Fiat Linea Tuning

"Thank you for reading this Fiat Linea tuning guide."

The Linea is a good car modification project to carry out. If you do your planning then you can create an awesome Linea but don't be fooled there are lots of kits out there that will simply not suit it read our unbiased guides first.

Top end power should be your overall aim on the Linea with a nice fat peak torque band.

Enjoy your Linea to the limit with our awesome modding tips - do the right mods in the right order.

Smaller engines do not provide much of a return in terms of power so start with a bigger engine. Engine swaps are a good option if you have a small engine size.

Engine Tuning.

Typically these performance mods are usually fitted by our members, decide how far you want to go before you get started.

Getting the best uprated mods for your planned usage of the car is a time and money saver. Stage 3 competition upgrades just don't work well on the road making the car difficult to drive.

Guide to the Best Tuning Mods & Upgrades

  1. Mods that Remove a Restriction

    If the intake or exhaust are restricted in any way this will have an impact on your cars performance, so use an induction kit/filter upgrade and better flowing exhaust whenever your tuning creates a flow restriction.

  2. Mods that Improve Handling

    Braking, Suspension and general alignment of the suspension components is vital for any tuning project even before you start increasing power.

  3. Fit Stronger Parts

    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.

  4. ECU Tunes & Remapping

    While some cars can be easily remapped, others may require piggyback ECU's or aftermarket ECU's but this is the most vital step of your tuning project as it fully releases the power from all of your mods and upgrades. Expect 10-20% on NASP engines and 30-40% on turbocharged units.

  5. More Power Needs More Fuel & Air

    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. Fuel to Air ratio is vital so upgrade the fuel pump & injectors. Also you can look to perform head mods (flowing and porting), bigger valves, fast road cams and forced induction upgrades to improve fuel.

Stages of Tune

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

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

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

Your aim when modding the engine should be a wide torque band. You don't want all the power to be at the top end unless you are creating a motor sport car.

In this article we shall give an overview and introduction to the best upgrades for your car, but we'd encourage you to spend some time on the site looking into the details of each type of performance modification.Fast road cams offer one of the biggest torque gains for your money as far as a single motorsport parts goes on a NASP engine.

The exhaust & intake 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 impossible 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.

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

Most power losses, flat spots and erratic idling after performance kits are done can usually be traced to fuel delivery or timing issues.Larger injectors will enable you to supply sufficient fuel to the engine.

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

Intake and Exhaust Tuning.

The next area for modification is the intake and exhaust. Contrary to popular belief there is usually a small power gain to be had by fitting an induction kit, they only help and are recommended after you boost the engines power to the point where the standard air intake box cannot cope!

Derestricting the flow of air into the engine is the primary part of tuning so get a freer flowing air filter if you find that the car is running lean only if you find the car is running lean. Induction kits can sound fun but due to the warm air in the engine bay they will not really increase power and more often than not rob you of power on most cars.

Do not go with the biggest exhaust you can buy this will slow up the exhaust flow rate - the best for power gains are usually between 1.5 to 2.5 inches. It is the shape and material more than the bore size.

Polishing and porting 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 When you tune up your Linea you will discover that the standard clutch starts to suffer so get an uprated clutch. The best mods in our opinion for your Linea are fast road camshaft, remap, induction and exhaust, suspension.

Turbo engines are just pleading to be remapped. You will see massive power gains on most modern turbo engined cars including diesels making a remap one of the most cost effective and massive modifications for your money.

We've also seen some tuners playing with twincharged conversions and making some impressively high power figures.

Adding forced induction will see big power gains but this is usually too expensive to be cost effective. Superchargers are generally easier to add than a turbo. Turbos provide boost in exponential proportion to rising engine speed and this can make mapping difficult.

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

Handling/Suspension upgrades

Many Linea owners uprate the handling of their cars with tuning suspension mods as a priority, this will certainly increase your enjoyment of the car.

Fully adjustable suspension allows you to fine tune the handling of you Linea often improving your drive.

Drop the car by as much as 24mm - 39 mm and fit performance stiffer dampers, bigger drops will need other modifications in most instances.

Alloy wheel upgrades.

The benefits of alloys include lowering your unsprung weight and better brake cooling via the extra air flow they allow. Get a good track legal slick tire to improve your handling and help improve traction on your Linea. Please note that although they can look cool on the Linea large alloys will actually decrease your performance. The larger you go the lower your acceleration will be - this to the change in your effective final drive ratio.

Due to this fact we would advise sticking to a maximum wheel size of 16 inches, although we know some of our members have fitted larger wheels with no problems.
