Tuning the Maruti / Suzuki Ertiga

"Tuning guide to the greatest Maruti Ertiga modifications."

The Ertiga is a great tuning project to play with. We see car owners wasting money on their Ertiga doing the wrong mods and then having to start over. Follow our hints to avoid ruining your car so we shall look into Ertiga tuning and summarise the optimum modifications.

Maruti Ertigas are fantastic to work on and with carefully chosen tuning modifications you can really increase your driving fun.

Handling/Suspension upgrades

Handling modifications are the thing most do first for the Ertiga.

We found that most Ertiga factory suspension setups need tweaking, a few degrees of toe out for cornering or toe in for stability, 1-1.7, and some negative camber will substantially enhance your cornering and handling.

We suggest that you fit sports suspension and lower the car by 22mm - 39 mm. Larger drops require arch work - especially on models already equipped with motorsport suspension.

Don't just look at the peak power figures, you need to see the whole torque curve when determining if a mod is right for you Ertiga.

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.

Getting the correct grade of modified upgrade kits for your planned usage of the car is vital. Stage 3 competition upgrades just won't work well on the road and will make the car undrivable.

Modifying to Stage 1:

 Remap, Panel air filter, Lighter flywheel, Suspension upgrade (drop 22mm - 39 mm.), Sports exhaust, Alloy wheels.

Modifying to Stage 2:

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

Modifying to Stage 3:

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

Peak power is nice in motorsport but for a daily driven car you need a long power band and perhaps extending the rev range.

The point of our guides is to give a brief overview of tuning modifications and point you in the right direction, our forum is the place to go for detailed advice and tips on your car tuning project, the best uprated parts and all aspects of modding cars.One of the best mechanical modified upgrades you can do to your NASP engine is to fit a fast road camshaft .

It maximises the intake and exhaust durations and increases 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 motor sports profile cam as this affects the engines idling and general town driving characteristics.

You will need to ensure that the engine is not starved of fuel so will need to look at the fuelling.

Most power losses, flat spots and erratic idling after uprated kits are done can usually be traced to fuel delivery or timing issues. Upgraded injectors will enable you to supply sufficient fuel to the engine.

Uprate the fuel pump to cope with the extra fuel requirements of your tuned Ertiga's uprated injectors.

Intake and Exhaust Tuning.

The next area for modification is the intake and exhaust. Contrary to popular belief there is often very little if any power gain obtained by fitting an induction kit, they only work well and are recommended after you raise the engines power to the point where the standard air intake box cannot cope!

For most Ertiga engines TorqueCars would suggest you just go with a washable panel air filter. On heavily tuned engines and turbo vehicles an induction kit will help release the power providing you address the problem of supplying cold air.

Sports exhausts balance the flow of gases through the engine. But if the exhaust pipe is too large, ie: over 2.5 inches bore, you will lose much of the exhaust flow rate and end up lacking power and torque.

Getting a professionally ported and polished head with larger valves can fully maximise your power gains. A good heavy duty fast road sports clutch will help to keep that power going where it should. Never make false economies or think that a standard OEM clutch to cope. The best mods we recommend for your Ertiga are fast road camshaft, remap, induction and exhaust, suspension.

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 impressive power gains and take full advantage of the strength of the block. Adding forced induction will see significant power gains but this is usually too expensive to be cost effective. It is usually easier to add a supercharger than it is to get a turbo working. With a turbo the boost curve is related exponentially to the engine speed making it harder to map.

Superchargers will give a boost which is directly proportional to engine speed so is simpler. Adding forced induction will nearly always require a lower compression ratio or water injection.

Alloy wheel upgrades.

As alloys are less heavy they improve performance and they help to cool the brake disks. Further improvements can be made to your cars handling with the addition of soft compound tire. Large Ertiga alloy wheels can decrease performance. If you get big alloy wheels you will be changing your final drive ratio.

With this in mind endeavour to keep the overall rolling diameter of the wheel the OEM setup. In all cases avoid going over 17 or 18 inches.
