Improving air intake on the Fiat 2.0 twin cam tuning

You need fuel and air for an engine to work. If there is too little fuel then it will run lean, if there is not enough air it runs rich resulting in lost power . We'll pick up on fuelling later in this article but for now we shall look at air supply.

So the aim to any engine modification project to force air into your Fiat 2.0 twin cam tuning but this has a knock on effect with the air flow sensor.

It is not unusual that there is a restriction in the air flow sensor (AFM/MAF/MAP) on the Fiat 2.0 twin cam tuning when considerably more air is being drawn into the engine.

We note 4 bar air sensors coping with quite large power gains, whereas the OEM air sensor was restricting performance at a much lower level.

Air Intake manifolds flow the air during the suck phase from the filter and allow it to be drawn into the engine cylinders.

The bore size, shape and flow rate of the Air Intake manifolds can make a large improvement to fuel mixing and power on the Fiat 2.0 twin cam tuning.

Many mass produced engine intake are crying out for an upgrade, although a few manufacturers provide fairly well optimized intake.

Larger Fiat 2.0 twin cam tuning valves, doing a bit of port matching and head flowing will also improve power, and as an added benefit will allow you to get increasing the power increase on other parts.

Fiat 2.0 twin cam tuning performance cam tips.

Each engine responds better to less aggressive cam durations so set your engine up on a rolling road.

The ecu map and fuel pump and injectors also have an effect on the bhp gains you'll hit.

Extending exhaust or intake durations can alter the bhp band and on most engines the exhaust and intake durations do not need to match, although most cams and tuners use matched pairs there are some advantages to extending the intake or exhaust durations.

The cam profile plays a big part in the engines power output so cam upgrades make quite a large difference. The intake & exhaust durations will alter depending on the chosen cam profile, so large engines power gains are on offer for cam upgrades.

NB: Fast road camshafts normally raise the bhp and torque through the rev band, you could sacrifice a little low end torque but the top end will be higher.

Motorsport and race camshafts, raise the top end band but as a result the car will not idle smoothly and low end power nearly always suffers.

A Race cam won't do well if driving around busy urban areas.

You should ideally optimize your engines power to your typical driving style so for a road car stick with a shorter duration Fiat 2.0 twin cam tuning cam

Stage 1, 2 and 3 mods for the Fiat 2.0 twin cam tuning

Before we break the best tuning upgrades down into stages of tune, let's list the most effective tuning upgrades for you.

  1. Suspension Upgrades - always improve your cars handling
  2. Brake Upgrades - Even before adding power improve those brakes
  3. Intake - make sure the intake is not restricted, use filters and intake upgrades to improve this
  4. Exhaust - as with 3 ensure there is not restriction in the exhaust, cats are the usual bottleneck
  5. Tunes - remapping, piggyback ECU's and aftermarket ECU's can all make decent gains
  6. Fuelling - when you've increased power you'll need to match this with more fuel
  7. Turbo upgrades - Improving the intake with a large turbo and better flowing intercooler will be the biggest power gain you'll see (but one of the most complex).

This video guide to tuning cars is a great starting point to work from in your project.

Stage 1 Fiat 2.0 twin cam tuning parts:

Remaps/piggy back ECU, Panel air filters, Intake headers, Fast road camshaft, Drilled & smoothed airbox, Sports exhaust manifold.

Stage 2 Fiat 2.0 twin cam tuning parts:

Ported and polished head, Fast road cam, induction kit, Sports catalyst & performance exhaust, fuel pump upgrades, high flow fuel injectors.

Stage 3 Fiat 2.0 twin cam tuning parts:

Engine balancing & blueprinting, Twin charging conversions, Internal engine upgrades (head flowing porting/bigger valves), Competition cam, Adding or Upgrading forced induction (turbo/supercharger), Crank and Piston upgrades to alter compression.

The Fiat 2.0 twin cam tuning engines are fantastic to work on and thankfully there is a lot of modifications and tuning parts around.

Mapping should help to fully realize the full potential of all the parts you've done to your Fiat 2.0 twin cam tuning.

You will typically expect to see gains of approximately 20-30% more power on turbocharged vehicles and you can expect to see around 15% on NASP engines, but figures achieved usually differs on the parts you've applied and the condition of your engine.

Turbo modifications on the Fiat 2.0 twin cam tuning

To get a turbo working on a NASP engine there is a lot involved, from lowering compression ratio to improved fuel supply and mapping, so we have found a great guide to helpavoid the common pitfalls or end up with an unfinished project because you were not told what you were getting into by doing this on the Fiat 2.0 twin cam tuning.

The more air you can get into an engine, the more fuel it can burn and uprating the induction with a turbocharger upgrade makes superb power gains.

If the engine has forced induction parts are more reliable and you will discover turbo engines are made using strengthened components.

However you'll find engines will need better parts at higher power limits

See where you'll find these limitations and upgrade to better quality components to utilize the power.

It's not unheard of car owners spending a loads of money on turbo upgrades on the Fiat 2.0 twin cam tuning only to suffer the indignity of watching the car throw a rod soon after it's finished.

Large turbo chargers will usually suffer low end lag, and low capacity turbo chargers spool up quickly but won't have the high rpm torque gains.

Thanks to new tech the choice of turbochargers is always increasing and we are seeing variable vane turbochargers, allowing the vane profile is altered according to speed to lower lag and increase top end power.

Twin scroll turbochargers divert the exhaust flow into two channels and flow these at differently profiled vanes in the turbocharger. They also help the scavenging effect of the engine.

Beefing up the air intake by adding a supercharger or additional turbo will help you achieve very large bhp and torque gains, although harder to get working. We have this feature on twinchargers if you want to read more.

Tips about fuel supply on the Fiat 2.0 twin cam tuning

Don't forget to look at the fuel delivery when you are increasing the torque - it makes the car more thirsty. Most tuners we speak with say to be generous with your injector capacity.

The accepted safe increase is to add 15% when buying an injector, this allows for injector deterioration and affords you some spare capacity should the engine need more fuel.

Don't forget that different fuel grades will usually require different settings, a high octane fuel will burn more efficiently than lower octane fuel for example. A car will trim fuel supply to keep within the ideal air fuel mix but at the extreme ends you may need to adjust your injector capacity, or the mapping or you'll get flat spots and potential lean or rich fuel issues..

Recommended Fiat 2.0 twin cam tuning performance exhaust upgrades

We'd only recommend you look to replace your exhaust system with an upgraded one is if the existing exhaust is creating a restriction in flow.

On most factory exhausts you should find that the exhaust flow rate is fine even on modest power gains, but on a serious tuning project with a big boost in power you will certainly need to get a better flowing exhaust.

Sports exhausts generally help improve air flow from the engine but do not go too big or you may end up will reduce the flow rate. Stick to one and a half to two and half inches for best results.

Typically exhaust restrictions are traced to the emissions filters installed, so adding a better flowing high performance alternative will help avoid this restriction.

Decatting (NB:catalysts reduce harmful engine emissions) is illegal in most countries and regions.

Faults issues and things to look out for on the Fiat 2.0 twin cam tuning

Like most engines an Fiat 2.0 twin cam tuning, should have few issues if it gets properly serviced and looked after.

We cannot stress enough the need for oil changes with the correct grade of oil on the Fiat 2.0 twin cam tuning, failure to do this will exacerbate engine wear, on a tuned Fiat 2.0 twin cam tuning this is more important than ever and close attention should be paid to your maintenance schedule.
