Tuning the Suzuki Cultus Crescent / Esteem

"Thank you for reading our Suzuki Cultus Crescent / Esteem tuning tips."

The Cultus Crescent / Esteem is a good car tuning project to take up your weekends. If you do your research then you can create an awesome Cultus Crescent / Esteem but don't be fooled there are lots of high performance mods out there that will simply not suit it read our unbiased guides first.

The Cultus Crescent was launched in 1995 and aimed at the subcompact market, it has sold quite well and was rebadged Esteem in North America. It is nice to work on with a good range of engines and benefits from Suzukis legendary reliability.

We review Cultus Crescent / Esteem tuning and provide tips on the best modifications for your car. Suzuki Cultus Crescent / Esteems great bases for a tuning project and with carefully chosen upgrades you can maximise your driving opportunities.

Handling/Suspension upgrades

Many Cultus Crescent / Esteem owners uprate the handling of their cars with performance suspension kits as a priority, this will certainly increase your enjoyment of the car.

We found that most Cultus Crescent / Esteem factory suspension setups need tweaking, a few degrees of toe out for cornering or toe in for stability, 1-1.7, and a little negative camber will dramatically improve your cornering and handling.

We would go to a maximum drop of 24mm - 44 mm. on most models. You risk compromising your handling if you go lower than this.

Turning our attention to the engine we need to get a bit more power out of the top end.

Cultus Crescent / Esteem make good sleepers if you debadge them and fit the most powerful engine mods and handling mods you can find!

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.

Power mods.

Typically these parts are usually installed by our members, decide how far you want to push your car before you get started.

Getting the best uprated upgrades for your planned usage of the car is essential. Stage 3 competition upgrades just don't work well on the road and will make the car undrivable.

How to tune your car

  1. Improve the handling

    Focus on Suspension improvements, such as coilovers and make sure the bushings are in good order and that the alignment is correct. Then focus on improving the brakes, with a big disk brake conversion kit and fast road brake pads.

  2. Remove restrictions

    Focus on the intake and exhaust with filters being the common point of restriction in a tuned car. Intercoolers may also become restrictive on turbo engines so this may also need to be uprated.

  3. Burn more fuel & air

    Increase the fuelling so it matches the air coming into the engine. The ratio is important so you need to improve the fuel pump and injectors, so the head mods, big valve conversions, fast road camshafts and forced induction upgrades extra supply of air is adequately met.

  4. Test and replace any weak parts

    Weak areas are commonly the clutch, the turbocharger and pistons and crankshaft in a highly tuned engine. Makes sure these components will cope with your power aspirations.

  5. The Tune or Remap

    A cars ECU controls the fuel, timing, spark and even the turbo in some cases, so to fully extract your gains you should remap the car last and this will fully release the power. Some cars are easy to map, and others require piggyback ECU's or aftermarket ECU's but this is the most vital step of your tuning project.

Modifying to Stage 1:

 Sports exhaust, Remap, Alloy wheels, Panel air filter, Lighter flywheel, Suspension upgrade (drop 24mm - 44 mm.).

Modifying to Stage 2:

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

Modifying to Stage 3:

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

Your aim when tuning should be a wide torque band. You want to avoid sending all the torque to be at the top end unless you are creating a motor sport car.

The whole aim of our pointers is to give a brief overview of modifying performance parts and point you in the right direction, our forum is best place to go if you need more detailed advice and tips on your customized car project, the best modified kits and all aspects of modding cars.A fast road cam usually proves to be one of the best NASP power mods you can do with a single part fitted to your engine.

The intake & exhaust durations play a huge role 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 cam upgrade with other mods and finish with a reflashed ECU to fully realise your gains.

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

If you find you experience flat spots and surges after your sports mods you should check the fuelling and try a higher octane fuel as well. Increasing the injectors is another beneficial modification and will deliver sufficient fuel.

If you've uprated your fuelling with bigger injectors you will also need to get a bigger fuel pump to supply it.

Intake and Exhaust Tuning.

The next area for modification is the intake and exhaust. Please note that WE DO NOT FIND IMPROVEMENTS WITH INDUCTION KITS, unless you have tuned your car with over 30 percent more power and are finding that the standard air intake has become the bottleneck.

For most Cultus Crescent / Esteem 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 needing cold air.

Sports exhausts generally help improve air flow out of the engine but avoid an exhaust that is too large or you could will reduce the flow rate. Stick to 1.5 to 2.5 inches for best results.

Airflow through the head can be dramatically increased with some professional flowed (porting and polishing). These should match and be setup to take into account any other engine mods. Your clutch can lose you loads of power as you increase the power if it starts to complain and the standard clutches are only ever good for power gains of up to 48%. Fit an uprated clutch to avoid power losses through the transmission. The best mods in our experience for your Cultus Crescent / Esteem are a remap especially on a turbo, a fast road camshaft and sports exhaust, with a good air intake.

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 massive power gains and take full advantage of the strength of the block.

We've also come across some owners experimenting with twin charging conversions and making some very 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. With a turbo the power curve is related exponentially to the engine speed making it harder to map.

The nice steady 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 can help the brake cooling and are generally less heavy than steel ones. If you are serious about performance then you will need to carefully choose your tires - ideally with a soft compound tire. We should point out that although they can look cool on the Cultus Crescent / Esteem 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 with bigger wheels without problems we would restrict ourselves to a 17 inch rim size as the maximum.
