MENUPeugeot 107 Tuning
"Time the baby 107 grows up!"
The little 107 is a favourite project car. It's generally cheap to insure and popular with young drivers and as a result of this there are lots of performance parts around for them.
You must choose your mods wisely though, we frequently hear of 107 owners who have lost all low down power, experience misfires or flat spots and have starting problems after they have added the wrong mods.
We'll look at the best mods for your 107 and blow a few of the commonly held myths out of the water allowing you to focus on the mods that will really make a difference to your performance.
Many 107 owners uprate the handling of their cars as a priority, this will certainly increase your enjoyment of the car. Drop the car by as much as 40mm and fit stiffer dampers, bigger drops will need other modifications in most instances.
Our aim in 107 engine tuning should be to increase peak power and Torque at the top end.
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.
This list of the stages and mods that are usually performed by our members, decide how far you wish to go in your tuning project before you begin.

Guide to the best 107 tuning mods & Upgrades
- ECU Map Tuning & Remaps
Some cars may require a piggyback ECU's or aftermarket ECU's to change the OEM map, but remapping is the most vital step of your tuning project to fully maximise your mods. Expect 10-20% on NASP engines and 30-40% on turbocharged units.
- Strengthen Your Engine
Tuned cars will show up weaknesses, typically in the turbochargers, clutch and internal engine components. Whilst most engines can cope with mild tuning mods, TorqueCars recommend that you upgrade the internal components before these weak spots manifest themselves.
- Mods that Remove a Restriction
A restricted intake or exhaust will have an impact on your performance, so use a better flowing air filter/induction kit and better flowing exhaust (sports cats where legal are a good option) whenever your tuning creates a flow restriction. Turbo engines also benefit from intercooler upgrades as these resist heat soak for longer periods of time.
- Mods that Improve Fuelling
Every tuning project will aim to increase the air supply, but fuel supply is just as vital and will need to match the air the engine can utilise, a fuel pump and injector upgrade are usual mods, but also in many cases the fuel regulator will need improvement.
- Mods to Provide better Airflow
Increasing the air supply is just as essential as improving fuelling, we suggest you look at head mods (flowing and porting, 5 angle valve jobs), fit bigger valves, fast road cams and forced induction upgrades (adding a better flowing turbo) to improve air intake.
107 Engine Tuning.
Getting the right mods for your planned usage of the car is a time and money saver. Stage 3 (competition) mods just won't work well on the road making the car difficult to drive.
Stage 1 mods:sports exhaust,lighter flywheel,Panel air filter,Remap,alloy wheels,suspension upgrade (drop 30-40mm).
Stage 2 mods:power clutch,Ported and polished head,Fast road cam,fuel injector & fuel pump upgrades,.
Stage 3 mods:sports gearbox,Internal engine upgrades (pistons/head/valves),Engine balancing, competition cam,adding or upgrading forced induction (turbo/supercharger).
Your goal when tuning the engine should be a wide torque curve. You don't want all the torque to be at the top end unless you are creating a motorsport car. In this article we shall give your a good starting base 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.
The intake and exhaust durations 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 camshaft upgrade with other mods and finish with a performance chip to fully realise your gains.Don't forget to uprate the fuelling when you are increasing the power - it makes the car more thirsty.
Using higher octane petrol is another option if you find you are suffering from pinking or premature ignition on your Peugeot project after fitting other modifications. Uprated 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.
Now we move on to the intake and exhaust and ensure proper flow through the engine. Contrary to popular belief there is usually very little power gain to be had by fitting an induction kit, they only work well and are recommended after you increase 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 107 engines you should go with a performance panel air filter prefereble made from cotton.
Do not go with the biggest exhaust you can get this will slow up the exhaust flow rate - the best for power gains are usually between 1.5 to 2.0 inches. It is the shape and material more than the bore size.
Getting the polished and ported will further help more air into each cylinder. This is definitely a job for a professional with a flow bench. A good triple plate fast road performance clutch will help to keep that power going where it should. Never skimp or expect your standard OEM clutch to cope. NASP engines do not achieve big power gains if you remap them, unless you have done extensive modifications. With turbocharged engines this is another story.
A remapped turbo will give significant power gains and fully release the potential power of the engine. Despite the large cost involved adding forced induction to a NASP engine will give large power gains. Turbos are generally harder to add than a supercharger. Turbos give boost in exponential proportion to increasing engine speed and this can make mapping difficult. The nice steady boost to rpm characteristics of the supercharger make them easier to map. To cope with forced induction you will usually need to decrease the compression ratio of the engine.
Alloy wheel upgrades.
The benefits of alloy wheels include a lower unsprung weight and more efficient brake cooling. The downside to large alloy wheels on your 107 is that you alter your effective final drive ratio and this will have a detrimental effect on acceleration and performance. Although some people have gone larger we would stick to a 16 inch rim size as the maximum.
