The stunning Fiat 500 has manageable to swipe the hearts of 100000's. The little Fiat is a perfect mixture of retro and modern cute ! Of all the cars I have encouraged the Fiat 500 is the one that has you grinning from ear to ear. It assuredly is not the fastest but it assuredly rates as large fun thanks in part to its pin sharp handling and agile little machines.
The 1.4 and the turbocharged Abarth are the models of choice for your tuning project, we have seen power figures on the Arbarth approaching a heartily foolish 280bhp but we recommend you stick with a 200bhp ceiling or you victimize the handling and fun element. The Fiat 500 is exactly small and light so even the 1.2 machine responds well to a bit of tuning but eminently the greater the machine the larger the rewards.
For the last-ditch slugabed you could get the 1.4 and swap in the Abarth engine and toys to have a super rapid, standard looking Fiat 500. A critic would recommend that it is possibly easier to put standard trim on the Arbarth but this is not as much pleasure and you still have to find a place for the intercooler to go ie the Abarth front bumper !
Fiat 500 Tuning modifications
You really need to keep as much low end power as you can and aim for a wide power band rather than a top end spike. Fast road cams offer one of the biggest performance gains as far as a bolt on part goes. Don't forget to uprate the fuelling when you are increasing the power - it makes the car more thirsty. Uprating the injectors is another beneficial modification and will deliver sufficient fuel. Uprate the fuel pump to cope with the extra fuel requirements of your tuned 500s uprated injectors.
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 17 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 you should really stick with 16's.
