Tuning your Maruti 800.

"Tuning guide to the greatest Maruti 800 modifications."

The 800 was  a rebadged version of the popular Suzuki Fronte. They appeal to younger drivers and are quite often modified and tuned up.

They are easy to work on and with the right performance upgrades you can turn your 800 into something very special indeed.

The 800 is a good car tuning project to play with. The key to 800 tuning is choosing the right mods - a lot of money can be wasted if you do it wrong.

We review 800 tuning and summarise the best modifications. Maruti 800s are popular cars and with a few sensible mods you can really improve your driving enjoyment.

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

Enjoy your 800 to the full with our hot tuning pointers - do the right mods in the right order.

Smaller engines do not provide much of a return in terms of power so start with a bigger engine. Engine swaps are a good option if you have a small engine size.

Guide to the Best Tuning Mods & Upgrades

  1. Mods that Remove a Restriction

    If the intake or exhaust are restricted in any way this will have an impact on your cars performance, so use an induction kit/filter upgrade and better flowing exhaust whenever your tuning creates a flow restriction.

  2. Mods that Improve Handling

    Braking, Suspension and general alignment of the suspension components is vital for any tuning project even before you start increasing power.

  3. Fit Stronger Parts

    Tuned cars will show up weaknesses, typically in the turbochargers, clutch and internal engine components. Whilst most engines can cope with mild tuning mods, TorqueCars recommend that you upgrade the internal components before these weak spots manifest themselves.

  4. ECU Tunes & Remapping

    While some cars can be easily remapped, others may require piggyback ECU's or aftermarket ECU's but this is the most vital step of your tuning project as it fully releases the power from all of your mods and upgrades. Expect 10-20% on NASP engines and 30-40% on turbocharged units.

  5. More Power Needs More Fuel & Air

    Every tuning project will aim to increase the air supply, but fuel supply is just as vital and will need to match the air the engine can utilise. Fuel to Air ratio is vital so upgrade the fuel pump & injectors. Also you can look to perform head mods (flowing and porting), bigger valves, fast road cams and forced induction upgrades to improve fuel.

Stages of Tune

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

Stage 2 mods: Ported and polished head, Fast road cam, high flow fuel injector, fuel pump upgrades, Power/Sport clutch.

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

Peak power is all well and good but for a drivable and fun car you need a wide torque band and perhaps extending the rev range.

The aim of our articles is to give a limited introduction of customising modifications and point you in the right direction, our forum is where you can ask for more detailed advice and tips on your car tuning project, the best performance parts and all aspects of modding cars.A fast road camshaft proves to be one of the best NASP power modifications you can do from a single upgrade to your engine.

The exhaust & intake flow play a large part in your cars power band, but be careful here, getting this wrong can upset the idle and make the car hard to drive in traffic. You'd need to follow a camshaft upgrade with other mods and finish with a performance chip to fully release the power gain.

When pushing up the power you will need to pay attention to to the fuelling. More power needs more fuel.

If you find you get flat spots and power surges after your performance parts you should check the fuelling and try a higher octane fuel as well. Bigger injectors will enable you to supply sufficient fuel to the engine.

A fuel pump will only deliver a finite amount of fuel, so you may need to uprate this if your injectors are demanding more fuel.

Intake and Exhaust Tuning.

Breathing mods are usually next up. Contrary to popular belief there is often very little if any power gain to be had by fitting an induction kit, they only help and are recommended after you boost the engines power to the point where the standard air intake box cannot cope!

Maximum power gains come from a full induction kit with a cold air feed on heavily tuned engines, this can be sited within an air box but a performance panel filter should suffice for most applications. TorqueCars suggest you use a panel air filter as these are easy to clean and maintain and generally perform better than paper ones.

Sports exhausts generally help improve air flow from the engine but avoid an exhaust that is too wide or you may end up will reduce the flow rate. Stick to 1.5 to 2.5 inches as a rule of thumb.

Head work including a gas flow (ported and polished) and 3 or 5 angle valve job will really help to release the potential of the engine. Your clutch can slip as you increase the power if it starts to break and the standard clutches are only ever good for power gains of up to 45%. Fit an upgraded clutch to avoid power loss through the transmission. The best mods in our opinion for your 800 are remaps, sports camshafts and induction improvements.

Turbo engines are just pleading to be remapped. You will see phenomenal power gains on most modern turbo engined cars including diesels making a remap one of the most cost effective and phenomenal modifications for your money.

We've also come across some owners toying with twincharging applications and making some seriously high power gains.

Adding forced induction will see massive power gains but this is usually too expensive to be cost effective. Turbos are generally harder to add than a supercharger. Turbos give boost in exponential proportion to increasing engine speed and this can make mapping difficult.

The nice directly proportional boost and rpm characteristics of the supercharger make them more straightforward to map. To cope with forced induction you will usually need to decrease the compression ratio of the engine .

Handling/Suspension upgrades

Handling modifications are often a priority for the 800.

Good suspension tweaks that radically benefit handling for the 800 include a couple of degrees negative camber and 1-1.5 degrees of toe out on the front wheels.

We suggest that you fit performance suspension and lower the car by 26mm - 38 mm. Larger drops require arch work - especially on models already equipped with performance suspension.

Alloy wheel upgrades.

Alloy wheels will help the brakes cool down and are generally lighter than the steel ones. Get a good track legal slick tyre to improve your handling and help improve traction on your 800. We'd like to point out although they can look cool on the 800 large alloys 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.

Although some people have fitted larger wheels without problems we would stick to a 16 inch rim size as the maximum.
