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.

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.

Best Engine Mods for your car

Your feedback and input are invaluable in this process. If you've come across unique sources, stumbled upon hidden gems, or discovered effective methods for locating performance upgrade parts, your fellow enthusiasts would greatly appreciate hearing about them.

By sharing your knowledge, you contribute to the collective wisdom of the modification community.

Feel free to leave your thoughts, suggestions, and any sources you've uncovered in the comments below. Together, we can make the pursuit of performance upgrades on the Cultus a more informed and fulfilling journey for everyone.

1. Engine tuning or remapping stands out as the pinnacle of cost-effective enhancements for optimizing your vehicle's performance. This involves recalibrating the engine control unit (ECU) to fine-tune various parameters, delivering tangible gains in power, efficiency, and responsiveness. Alternatively, aftermarket ECUs and piggyback ECUs offer pathways to achieve similar results, offering flexibility in achieving your desired performance levels.
2. Fast road camshafts represent a mechanical transformation that carries substantial impact but is suited to older engines without variable valve timing mechanisms. However, their installation requires you entrust this task to a skilled professional. Despite potential sourcing challenges, local firms often offer services to regrind stock camshafts, providing tailored solutions for improved power delivery.
3. When considering intake and exhaust upgrades, it's important to recognize that these modifications may not independently generate power gains in most scenarios. Instead, their significance lies in their ability to reduce restrictions, effectively setting the stage for power enhancements after other modifications have been implemented.
4. Taking the leap into turbocharger and supercharger upgrades constitutes a substantial but highly rewarding investment. These forced induction systems stand as the most potent means to augment air supply, permitting greater fuel combustion and resulting in substantial power increases. While costlier than some modifications, the gains in performance are unparalleled.
5. Head work, encompassing processes like porting and flow optimization, serves a vital role in enhancing engine efficiency. The ultimate objectives include facilitating smoother air intake and minimizing turbulence within the cylinder head, leading to improved air-flow and combustion efficiency. This intricate modification contributes significantly to overall engine performance, often becoming a cornerstone for those seeking substantial power gains and efficiency improvements.

Typical stage 1 mods often include: Sports exhaust, Engine Tunes/Remapping, Alloy wheels, Panel air filter, Lighter flywheel, Suspension upgrade (drop 24mm - 44 mm.).

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

Typical stage 3 mods often include: 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 very well end up with a reduced flow rate. So generally speaking, keep 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 tune/remap especially on a turbo, a fast road camshaft and sports exhaust, with a good air intake.

NA (naturally aspirated) engines do not achieve big power gains if you tune/remap them, unless you have done extensive modifications. With turbocharged engines this is another story. A tuned/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 NA (naturally aspirated) 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.
