard to control in slow traffic.

Best Engine Mods for your car

  1. Mapping - remapping provides the most advantage in terms of cost savings,  aftermarket ECUs, and piggyback ECUs are all alternatives.
  2. Fast road cams are one of the most significant mechanical changes, but they must be installed by someone who knows what they're doing and they are not always easy to source but you might find a local firm to regrind a stock camshaft.
  3. Intake and Exhaust - Note that on their own these mods will NOT ADD POWER in most cases, but they can help enhance power after other mods by removing the restriction.
  4. Upgrades to turbochargers and superchargers - forced induction is the most efficient approach to increase air supply, allowing you to burn more fuel and make more power. It is one of the most costly upgrades but provides the best gains.
  5. Head work - The goals of porting and flowing the head are to get air flowing into the engine while removing flow restrictions and turbulence.
  6. Typical stage 1 mods often include:
    Remap,Sports exhaust,Suspension upgrade (drop 30-40mm),Lighter flywheel,Alloy wheels,Panel air filter.

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

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

    Your goal when tuning should be a wide torque curve. You want to avoid sending all the torque to be at the top end of the rev range unless you are creating a competition car. The aim 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 best place to go if you need more detailed advice and tips on your project and all aspects of modding cars.One of the most cost effective mechanical modifications you can do to your NASP engine is to fit a fast road cam.

    The intake and exhaust durations play a large part in your cars power band, but be careful here, getting this wrong can upset the idle and make the car difficult to drive in traffic. You'd need to follow a cam upgrade with other mods and finish with a reflashed ECU for the best performance gains.Don't forget to uprate the fuelling when you are increasing the power - it makes the car more thirsty.

    Using higher octane petrol is another option if you find you are suffering from detonation or premature ignition on your Vauxhall project after fitting other modifications. Uprating the injectors is another beneficial modification and will deliver sufficient fuel. Uprate the fuel pump to cope with the extra fuel requirements of your tuned Mokkas uprated injectors.

    Intake and Exhaust Tuning.

    Breathing mods are usually next up. Contrary to popular belief there is often 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 Mokka engines you should go with a performance panel air filter preferably made from cotton.

    Sports exhausts can help equal out the flow of air through the engine. But if your exhaust is too large, ie: it's over 2.5 inches bore, you will lose a lot of the flow rate and end up lacking power and torque.

    Getting the head gas flowed will help get more air into each cylinder. This is definitely a job for a pro with a flow bench. When you start tuning your Mokka you will see that the standard clutch starts to complain 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 phenomenal power gains and take full advantage of the strength of the block.

    We've also come across some owners toying with twin charging applications and making some seriously high power figures.

    The most significant power gains for NASP engines usually involve the addition of forced induction. Superchargers are generally easier to add than turbos. Turbos increase power in increasing proportion to increasing engine speed and this can make mapping difficult. The nice correlating boost and rpm characteristics of the supercharger make them easier to map. Decreasing the engines compression ratio will allow you to add forced induction, water injection may also help prevent detonation.

    Alloy wheel upgrades.

    Alloy wheels will help the brake cooling and are generally less heavy than the steel ones. Large Mokka alloys can decrease performance. If you get big alloys you will be changing your final drive ratio. Although some people have installed larger rims without issues we would restrict ourselves to a 18 inch rim size as the maximum.
