Obviously with so many engine options we will have to keep this guide relatively simple but we are expanding our articles to focus on the specifics of each engine and can provide a more nuanced range of tips and mod recommendations on them.

You can do much to improve the performance of your Vitara with our step by step tuning tips. The key to Vitara tuning is getting the right mods - a lot of money can be wasted if you do it wrong.

Handling/Cornering & Braking Mods

Improving the handling should be your first priority in your Vitara tuning project. Drop the car optimally somewhere in the region of 45mm and fit stiffer dampers, bigger drops will need other modifications in most instances.

If you intend to use the car off road then you should just stiffen the suspension a little, perhaps raising the ride height and fitting larger chunky tyres.

Suspension Upgrades

For off-road enthusiasts, upgrading the suspension to a more rugged, adjustable setup can improve handling on uneven terrains.

Coilover kits from brands like AP Coilovers and KW Variant are good options for those looking to balance on-road and off-road performance.

You will find that the adjustable kits which cost more are better suited to the Vitara, allowing you to tweak the balance between practicality and handling.

Tires and Wheels

Upgrading to off-road tires and stronger wheels can significantly enhance the Vitara's capability on rough terrains.

Bear in mind that chunky tires will increase road noise and harshness, but will really come into their own on rough terrain.

Brake Upgrades

Upgraded brake pads, rotors, and calipers can improve stopping power, essential for both safety and performance. Consider EBC or Ferodo pads for reliable upgrades or let us know in the comments which brands you've used and recommend so we can share these.

Our aim in Vitara engine tuning should be to increase peak power and Torque through the entire rev range.

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. The turbo diesel engines can be readily chipped or tuned/remapped for quite a noticeable power hike.

Engine tuning mods.

These are the mods that are usually performed by our members, decide how far you want to go before you start.

Getting the correct grade of mods for your planned usage of the car is vital. Stage 3 motorsport mods just don't work well on the road difficult in stop start traffic.

Best Engine Mods for your car

1. Engine Tunes - engine tuning/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.

Vitara Tuning Stages.

Typical stage 1 mods often include:
Alloy wheels,Lighter flywheel,Remap,Suspension upgrade (drop 30-40mm),Panel air filter,Sports exhaust, ecu mapping or piggyback ecu.

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

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

Your aims when tuning should be a flat and wide torque curve. You don't want all the torque to be at the top end unless you are creating a motorsport car. In this article we shall give your a good starting base to the best performance parts for your car, but we'd encourage you to spend some time on the site looking into the details of each type of performance modification.

Fast road cams offer one of the biggest performance gains for your money on non variable valve timed engines as far as a bolt on part goes on a NA (naturally aspirated) engine.

It improves the intake and exhaust flow and pushes up the power if done right. Ideally you'd add other mods and finish up with a reflashed ECU.

Expect to see around 10% on most Vitara NASP engines. Most newer models can be flashed via the OBDii port. The 1.4 booster jet uses the popular Bosch MED17.9.63 so there is plenty of expertise out there and you'll see around 30hp and 40lbft boost with a map on those engines.

TorqueCars would caution you not to go with a motor sports profile cam as this affects the engines idling and general town driving characteristics.

Aftermarket ECU Upgrade

At the heart of any vehicle's performance lies the Engine Control Unit (ECU), a critical component that regulates functions such as ignition timing and fuel injection.

Opting for an aftermarket ECU, notably the well-regarded ME221, introduces a new dimension of control over your Vitara's engine operations.

Such an upgrade facilitates the meticulous adjustment of engine settings, paving the way for notable improvements in performance metrics, fuel economy, and responsiveness. The ME221 ECU, in particular, allows owners to fine-tune their Vitara to align with their driving preferences, be it for the daily commute or more spirited driving adventures on weekends.

The adaptability and precision that an aftermarket ECU introduces are invaluable for tuning aficionados, making it an essential modification for those seeking to optimize their vehicle's capabilities.

Throttle Body Upgrades

Throttle bodies play a pivotal role in regulating your engine's air intake, directly influencing performance. By upgrading to larger and more efficient throttle bodies, your Vitara's engine can achieve improved airflow, which translates to an uptick in horsepower and torque figures.

Such modifications lead to a noticeably sharper throttle response and a significant uplift in the engine's overall performance. Coupled with a fine-tuned ECU, these enhanced throttle bodies ensure that your Vitara operates with utmost efficiency, enhancing both the thrill and engagement of the driving experience.

For enthusiasts eager to amplify the power and responsiveness of their Suzuki Vitara, investing in throttle body upgrades is a decision of paramount importance.

You will need to ensure that the engine is not starved of fuel so will need to uprate the fuelling. If you find you have flat spots and surges after your mods you should check the fuelling and try a higher octane fuel as well.

Uprated 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.

The next area for modification is the intake and exhaust. Please note that WE DO NOT RECOMMEND INDUCTION KITS, unless you have tuned your car extensively and are finding that the standard air intake has become a restriction.

Improving the air intake and exhaust system can enhance performance and efficiency. Consider induction kits for heavily tuned engines and performance panel filters for most applications. For exhausts, brands like Fox, Janspeed, Jetex, Piper, and Remus offer options that improve flow and sound.

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 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 can help increase the flow of gases through the engine. But if the exhaust pipe is too big, ie: it's over 2.0 inches bore, you will lose a lot of the flow rate and end up losing power and torque.

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. A good fast road upgraded clutch will help to keep that power going where it should. Never cut corners or expect a standard OEM clutch to cope. Turbo engines are just crying out to be Upgraded. You will see significant power gains on most modern turbochaged cars including diesels making a tune/remap one of the most cost effective and significant modifications for your money.

We've also come across some owners playing with twincharged conversions and making some impressively high power hikes.

Adding forced induction will see large power gains but this is usually too expensive to be cost effective. It is usually simpler to bolt on a supercharger than it is to get a turbo working. Turbos increase power in exponential proportion to rising engine speed and this can make mapping difficult. Superchargers will give a boost which is directly proportional to engine speed so is 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.

Because alloys are lighter they improve performance and they will help to cool the brake disks. We'd like to point out although they can look cool on the Vitara 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. For this reason we would advise sticking to a maximum wheel size of 17-18 inches, although we know some of our members have installed larger rims with no problems.
