The JFA260 is our own Stage 3 turbo conversion for the Abarth 500, 595 and 695. It takes a standard 135bhp car to 260bhp and 375Nm on the stock engine internals, using a Turbo Technics S260 turbocharger that makes boost around 1,200rpm earlier than the usual Stage 3 kits, so it drives like a factory car rather than a laggy conversion. Kit supply, fitting and dyno calibration are all done in-house at JFA in Maidstone - get in touch and we will price it for your car.

The JFA260 conversion kit is a game changing performance upgrade for the Abarth. This full Stage 3 conversion kit will take a standard 135BHP car up to 260BHP or more whilst retaining full road legality – not compromising on emissions to make power. Due to the low weight of the Abarth, this boosts the power to weight ratio up towards that of vehicles such as the Lotus Exige, Jaguar XKR & Aston Martin DB9.
This really is the ideal fast road/trackday engine as it makes incredible power gains whilst retaining the cars superb OE driveability & reliability. Using a much more modern turbocharger than other kits currently on the market we’re able to produce boost 1200RPM earlier, reducing the turbo lag most Stage 3 conversions suffer from to a minimum.
This is the maximum safe level of power for the stock engine internals. The kit is capable of making 280+BHP with strengthened engine internals, with the turbocharger capable of over 300BHP. If at a later date you want yet more power, then it’s available without replacement of all the new parts you’ve just fitted.

Fitting
We generally advise allowing 12-14hrs to fit with a fully qualified technician.
We fit the kit in house at JFA. Get in touch for a fitting price and a slot in the workshop.
Tuning
Your Abarth will need re-tuning to be able to run correctly with the JFA260 kit fitted. The new 380cc injectors will need scaling in, and the new manifold pressure sensor, and charge pressure sensor will also need scaling in order for the engine to run correctly. You will also require the rear O2 sensor diagnostics disabling. If you don’t do this, you’ll get an EML for catalyst inefficiency.
JFA can fully tune the JFA260 kit in house on our Mustang dyno. Ask us for a price.

Questions we get asked
What is in the JFA260 kit?
Turbo Technics S260 turbo, four 380cc Bosch injectors, Bosch manifold and charge pressure sensors, 200-cell sports cat downpipe, Scorpion 2.5 inch exhaust, Forge front-mount intercooler and induction kit, silicone hoses, oil feed and return kit, gaskets, clamps, oil filter and two cans of Abarth 20W50.
Is the JFA260 road legal?
Yes. It keeps a 200-cell sports catalyst and the car passes its MOT; we do not make the power by removing emissions equipment.
Can it make more than 260bhp?
The turbo is good for over 300bhp. 260bhp is the safe limit on standard engine internals; with forged internals the same kit runs to 280bhp or more without replacing any of the parts you have already fitted.
How long does fitting take and can I fit it myself?
Allow 12 to 14 hours for a qualified technician. We fit it in-house - ask us for a fitting price. Whoever fits it, the car must then be tuned: the new injectors and sensors have to be scaled in and the rear O2 diagnostics disabled or you will get an engine light.
Which Abarths does it fit?
The 1.4 T-Jet in the Abarth 500, 595 and 695, including the Competizione and Turismo, and the Fiat 500 Abarth. Ask about the 124 Spider.
What does it feel like to drive?
Like a much bigger engine rather than a peaky one: boost from around 2,000rpm and a flat torque curve, with the factory driveability kept. The power-to-weight ratio ends up close to a Lotus Exige or an XKR.
