Hyundai i30N Tuning Guide

The Hyundai i30N is a performance hatchback that offers an impressive balance of power, handling, and everyday usability. For many owners, however, the appeal doesn’t end with the factory settings. Tuning the i30N can unlock more performance and tailor the car to individual preferences. Whether you own a pre-facelift (2018-2020) or a facelifted (2020-2024) model, there are several tuning options available, but the differences in hardware and technology between the two mean that tuning them requires a tailored approach. This guide will break down tuning options for both pre-facelift and facelift models, focusing on “Stage Tuning” and hardware requirements, while also touching on potential legality issues for MOT purposes in the UK.

Section 1: Hyundai i30N Pre-Facelift (2018-2020) Tuning Guide

The pre-facelift Hyundai i30N, introduced in 2018, laid the foundation for what has become a highly regarded performance car. Owners of the 2018-2020 model can still enjoy significant tuning potential, but it’s important to understand the available options and the required components.

Stage 1 Tuning (ECU Remap)

The most common and simplest form of tuning for the pre-facelift i30N is a Stage 1 remap. This involves adjusting the car’s ECU to increase engine power, improve throttle response, and optimise fuel maps. Stage 1 is ideal for those who want a noticeable increase in performance without the need for additional hardware.

  • Expected Gains: A Stage 1 remap on the pre-facelift i30N can typically increase power by around 20-30bhp, bringing the total output closer to 290-300bhp.
  • Hardware Requirements: No additional hardware is necessary for Stage 1. The car’s existing parts, including the turbocharger, intercooler, and exhaust system, can handle the increase in power.
  • Legality Considerations: A Stage 1 remap usually remains within legal limits for the MOT, but it’s crucial to ensure that emissions remain within the legal threshold. 

Please note: Although no hardware is strictly required for Stage 1, you can install parts which do not require another ECU tune such as a K&N Performance Air Filter, or Scorpion i30N Cat-Back Exhaust system

Stage 2 Tuning (Intake, Exhaust, and Remap)

Stage 2 tuning typically involves further improving airflow through the engine with additional hardware upgrades. For the pre-facelift i30N, this means upgrading components like the intake system, intercooler, and exhaust.

  • Expected Gains: Stage 2 can provide a gain of 30-40bhp, taking the total output to around 310-320bhp, depending on the specific upgrades.
  • Hardware Requirements:
  • Legality Considerations: Stage 2 modifications can sometimes affect emissions, particularly if you replace the catalytic converter or fit a sports cat. In this case, the car may not pass its MOT if the emissions exceed the legal limits. Ensure any performance exhaust systems are homologated for road use.

Stage 3 Tuning (Turbo Upgrade and More)

Stage 3 tuning is typically aimed at owners looking for substantial performance gains and more extreme modifications. At this level, the i30N’s turbocharger is upgraded, and additional engine components are often required to cope with the higher power output.

  • Expected Gains: Stage 3 can result in gains of 60bhp or more, pushing the car’s power output to 340bhp or beyond, depending on the turbo and supporting modifications.
  • Hardware Requirements:
    • Bigger Turbocharger: To achieve substantial power gains, a larger turbo will be necessary.
    • Upgraded Fuel System: Higher flow injectors and a bigger fuel pump may be required to keep up with the increased fuel demand.
    • Stronger Engine Internals: Depending on the power output, stronger pistons, rods, and valves might be needed to prevent engine failure under higher boost.

Some owners have opted to fit aftermarket hybrid turbo options, some have chosen to go down the facelift i30N turbocharger route (higher peak gains) - be sure to consult with your chosen tuner before committing to a large purchase. 

Section 2: Hyundai i30N Facelift (2020-2024) Tuning Guide

The facelifted Hyundai i30N, launched in 2020, brought several updates to the car, including changes to the engine management system and the introduction of the 8-speed dual-clutch automatic (DCT) gearbox. These updates affect tuning, and the potential for performance gains can vary depending on the model.

Stage 1 Tuning (ECU Remap and Software Updates)

Just like the pre-facelift i30N, Stage 1 tuning for the facelifted model primarily involves an ECU remap. However, the introduction of the DCT in facelift models means some additional considerations regarding shift speeds and gearbox settings.

  • Expected Gains: A Stage 1 remap can increase power by around 20-30bhp, bringing the total output to around 290-300bhp.
  • Hardware Requirements: No hardware upgrades are needed for Stage 1 on facelift models.
  • Legality Considerations: As with the pre-facelift models, Stage 1 remaps typically remain legal for the MOT, provided the emissions are within the legal limits. Always verify that the remap doesn’t negatively affect emissions, especially with the introduction of the DCT, which may have slightly different emission characteristics than the manual.

Some owners will opt to add a few pieces of hardware that DO NOT require an additional tune to suit, such as the Forge Motorsport Induction Kit for i30N, Kona N & Veloster N

Stage 2 Tuning (Intake, Exhaust, Intercooler, and Remap)

Stage 2 tuning for the facelifted i30N is quite similar to the pre-facelift version, though the hardware may differ slightly due to the updated engine components and the introduction of the DCT.

Stage 3 Tuning (Turbo Upgrade, Fuel System, and Internal Components)

Stage 3 tuning for the facelifted i30N requires more significant modifications due to the need for higher performance hardware. The increased boost levels, especially with a larger turbo, will require supporting upgrades to prevent engine failure.

  • Expected Gains: Stage 3 can increase power by as much as 60-80bhp, resulting in a total output of over 350bhp, depending on the turbo and supporting modifications.
  • Hardware Requirements:
    • Larger Turbocharger: A bigger turbo will significantly increase power but requires proper tuning to ensure reliability.
    • Upgraded Fuel System: To support the increased power, a higher-flow fuel system (larger injectors and upgraded pump) will be needed.
    • Upgraded Internals: Depending on the power target, stronger engine internals like pistons, rods, and valves may be required to handle the higher stress.

Conclusion

Tuning the Hyundai i30N can significantly improve its performance, whether you own a pre-facelift or facelift model. The tuning options and hardware requirements differ slightly between the two, primarily due to the updates in the facelifted version, such as the DCT gearbox and updated engine components. Always ensure that any tuning modifications are road-legal and compatible with UK emissions regulations to avoid issues at the MOT. If in doubt, work with a reputable tuning specialist who can provide expert advice and help ensure your i30N stays within legal limits while still offering increased performance.
