Infiniti Q30 Tuning

"Cheers for reading my Infiniti Q30 tuning guide."

The Q30 is a awesome car tuning project to try. Think carefully and research Q30 tuning to avoid making the usual common slip ups we often hear people complain about.

Our aim here is to provide a guide to Q30 tuning and show the greatest modifications for your car.

Handling/Suspension upgrades

Improving the handling for DIY mechanics first priority in your Q30 tuning project.

 

Good suspension tweaks that greatly benefit handling for the Q30 include a couple of degrees negative camber and 1-1.5 degrees of toe (set out to improve cornering or in for better stability) on the front wheels.

We suggest that you fit sports suspension and lower the car by 21mm - 37 mm. Larger drops require arch work - especially on models already equipped with uprated suspension.

For greatly enhanced stopping you should get better high friction brake pads and match this with bigger discs.

We should point out that race brake pads will be noisy and will need to be hot before they are effective.

On your regular commute to work the brakes are only applied now and then and will not be effective so choose friction pads which have a low working temperature.

Top end power should be your overall aim on the Q30 with a nice fat peak torque band.

 

With our advice your Q30 can make some decent track times and yet still reliable daily run around.

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.

Tuning modifications.

These mods sports mods are usually carried out by our members, decide how far you want to go before you begin.

Getting the right motorsport modifications for your planned usage of the car is a time and money saver. Stage 3 motor sport mods just don't work well on the road hard to control in slow traffic.

Best Engine Mods for your car

  1. Engine Tunes - engine tuning/remapping provides the most advantage in terms of cost savings,  aftermarket ECUs, and piggyback ECUs are all alternatives.
  2. Fast road cams are one of the most significant mechanical changes, but they must be installed by someone who knows what they're doing and they are not always easy to source but you might find a local firm to regrind a stock camshaft.
  3. Intake and Exhaust - Note that on their own these mods will NOT ADD POWER in most cases, but they can help enhance power after other mods by removing the restriction.
  4. Upgrades to turbochargers and superchargers - forced induction is the most efficient approach to increase air supply, allowing you to burn more fuel and make more power. It is one of the most costly upgrades but provides the best gains.
  5. Head work - The goals of porting and flowing the head are to get air flowing into the engine while removing flow restrictions and turbulence.

Typical stage 1 mods often include: Alloy wheels, Engine Tunes/Remapping, Suspension upgrade (drop 21mm - 37 mm.), Sports exhaust, Panel air filter, Lighter flywheel.

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

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

You need to keep as much low end torque as possible and aim to achieve a long power band rather than a narrow top end power spike.

 

The whole aim of our advice is to give a starting base of tuning upgrades and point you in the right direction, our forum is the place to go for detailed advice and tips on your tuning project, the best tuning modifications and all aspects of modding cars.One of the biggest mechanical upgrades you can do to your NA (naturally aspirated) engine is to fit a fast road cam .

The exhaust and intake durations play a huge factor in your cars power band, but be careful here, getting this wrong can upset the idle and make the car impossible to drive in traffic. You'd need to follow a cam upgrade with other mods and finish with a tune/remap for the best performance gains.

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

If you find you suffer from flat spots and power surges after your performance mods you should check the fuelling and try a higher octane fuel as well. Upgrading the injectors is another beneficial modification and will deliver sufficient fuel.

Uprate the fuel pump to cope with the extra fuel requirements of your tuned Q30's uprated injectors.

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 a lot and are finding that the standard air intake has become limited.

Maximum power gains come from a full induction kit with a cold air feed on heavily tuned engines, this can be sited within an air box but a panel filter should suffice for most applications. TorqueCars suggest you use a panel air filter as these are easy to clean and maintain and generally perform better than paper ones.

Sports exhausts will certainly help air flow out of the engine but avoid an exhaust that is too wide or you could will reduce the flow rate. Stick to 1.5 to 2.5 inches as a rule of thumb.

gas flowing the head will allow you to maximise your air/fuel charge. Leave this to a professional though with a proper flow bench and machine tools In nearly all cases of Q30 tuning your clutch will start to suffer and this should be improved - read our tips on clutches for more information. The best mods we recommend for your Q30 are Remapping or piggy back ecu, fast road cam and air intake and exhaust.

Turbo engines are just crying out to be remapped. You will see impressive power gains on most modern turbo engined cars including diesels making a tune/remap one of the most cost effective and impressive modifications for your money.Despite the large cost involved adding forced induction to a NA (naturally aspirated) engine will give large power gains. Superchargers are generally easier to add than turbos. With a turbo the boost curve is related exponentially to the engine speed making it more challenging to map.

The nice steady boost and rpm characteristics of the supercharger make them easier to map. Adding forced induction will nearly always require a lower compression ratio or water injection.

Alloy wheel upgrades.

Because alloy wheels are lighter they improve performance and they help to cool the brake disks. Further improvements can be made to your cars handling with the addition of directional tread pattern tire. The drawback to large rims on your Q30 is that you're altering your final drive ratio and this will have a detrimental effect on performance and acceleration.

For this reason aim to keep the overall rolling diameter of the wheel your OEM settings. In all cases we do not recommend going above 18 inches.
