Megane tuning guide

"Thanks for reading our Renault Megane tuning guide."

With every iteration of the Megane Renault builds on the driveability of the previous putting the Megane at the top of many drivers car buying lists.

We examine the options for your Megane tuning and summarise the ultimate modifications for your car. Renault Meganes are awesome to work on and with carefully picked performance parts you can definitely increase your driving enjoyment.

First let's look at the Meganes history.

It was first released in 1995 and this mk1 version was produced up to 2002. Unusually Renault provided a performance model from early on and the 2.0 Turbo was the tuners favourite back then.

This offers around 165 bhp in standard form. With the aid of some breathing mods, a progressive boost controller, a bit of modified timing you could make the car a very solid performer indeed.

There were a number of reliability issues on the early meganes but most enthusiastic owners will have uprated the weak spots and sorted these out.

In 2002 the Renault designer's had a field day and remodelled the entire layout of the Megane and even gave it a cute backside.

The styling was not to everyones taste but the overall package was good and there were certainly plenty of options and nice touches causing it to win a car of the year award.

It also got a NCAP rating of 5 stars making it one of the safest cars around in the 2002 model year.

More recent revisions have resolved the styling of the 2002 and a new Megane, looks quite modern and sporty compared to the Mk1.

Handling/Suspension upgrades

Improving the handling for DIY mechanics first priority in your Megane tuning project.Fully adjustable suspension allows you to fine tune the handling of you Megane substantially improving your drive.

Drop the car by as much as 22mm - 40 mm and fit sports stiffer dampers, bigger drops will need other modifications in most instances.

Sourcing parts from the Megane Sport model can be a good shortcut to low cost performance mods.

These are the sports upgrades that are usually installed by our members, decide how far you wish to go in your tuning project before you get going.

Getting the correct grade of modified modifications for your planned usage of the car is essential. Stage 3 motor sport mods just don't work well on the road making the car difficult to drive.

Typical stage 1 mods often include: Sports exhaust, Suspension upgrade (drop 22mm - 44 mm.), Lighter flywheel, Alloy wheels, Panel air filter, Remap.

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

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

Your aim when tuning should be a wide torque band. You don't want all the torque to be at the top end of the rev range unless you are creating a competition car.

The whole point of our guides is to give a brief overview of modding mods and point you in the right direction, our forum is the place to go for detailed advice and tips on your car tuning project, the best modified upgrades and all aspects of modding cars.

Fast road cams offer one of the biggest performance gains for your money as far as a bolt on performance upgrades goes on a NASP engine.

It improves the intake and exhaust flow and increases the power if done right. Ideally you'd add other mods and finish up with a performance chip. We'd also caution you not to go with a competition cam as this affects the engines idling and general town driving characteristics.

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

If you find you suffer from flat spots and surges after your motorsport mods you should check the fuelling and try a higher octane fuel as well. Upgraded 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.

Alloy wheel upgrades.

Alloy wheels will help the brake cooling and are generally lighter than the steel ones. 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 track legal slick performance tires.Large Megane alloys can decrease performance. If you get big alloys you will be changing your final drive ratio.

Although some people have installed larger rims without problems we would restrict ourselves to a 18 inch rim size as the maximum  - we would stick to 17inch rims on the early Meganes because you'll need to roll the arches and modify the suspension to cope with it.

Handling/Suspension upgrades

Handling modifications are a good place to start for the Megane.

The next modifications for the Megane include revised suspension although the RS suspension is actually nicely fettled for road use. On the larger engine sizes an induction kit, sports exhaust and sports car will lift power. Adding some fast road cams will also improve the mid and top end of the rev range.

If you set the toe out to 0.9 to 1.5 degrees on the front, and add slight negative camber then cornering will usually improve.

We would go to a maximum drop of 22mm - 44 mm. on most models. You risk rubbing on the arches if you go lower than this.

Intake and exhaust modifications.

Breathing mods are usually easily sorted and probably one of the easiest mods to do. For smaller engined Megane projects go with a high flow sports panel air filter.

On cars which have had a massive power hike, an induction kit will help increase the peak power providing you address the problem of it sucking in warm engine bay air by using a cold air. The standard Megane airbox flows quite well so there is no practical reason to add an induction kit for most tuning projects.

A good high performance sports exhaust is an essential to balance your engines need for free flowing air, and while you are at it you should add a sports catalyst as well.

Please read our article on performance exhausts for details of the issues around large bore exhaust flow rates and how to choose the right size for your engine.

Head work including a polish and port and 3 or 5 angle valve job will really help to release the potential of the engine.

A good quality multi plate fast road power clutch will help to keep that power going where it should.

Being front wheel drive, the Megane benefits greatly from a torsion differential, especially during heavy cornering or in the wet. It really helps put the power down.

Never just hope that a standard worn clutch will cope if you have an ambitious tuning project. 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. Despite the large cost involved adding forced induction to a NASP engine will give large power gains. It is easier to bolt on a supercharger than it is to get a turbo working.

With a turbo the boost curve is related exponentially to the engine speed making it hard to map. The nice steady boost to rpm characteristics of the supercharger make them easier to map. Adding forced induction will usually require a lower compression ratio or water injection.
