Infiniti Q60 Tuning

"Tuning guide to the greatest Infiniti Q60 modifications."

As many of our forum members have emailed us about the Q60 and recommendations on how to modify one, so we've put together this guide to go over what we feel are the primary areas which make for improvement and tuning success on this engine.

The Q60 is a lovely platform and came as a Coupe Convertible and Infiniti Performance Line (IPL) Convertible.

The range of engines chosen were fantastic making this an awesome project car to have. The key to Q60 tuning is finding the right mods you can waste loads of money if you do it wrong.

Low end torque, and more mid range are your aims for a Q60 modified to perfection.

 

Handling/Suspension upgrades

Improving the handling for most drivers, is rated as a top priority mod in your Q60 tuning project.

Adding slight negative camber on the fronts and around 1 to 1.7 degrees of toe (in for better stability or out to improve cornering), will often enhance your Q60 in handling and cornering.

We suggest that you fit uprated suspension and lower the car by 27mm - 35 mm. Larger drops require arch work - especially on models already equipped with uprated suspension.

For sharper improved stopping put better high friction brake pads and mate this with meatier brake discs.

We should point out that motorsport pads can grind and will have to be hot before they are effective.

On a road car the brakes are occasionally used, therefore won't be as effective at slowing you up so choose pads which don't need to be really hot.

Our aim in engine tuning should be to increase peak bhp at the top end.

To be completely frank and honest, on the more modest engine sizes you are wasting your time spending money on modifications, so if this applies to you get yourself an engine swap then apply the following mods.

Tuning modifications.

These mods tuning modifications are usually carried out by our members, decide how far you want to push your car before you start.

First generation (CV36, 2013–2015)

3.7 L VQ37HR 330 hp (250 kW)
3.7 L VQ37HR V6 348 hp (260 kW)

Second generation (CV37, 2017–present)

2.0 L M274 DE20 AL I4 (Europe, China, Canada, USA) 208 hp (155 kW)
3.0 L VR30DDTT twin-turbo V6 300 hp (220 kW)
3.0 L VR30DDTT twin-turbo V6 400 hp (300 kW) (Red Sport 400)

Getting the correct grade of tuning upgrades for your planned usage of the car is vital. Stage 3 motor sport parts just don't work well on the road making the car difficult to drive.

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, Suspension upgrade (drop 27mm - 35 mm.), Sports exhaust, Lighter flywheel, Engine Tunes/Remapping, Panel air filter.

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

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

Your targets when modding your car should be a wide torque range. You want to avoid sending all the torque to be at the top end unless you are creating a competition car.

 

In this article we shall give a little insight into the world to the best mods for your car, but we'd encourage you to spend some time on the site looking into the details of each type of performance mod.Fast road cams offer one of the biggest power gains for your money as far as a solitary motorsport upgrades goes on a NA (naturally aspirated) engine.

The exhaust & intake flow play a big role in your cars power band, but be careful here, getting this wrong can upset the idle and make the car awkward 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.

Don't forget to increase the fuelling when you are increasing the power - it makes the car more thirsty.

Frequently power losses, flat spots and erratic idling after motorsport mods are done can usually be traced to fuelling or timing issues. Increasing 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.

The next area for modification is the intake and exhaust.  Contrary to popular belief there is generally very little power gain reached by fitting an induction kit, they only help and are recommended after you increase the engines power to the point where the standard air intake box cannot cope!

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 performance 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 generally help improve air flow through the engine but do not go too wide or you could will reduce the flow rate. Stick to 1.5 to 2.5 inches as a rule of thumb.

flowed (porting and polishing) 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 Your clutch can lose you loads of power as you increase the power if it starts to weaken and the standard clutches are only ever good for power gains of up to 43%. Fit an upgraded clutch to avoid power losses through the transmission. The best mods we recommend for your Q60 are Remapping or piggy back ecu, fast road cam and air intake and exhaust.

Remaps offer significant power gains on all turbo charged cars. On NA (naturally aspirated) engines the benefits are doubtful. However a tune/remap on a NA (naturally aspirated) engine will help unleash the potential if you have done a lot of mods. Adding forced induction will see large power gains but this is usually too expensive to be cost effective. Superchargers are often easier to add than a turbo. It is harder to map a turbo as the boost builds exponentially with revs.

It is more straightforward to map a supercharger because the boost is directly proportional to engine speed on a linear curve. To cope with forced induction you will usually need to decrease the engines compression ratio .

Alloy wheel upgrades.

As alloy wheels are lighter they improve performance and they help to cool the brake disks. We can't go into too much detail here about tires but they are how the car puts the power down on the road so are a critical choice. track legal slick tires work well on Q60, and make a big difference over budget tires. Large Q60 alloys can decrease performance. If you get big alloys you will be changing your final drive ratio.

Although some people have gone larger than this without problems we would stick to a 18 inch rim size as the maximum.
