Fiat 500 1.2 Supercharger Kit
Tuning the Fiat 500.
"The Cheeky chic 500 is back"
The stunning Fiat 500 has managed to steal the hearts of 100000's. The diminutive Fiat is a perfect blend of retro and modern chic!
Of all the cars I have driven the Fiat 500 is the one that has you grinning from ear to ear.
It certainly isn't the fastest but it certainly rates as great fun thanks in part to its pin sharp handling and nippy little engines.
The 1.4 and the turbocharged Abarth are the models of choice for your tuning project, we have seen power figures on the Abarth approaching a positively silly 280bhp but we suggest you stick with a 200bhp ceiling or you sacrifice the handling and fun factor.
The Fiat 500 is pretty small and light so even the 1.2 engine responds well to a bit of tuning but obviously the larger the engine the greater the rewards.
For the ultimate sleeper you could get the 1.4 and swap in the Abarth engine and toys to have a super quick, standard looking 500.
A critic would suggest that it is probably easier to put standard trim on the Abarth but this is not as much fun and you still have to find a place for the intercooler to go ie the Abarth front bumper!
Handling/Suspension upgrades
Many 500 owners uprate the handling of their cars with sports suspension modifications as a priority, this will certainly increase your enjoyment of the car.
Good suspension tweaks that substantially benefit handling for the 500 include a couple of degrees negative camber and 1-1.5 degrees of toe (set out to improve cornering or in for better stability) on the front wheels.
We suggest that you fit sports suspension and lower the car by 25mm - 42 mm. Larger drops require arch work - especially on models already equipped with performance suspension.
For greatly enhanced stopping put better performance pads and match this with larger brake discs.
Please note that race brake pads will be noisy and will need to be hot before they bit.
On your regular commute to work the brakes are occasionally used, therefore won't be all that effective so choose pads which work well in daily use.
Top end power should be your overall aim with a nice fat wide peak torque band.
With our hints your 500 can be transformed into a track car and prove to be reliable daily driver.
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.
In standard form the Fiat 500 had us smiling from ear to ear, it certainly wins heart and looks stunning. When tuned the Fiat 500 is a totally new ball game and great fun track day car.
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 the 1.2 but there are not many donor 1.4 engines around.
Upgrade your pads to improve braking and reduce the risk of fade. Ferodo DS-2500 sports pads come recommended by TorqueCars Fiat 500 tuning members.
For better braking lose the drums on the rear (if fitted to your model) and get bigger discs all round. The 1.4T jet brakes is an easy upgrade for the smaller engined Fiat 500's.
Fiat 500 Tuning modifications.
These mods performance parts are usually installed by our members, decide how far you wish to go in your tuning project before you start.
Getting the right motorsport mods for your planned usage of the car is vital. Stage 3 motor sport mods just won't work well on the road difficult in stop start traffic.
Typical stage 1 mods often include:Suspension upgrade (drop 25mm - 42 mm.), Panel air filter, Lighter flywheel, Sports exhaust, Remap, Alloy wheels.
Typical stage 2 mods often include:Ported and polished head, Power/Sport clutch, high flow fuel injector, fuel pump upgrades, Fast road cam.
Typical stage 3 mods often include:Sports gearbox, Adding or upgrading forced induction (turbo/supercharger), Engine balancing, Internal engine upgrades (pistons/head/valves), Competition cam.
Peak power is all well and good but for a daily driven car you need a long torque band and perhaps extending the rev range.
The aim of our articles is to give a limited introduction of modifying upgrades and point you in the right direction, our forum is best place to go if you need more detailed advice and tips on your modified car project, the best motorsport modifications and all aspects of modding cars.Fast road cams offer one of the biggest torque gains for your money as far as a single modifications goes on a NASP engine.
It maximises the intake and exhaust flow and pushes up the power if done right. Ideally you'd add other mods and finish up with a reflashed ECU. We'd also caution you not to go with a motor sport cam as this upsets the engines idling and general town driving characteristics.
You will need to ensure that the engine is not starved of fuel so will need to look at the fuelling.
Most power losses, and erratic idling after kits are done can usually be traced to fuel delivery or timing issues.
Higher capacity injectors will enable you to supply sufficient fuel to the engine.
If you've uprated your fuelling with bigger injectors you will also need to get a bigger fuel pump to supply it.
Fiat 500 Intake and Exhaust mods.
The next area for modification is the intake and exhaust. For small Fiat 500 engine sizes go with a washable panel air filter.
On the 1.4 and turbo Abarth an induction kit will help increase power providing you address the problem of needing cold air but a panel filter still remains the staple option for most Fiat 500 tuning projects.
Sports exhausts will certainly help air flow through the engine but do not go too large or you will reduce the flow rate. Stick to 2.0 to 2.5 inches for best results.
Head work including a polish and port and 3 or 5 angle valve job will really help to release the potential of the engine.
When the time comes to replace the clutch on your 500 we suggest you get an uprated clutch and this will help transmit the power to the wheels.
Simple mods that most of our members have done include a decent exhaust system, a fast road cam, sports panel filter and remap should push the 1.4 engine to a credible 120/130bhp.
The same mods on the Abarth will push power to around 165bhp! Add a bigger turbo to the Arbarth and you will see power hitting around the 200bhp mark.
We have seen some impressive supercharger conversion kits for the Fiat 500 1.4 engine which, due to the lightness of the car, really transform the performance and is a good option if you want to create an Abarth beater from a standard NASP 1.4!
Superchargers boost power in proportion to engine speed so is easier to map and if you run a modest boost there is no need to mess around too much with the engines internals, just get the fuelling right.
If you want to run bigger boost on a forced induction setup then you will need to address the problems that will arise.
Decreasing the engines compression ratio will allow you to add forced induction, water injection may also help prevent detonation.
Fiat 500 Wheel modifications.
The benefits of alloy wheels include a lower unsprung weight and more efficient brake cooling.
The downside to large alloy wheels on your 500 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, the 1.2 will not be too happy with bigger and wider wheels though due to the lack of power and 17's may rub on the wishbone if you're not careful.
