Tuning the Fiat E.torQ and best E.torQ performance parts.
Best E.torQ upgrades
Just because particular parts are appear in lots of E.torQ projects it doesn't mean its worth having, so we'll best parts that will give your E.torQ the best power gain for you spend.
Significant gains on the E.torQ can be made from cam upgrades. Altering the cam profile alters the intake and exhaust durations on the engine and can dramatically change the bhp and power output.
Fast road cams usually bump the torque through the rpm band, you may sacrifice a little bottom end bhp but the high end rpm power will be better.
Competition cams, bump the high end rpm power band but as a result the car will not idle smoothly and low end power nearly always suffers.
A Competition cam won't do well if driving in heavy traffic.
You should ideally match your bhp range to your usage of the car so for a car driven daily stick with a shorter duration E.torQ cam
Different E.torQ engines respond better to different cam durations check your engine on a rolling road.
The engine timing and fuelling also will say much on the torque gains you'll achieve.
Extending exhaust or intake durations can alter the torque 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.

Best Engine Mods for your car
- Engine Tunes - engine tuning/remapping provides the most advantage in terms of cost savings, aftermarket ECUs, and piggyback ECUs are all alternatives.
- Fast road cams are one of the most significant mechanical changes, but they must be installed by someone who knows what they're doing and they are not always easy to source but you might find a local firm to regrind a stock camshaft.
- Intake and Exhaust - Note that on their own these mods will NOT ADD POWER in most cases, but they can help enhance power after other mods by removing the restriction.
- Upgrades to turbochargers and superchargers - forced induction is the most efficient approach to increase air supply, allowing you to burn more fuel and make more power. It is one of the most costly upgrades but provides the best gains.
- Head work - The goals of porting and flowing the head are to get air flowing into the engine while removing flow restrictions and turbulence.
- 58 PSI 340cc/min 200hp
- 58 PSI 511cc/min 300hp
- 58 PSI 285cc/min 200hp
- 58 PSI 426cc/min 300hp
- 58 PSI 312cc/min 200hp
- 58 PSI 468cc/min 300hp
Typical stage 1 mods often include:
Panel air filters, drilled & smoothed airbox, Fast road camshaft, Sports exhaust header/manifold, Intake manifolds, Remaps/piggy back ECU.
Typical stage 2 mods often include:
Fast road cam, fuel pump upgrades, high flow fuel injectors, Ported and polished head, induction kit, Sports catalyst & performance exhaust.
Typical stage 3 mods often include:
Internal engine upgrades (head flowing porting/bigger valves), Engine balancing & blueprinting, Competition cam, Adding or Upgrading forced induction (turbo/supercharger), Crank and Piston upgrades to alter compression, Twin charging conversions.
ECU flashing allows a tuner to release the full potential of all the upgrades you've done to your E.torQ.
(In some cases, as the factory ECU is locked flashing is not an option, so an aftermarket ECU is the route to take, and many of these will outperform factory ECU's but make sure it has knock protection and that you get it setup properly.)
It will usually give you around 30% more power on turbocharged vehicles and you can expect to see around 15% on NA (naturally aspirated) engines, but the end result often depend much on the upgrades you've done and the condition of your engine.
Forcing fuel and air into your E.torQ is the main goal to any engine performance tuning project.
Intake manifolds flow the air from the air cleaner and allow it to be sucked into the engine cylinders.
The size of bore and shape and rate of flow of the Air Intake manifolds can make a big improvement to fuel mixing and power on the E.torQ.
Many mass produced engine intake are needing motorsport parts, although some makers provide decently flowing intake.
Adding a E.torQ larger valve kit, getting E.torQ port enlargement and head flowing will also improve bhp, & more importantly will allow you to get an improved bhp increase on other upgrades.
E.torQ Turbo upgrades
NA (naturally aspirated) engines need quite a lot of work when you add a turbo, so we have a separate guide to help you take into account the pros and cons of going this route on your E.torQ
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 your motor has a turbocharger tuning mods are going to net you a larger power gain and you'll see that turbo charged engines are made using harder and stronger components.
There are weak spots for every engine, with some being over specified and some just sufficiently able to handle stock powerDiscover these limitations and fit stronger pistons, crank and engine components to cope with the power.
We've seen people spending a loads of money on turbo upgrades on the E.torQ only to watch the engine block catastrophically fail when it's been enthusiastically driven.
Larger capacity turbo units commonly suffer a bottom end lag, and smaller turbo units spool up much more quickly but do not have the top end engines power gains.
Thankfully the world of turbo units is always improving and we are seeing variable vane turbo units, allowing the vane angle is altered according to speed to lower lag and increase top end bhp and torque.
Twin scroll turbo units divert the exhaust gases into two channels and feed these at differently angled vanes in the turbo charger. They also help the scavenging effect of the engine.
You'll commonly see there's a limit in the air flow sensor (AFM/MAF/MAP) on the E.torQ when a lot more air is being fed into the engine.
You'll see that 4 bar air sensors coping with quite large power gains, whereas the OEM air sensor was restricting bhp at a much lower level.
Adding a supercharger or additional turbo will make large bhp and torque gains, although more difficult to configure. We have this article on twincharging if you want to read more.
Fuelling
You will need to ensure that the engine is not starved of fuel so will need to pay attention to the fuelling when you start going beyond 20% of a bhp and torque increase.
It makes sense to be generous with your flow rate on the injectors.
As a rule of thumb add 20% to the flow rate when buying an injector, which takes into account injector deterioration and gives you some spare capacity should the engine require more fuel.
We think this one is common sense, but you'll need to match your fuel injector to the type of fuel your car uses as well.
All the following flywheel power targets will assume an injector duty cycle of 80% and a base of 58psi of fuel pressure at idle.
4 Cylinder turbocharged engines
4 Cylinder NA (naturally aspirated) engines
4 Cylinder supercharged engines
E.torQ Performance Exhausts
You may need to improve your exhaust if your exhaust is actually causing a flow problem.
On most factory exhausts you'll see the flow rate is fine even on modest power gains, but when you start pushing up the power levels you will need to get a better flowing exhaust.
Sports exhausts can help equal out the flow of gases through the engine.
But if your exhaust is too large, ie: over 2.5 inches bore, you will lose a lot of the flow rate and end up sapping power and torque.
Typically exhaust restrictions are in the filters installed, so adding a faster flowing sports alternative is the answer. This keeps the car road legal and will flow much better due to it's higher internal surface area and design, so has the added benefit of keeping your car road legal. The alternative decat should be considered an off road only mod, as removing a catalyst is illegal in most territories and regions for road registered cars..
Weak spots, Issues & problem areas on the E.torQ
The E.torQ engines are generally reliable and solid units, as long as you follow the manufacturers service schedules, and use a good quality oil to ensure longevity. Few problems should happen as long as they are regularly serviced and maintained.
Carbon build up in the head, particularly around the valves which will sap power or create flat spots, this is a larger issue on direct injection engines but should be looked out for on all engines. We have tips on removing carbon build up.
Some of our members have had issues with flat spots or glitches after applying mods and upgrades or tuning, this is not usually related to this engines design, so instead see our article on diagnosing flat spots and problems after tuning which should help you get the bottom of this issue.
Regular oil changes are vital on the E.torQ, especially when tuned and will help extend the life and reliability of the engine.
