Peugeot 607 Tuning

"Tuning guide to the greatest Peugeot 607 modifications."

Aimed at the executive, luxury market the 607 was produced between 1999 and 2011 replacing the 605.

The handling is not up to Peugeots standards, but works fine on long motorway runs, where comfort is a priority, and this is an area we will address in this tuning guide.

The 607 is a good car tuning project to carry out. With the right mods your 607 can be transformed into a fun car. Don't waste money, do your homework and follow our unbiased guides to each performance upgrade to avoid wasting money.

Don't just look at the peak power figures, you need to see the whole torque curve when determining if a mod is right for you 607.

Enjoy your 607 to the full with our hot performance tuning advice - do the right mods in the right order.

Sadly with smaller 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.

Engine Tuning.

Typically these tuning mods are usually carried out by our members, decide how far you wish to go in your tuning project before you start.

Getting the correct grade of sports mods for your planned usage of the car is essential. Stage 3 motor sport parts just don't work well on the road and will make the car undrivable.

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

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

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

All the turbo engines are a dream to tune, and we really love the V6 engines, smooth and silky running and oodles of torque.

All diesel engines can be remapped for around 30% power hike, which is not insignificant considering the cost of a remap is around £300.

There were many engine options on the 607,

  • 2.0 16v (1997 cm3 EW10) 138 HP 140 lb-ft @ 4100 RPM
  • 2.2 litre (2230 cc) EW12160 PS 158 hp 160 lbf⋅ft
  • 2.9 litre (2946 cc) "3.0" ES9 V6, 211 PS 208 hp 218 lbf⋅ft
  • 3.0 V6 4AT 210HP @6000rpm 210 lb-ft @ 3750 RPM
  • 3.0 V6 5MT 210hp @6000rpm 210 lb-ft @ 3750 RPM
  • 2.0 litre (1997 cc) DW10 HDi Diesel 108 hp 160 lbf⋅ft–188 lbf⋅ft
  • 2.2 litre (2179 cc) DW12 HDi Diesel 134 hp 235 lbf⋅ft
  • 2.2 litre (2179 cc) DW12 HDi Diesel 168 hp 272 lbf⋅ft
  • 2.7 litre (2720 cc) HDi Diesel V6, 201 hp) 325 lbf⋅ft

 

You need to keep as much low end power as you can and aim for a long power band across the rev range rather than a narrow top end power spike.

In this article we shall give an overview and introduction 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 upgrade.One of the best mechanical motorsport upgrades you can do on your NASP engine is to fit a fast road cam .

The intake & 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 hard to drive in traffic. You'd need to follow a cam upgrade with other mods and finish with a reflashed ECU to fully release the power gain.

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

If you find you experience flat spots and surges after your performance modifications you should check the fuelling and try a higher octane fuel as well. To get sufficient fuel you may need to increase the injectors on your engine.

Uprate the fuel pump to cope with the extra fuel requirements of your tuned 607s uprated injectors.

Intake and Exhaust Tuning.

Breathing mods are usually next up. Contrary to popular belief there is generally a small if any power gain reached by fitting an induction kit, they only work well and are recommended after you raise the engines power to the point where the standard air intake box cannot cope!

Induction kits can work well on turbo engines and larger engines (if supplied with a suitable cold air feed or air box), generally though we'd just recommend for 607 engines you should just fit a performance panel air filter preferably made from cotton.

Sports exhausts will certainly help air flow out of the engine but do not go too big or you could will reduce the flow rate. Stick to 1.5 to 2.5 inches as a rule of thumb.

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 In nearly all cases of 607 tuning your clutch will start to complain and this needs an upgrade - read our tips on clutches for more information. The best mods that we recommend for your 607 are fast road camshaft, remap, induction and exhaust, suspension.

Remaps offer significant power gains on all turbo charged cars. On NASP engines the benefits are doubtful. However a remap on a NASP engine will help unleash the potential if you have done a lot of mods. The most phenomenal power gains for NASP engines usually involve the addition of forced induction. Superchargers are often easier to add than turbos. With a turbo the boost curve is related exponentially to the engine speed making it more challenging to map.

Superchargers however will give a boost which is directly proportional to engine speed so is simpler. To cope with forced induction you will usually need to decrease the engines compression ratio .

Handling/Suspension upgrades

Handling modifications are often a priority for the 607.

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

We suggest that you fit uprated suspension and lower the car by 30mm - 35 mm. Larger drops require arch work - especially on models already equipped with motorsport suspension.

Alloy wheel upgrades.

Because alloys are less heavy they improve performance and they help to cool the brake disks. Don't forget that your choice of rubber greatly affects your cars grip and handling. It is not worth compromising performance with cheap tyres when you can buy soft compound performance tires.The drawback to large alloy wheels on your 607 is that you alter your final drive ratio and this will have a detrimental effect on acceleration and performance.

Due to this endeavour to keep the overall rolling diameter of the wheel the same as supplied from the factory. In all cases avoid going above 16 inches.
