Nissan Juke Tuning

"Tuning the Nissan Juke and best Juke performance parts."

Rather than wait for a Nismo conversion you can do much to tune and modify your Nissan Duke. Nissan Jukes are generally very good project cars and with a few sensible performance upgrades you can dramatically maximise your driving experience.

We see many people wasting money on their Juke doing the wrong mods and then having to start over. Follow our tips to avoid making the common mistakes

Handling modifications are usually your first port of call for the Juke. Drop the car by as much as 35mm and fit stiffer dampers, bigger drops will need other modifications in most instances.

Our aim in Juke engine tuning should be to increase peak power and Torque at the top end. Drop in a GTR engine conversion for the Ultimate power hike! (Not a mod for the faint hearted!)

With our recommended mods you can turn your Juke into a fun car, beating bigger engined cars on the track.

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. Turbo engines respond well to remaps and you have the options of turbo upgrades on them.

Power mods.

This list of the stages and mods that are usually performed by our members, decide how far you wish to go in your tuning project before you get going.

Getting the right mods for your planned usage of the car is vital. Stage 3 motorsport parts just don't work well on the road making the car difficult to drive.

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

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

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

You really need to keep as much low end power as possible and aim for a wide power band across the rev range rather than a narrow top end power spike. The whole point of this article is to give a starting base of car tuning 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 project and all aspects of modding cars.

One of the most cost effective mechanical mods you can do on your NASP engine is to fit a fast road cam .

It maximises the intake and exhaust flow and pushes up the power if done right. Ideally you'd add other mods and finish up with a remap. TorqueCars would caution you not to go with a motor sports profile cam as this upsets the engines idling and general town driving characteristics.When pushing up the power you will need to pay attention to the fuelling. More power needs more fuel.

Frequently power losses, and erratic idling after mods are done can usually be traced to fuelling or timing issues.Uprating the injectors is another beneficial modification and will deliver sufficient fuel. 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 power gain to be had by fitting an induction kit, they only become beneficial and are recommended after you increase the engines power to the point where the standard air intake box cannot cope!

Derestricting the airflow into the engine is the primary part of performance tuning so get a better flowing air filter if you find that the car is running lean. Induction kits can sound great but due to the warm air in the engine bay they will not really increase power and usually rob you of power.

Sports exhausts increase 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 your flow rate and end up sapping power and torque.

Getting a professionally flowed (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 skimp or expect the standard clutch to cope.

Remaps offer large power gains on all turbo charged cars. On NASP engines the benefits are doubtful. However a chipped ECU on a NASP engine will help unleash the potential if you have done a lot of mods. The most phenomenal power gains for NASP engines usually involve the addition of forced induction. Superchargers are generally easier to add than a turbo.

It is difficult to map fuelling with a turbo as the boost comes on exponentially with rpm. The nice proportional boost and rpm characteristics of the supercharger make them simpler to map. Adding forced induction will often require a lower compression ratio or water injection.

Alloy wheel upgrades.

The benefits of alloy wheels include reducing your unsprung weight and better brake cooling. Large Juke alloys can decrease performance. If you get big alloys you will be changing your final drive ratio. Due to this we would advise sticking to a maximum wheel size of 18 inches, although we know some of our members have fitted larger wheels with no problems. Chunkier tyres can do much to enhance the appearance and stance of the Duke but we acknowledge this is down to personal taste.
