Hi All, am a new 500T owner (blue-green), and am wondering what are the differences that end up with 25 less hp than the Abarth? I know there's a different exhaust, but the specs show the same boost, bore, & stroke leading me to think it has the same turbo too. So where's the bottle-neck? I'm not looking to dump a bunch of money into my ride yet, but it's got me thinking.

My advance appreciation for your replies, Mike

The only power limiting difference is the exhaust (which is minor) and the computer tuning. The Turbo would be the exact same car performance wise if it was not electronically downtuned. You basically are paying for that computer when purchasing an Abarth. That and all the little bells and whistles (boost gauge, leather cluster, racing "inspired" seats, exhaust, suspension, limited slip diff, steering wheel, pedals, slightly larger spoiler). Also, post some pics of your car. I'd love to see a T in that color :)

Switch Intake, Exhaust and ECM.... Done.

Also... the ABARTH does not have a Limited Slip Differential.
The Transmissions are Identical between the ABARTH and 500T.

I thought the T has the smaller turning radius of the non Abarth 500.

That's an easy engineering change in the Hub Assembly.

The Transmissions are Identical between the ABARTH and 500T.You forgot shocks, springs, rear sway bar, 17 inch wheels and reinforced spring perches.

Does anyone know if you really can swap the ECU? And if you tried but didn't change the intake/exhaust, what bad thing(s) happen aside from maybe less power, quieter exhaust?

I was remotely aware of most of the differences, but the only one I've seen on the intake is the scorpion-badged intake cover. Is there something different underneath?
Also was wondering whether the MM ECU would make up for the rest of the difference, sans exhaust restrictions.
I don't have any good pics to post yet. just a kinda corny one taken by the "product specialist" and posted on vegasfiatgirl.com (great sales experience). I traded my 09 Prius in and am now LOVING driving.

i looked into the engine differences alot before buying the T, The only difference between the Abarth the T and the Dart engine is the software in the ecm. All three share the same block, internals, head, intake, turbo, down pipe and cat. I affirmed this with a cross check of part numbers. The exhaust on the T is not the restriction that people think it is. Tuned like an abarth i don't think the exhaust would cost you 5hp

My T only will boost 12psi max in sport i have never seen it go higher, the darts will boost as high as 20psi stock

I was only referring to getting the "Power" Output to match on each motor.

But if you want to get specific... the 17" Forged Wheels are NOT Standard on the US ABARTH, they are an option.

There are other "minor" differences across the model Line Up due to engine compartment sizing.

2013 (US) ABARTH 500
1.4L 16v Turbocharged
160 Horsepower
170 lb ft Torque

2013 FIAT 500T
1.4L 16v Turbocharged
135 Horsepower
150 lb ft Torque

The 500T is down 25 Horsepower/20 lb.ft. Torque.
That's not at all hard to get back with just an Intake, Exhaust, and ECM Swap.

The point is.... you can get the 500T to have the Same Power Output as an ABARTH.

But do the same things to the Abarth, and you get even more power. :)

This! :D

But thats not true from what i have been studying, technically if the abarth ecm works with a T it should make the same power, the reason the "boxs" will make less on a T is because the boost is set lower from the factory on the T. The problem is i'm not sure if the Abarth ecm will work in a T without other other modules being programed with Abarth software also. If someone had a spare abrth ecm i would be willing to try it in my T and let everyone know what happens
