Peugeot 4007 Tuning

"Thanks for reading my Peugeot 4007 tuning guide."

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

It was made from 2007 to 2012 and although it didn't meet the sales targets, it was still a good car, and this was probably due to an already saturated market in this class of SUV and the late arrival of Peugeots 4007.

The 4007 is a good car tuning project to execute. With the right mods your 4007 can be transformed into an awesome motor.

Don't waste money, do your homework and follow our unbiased guides to each performance upgrade to avoid disappointment.

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

With our guides your 4007 can become an awesome performer and be reliable daily driver.

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.

Engine Tuning.

The following sports modifications are usually carried out by our members, decide how far you want to push your car before you get going.

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.

Getting the right motorsport modifications for your planned usage of the car is vital. Stage 3 motor sport parts just won't work well on the road difficult in stop start traffic.

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

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

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

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

The whole aim of our guides is to give a brief overview of modifying upgrades and point you in the right direction, our forum is the place to go for detailed advice and tips on your customised car project, the best sport parts and all aspects of modding cars.A fast road camshaft is one of the best NASP power modifications you can do mechanically to your engine.

The intake and exhaust flow play a large part 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 remap to fully realise your gains.

When pushing up the power you will need to uprate to the fuelling. More power needs more fuel.

Using higher octane petrol is another option if you find you are suffering from detonation or premature ignition on your Peugeot project after fitting other modifications. Bigger injectors will enable you to supply sufficient fuel to the engine.

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. Air induction kits are only beneficial to add power if the cars air intake is restricted! 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.

For most 4007 engines TorqueCars would suggest you just go with a washable panel air filter. On heavily tuned engines and turbo vehicles an induction kit will help release the power providing you address the problem of supplying cold air.

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

Airflow through the head can be dramatically increased with some professional flowed (porting and polishing). These should match and be setup to take into account any other engine mods. A good triple plate fast road uprated clutch will help to keep that power going where it should. Never skimp or assume a standard clutch to cope. The best mods we would do for your 4007 are Remapping or piggy back ecu, fast road cam and air intake and exhaust.

Remaps offer phenomenal power gains on all turbo charged cars. On NASP engines the benefits are doubtful. However a remapped ECU on a NASP 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 usually easier to add than turbos. With a turbo the power curve is related exponentially to the engine speed making it more challenging to map.

The nice proportional boost and rpm characteristics of the supercharger make them more straighforward to map. To cope with forced induction you will usually need to decrease the compression ratio of the engine .

Handling/Suspension upgrades

Handling modifications are the thing most do first for the 4007.

If you set the toe out to 0.9 to 1.5 degrees on the front, and add a small amount of negative camber then cornering will greatly benefit.

Drop the car by as much as 22mm - 39 mm and fit motorsport grade stiffer dampers, bigger drops will need other modifications in most instances.

Alloy wheel upgrades.

Alloy wheels will help the brakes cool down and are usually less heavy than the steel ones. Get a good track legal slick tire to improve your handling and help improve traction on your 4007. Large 4007 alloy wheels can decrease performance. If you get big alloy wheels you will be changing your final drive ratio.

Although some people have gone larger than this we would stick to an 18 inch rim size as the maximum.
