Peugeot 4007 Tuning

"Tuning guide to the greatest Peugeot 4007 modifications."

Based on the Mitsubishi Outlander the 4007 became Peugeot's compact crossover SUV. This was the first time a Japanese company became involved with a French car brand and it works really well.

It had a production run from 2007 to 2012 but sadly didn't meet the sales targets, probably due to a saturated market in this class of SUV and Peugeots relatively late arrival, which is a shame because it was a very well thought out car.

The 4007 is a good project car to carry out. Think carefully and research 4007 tuning to save yourself making the usual disastrous mistakes we come across.

Handling/Suspension upgrades

Handling modifications are high on most peoples lists for the 4007.

If you set the toe out to around 1.5 degrees on the front, and add some negative camber then cornering will radically improve.

Drop the car optimally somewhere in the region of 30mm - 38 mm and fit uprated stiffer dampers, bigger drops will need other modifications in most instances.

Power mods.

A nice wide torque band and sweet spot of peak power at one third of your RPM range is optimum.

Keep the car looking standard and take off the badges for the ultimate sleeper!
There were 3 engines offered.

• 2.4 L 4B12 i4 (petrol) 16 valve MIVEC I4, 170 PS *(a Mitsubishi unit)
• 2.2 L DW12 i4 (HDi diesel)  115 kW (156 PS), 380 Nm
• 2.0 1998cc 147ps version for the Russian market.

These are the sports upgrades are usually carried out by our members, decide how far you want to push your car before you begin.

Getting the correct grade of sports modifications for your planned usage of the car is a time and money saver. Stage 3 (competition) mods just don't work well on the road and will make the car undrivable.

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: Lighter flywheel, Panel air filter, Engine Tunes/Remapping, Suspension upgrade (drop 30-40mm), Sports exhaust, Alloy wheels.

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

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

Peak power is all well and good but for a drivable and fun car you need a long torque band and perhaps extending the rev range.

The whole aim of our advice is to give a starting base of modifying mods and point you in the right direction, our forum is best place to go if you need more detailed advice and tips on your car tuning project, the best sport parts and all aspects of modding cars.A fast road cam will be one of the best NASP power mods you can do with a single part fitted to your engine.

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 performance chip. TorqueCars would caution you not to go with a motor sport cam as this affects the engines idling and general town driving characteristics.

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

Most power losses, and erratic idling after performance mods are done can usually be traced to fuelling or timing issues.To get sufficient fuel you may need to uprate the injectors on your engine.

Uprate the fuel pump to cope with the extra fuel requirements of your tuned 4007s uprated injectors.

Intake and Exhaust Tuning.

Now we move on to the intake and exhaust and ensure proper flow through the engine. Induction kits only help to add performance if your air intake is struggling! Adding an induction kit to most low power engines will see ZERO LOW END POWER GAIN AT ALL.

If you have heavily modified your engine and it's need for air INCREASES DRAMATICALLY then an induction kit is the answer and will help remove this restriction.

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 increase the flow of air through the engine. But if the exhaust pipe is too large, ie: it's over 2.5 inches bore, you will lose much of the flow rate and end up sapping power and torque.

Head 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 seriously let you down 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 loss through the transmission. The best mods in our experience for your 4007 are Remapping or piggy back ecu, fast road cam and air intake and exhaustNA (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 seen some tuners toying with twincharging conversions and making some seriously high power gains.

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. It is harder to map a turbo as the boost increases exponentially with revs.

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 a lower unsprung weight and more efficient brake cooling via the extra air flow they allow.

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 4007, and make a big difference over budget tires.

The drawback to large alloys on your 4007 is that you're altering your final drive ratio so this will have a negative effect on performance.

Although some people have with bigger wheels we would stick to a 18 inch rim size as the maximum.
