1957 Fiat 500 with Subaru STI power

fiat 1957 500 subaru sti
To many, the classic Fiat 500 might seem under-powered. It had a two-cylinder, 479CC, air-cooled engine that made twelve horsepower. Yes, only twelve horsepower. This was not much even in 1957. That is why companies such as Abarth had their way with the 500 and installed engines that made as much as 50 horsepower.
But here we are, many decades later. We are still hungry for power but in the mean time we have developed engines with substantially more horsepower per displacement. We’re all turbo-happy now because there is replacement for displacement, and it whistles. Now days one has many options of powering a classic such as the Fiat 500, with high output motorcycle engine probably making the most sense.
And yet here is a tiny Fiat 500 powered by a 300hp+ Subaru WRX STI engine. This is be beyond insane and it’s bordering on suicidal.

MotoeXotica Classic Cars rarely says “one of a kind”, but there just cant be another 1957 Fiat 500 Nuova like this one. This car was the subject of a ground up build by a meticulas owner who spared no expense in building this Fiat Performance MONSTER! It even has the aggressive stance of a Tarantula!
The Fiat 500 was a city car produced by the Italian manufacturer Fiat between 1957 and 1975. Launched as the Nuova 500 in July 1957, it was a cheap and practical town car. Measuring only 9 feet 9 inches long, and originally powered by an appropriately sized 479 cc two-cylinder, air-cooled engine, the 500 redefined the term “city car” and is considered one of the first city cars.
The body has been finished in a Fiat Light Ivory with “carbon fiber” vinyl striping to break up the solid white. The carbon fiber look continues on to the hood with the addition of stainless steel vinyl covering the hood held down by two rubber hood pins. A nice fitting black original equipped roll back convertible top is in great condition. To accommodate the larger wheels and tires, fiberglass fender flares are seamlessly attached. The basic chassis is all round-section tubed, while the engine/trans hoop is square section. Construction is well executed, with substantial looking tubing and a generally well-thought out layout. All the trim and is present and in good condition along with the both bumpers.
Inside, the pair of black vinyl sport seats with supportive bolstering replace the original seat. Black door panels and grey carpet complete the interior fabric. The original dash is complimented with all Auto-Meter Ultra-lite II backlit gauges, including a Auto-Meter speedometer mounted in the center of a four spoke Formuling steering wheel. EMS Stinger Engine Management system, with laptop programability and Greddy pro-fec b spec II boost controller. Keeping the engine cool, is an oversized C&R dual pass radiator with 3000 cfm computer controlled fan. A professionally built custom 10 point roll cage and set of street legal wheelie bars, keep everything safe.
This 1957 Fiat 500 Nuova project was completed by a single owner five years ago in Denver Colorado The car rides on a custom tube chassis with a ten-point roll cage. The engine is a 2.5 L Subaru EJ25 that has been upgraded with T3/T4 turbocharger, Bosch 500 injectors, and twin Pierburg fuel pumps. Running off a Greddy Profec B-spec II boost controller and an EMS Stinger ECU, the engine produces 300 horsepower to the wheels. The engine is connected to a Porsche G50 LSD transaxle via a Kennedy Engineered Products adapter and then is connected to a pair of Porsche 930 CV joints. Include with this car is an parts catalog, extensive collection of receipts and documents of this $14,700 ground up build, and that’s just hardware, that doesn’t even include the labor cost and knowledge to build this insane machine!
This Ivory Fiat 500 Nuova is an real attention grabber, whether it be on the drag strip or to show at events…GET OUT AND DRIVE!

    Glad the builder was meticulas, even if the seller isn’t.

      Meticulas, wasn’t he the Roman god of mechanical engineering?

    That must be a hairy little bitch to drive.

      It might be a little jumpy…

      Traction could be an issue.

        90lb. bags of cement in the nose could work wonders, at least at part-throttle.

    Back in March, I posted a Subaru powered Fiat 500 when Craigslist Crapshoot searched for drivetrain swaps, but the links are too old to work now.

    When a vehicle has a reproduction data plate stamped in the wrong font, incompletely filled out, and held in place with incorrect fasteners, perhaps this is one occasion when it’s not the best idea to include a closeup view in the listing.

        Engine and body numbers don’t match, but are close in sequence. Is that because the original body rusted out during production?

      Yeah, the DMV tends to frown upon that…

    My favourite WRX / STi drivetrain transplant used to be into a Brat.
    Used to be.

    Looks like it could give the Subaru “Firebug” a run for it’s money.

    Skip to 0:27 – that is what I thought of immediately on seeing this:

      Totally didn’t realize that was Hayao Miyazaki’s directorial debut. Now I’m off to pirate / watch it!

        Yep – and some of the footage (including the Fiat 500 sequences) was also reused in Stern Electronics’ 1983 laserdisc game Cliff Hanger. Some good car spotting in that game.
        Apologies for the window-in-a-window nature of the video; I couldn’t find video of a full playthrough on actual arcade hardware.

    I like the way the non standard “popped out” headlights make it looks like it’s been surprised from behind.

    1. RHParish Avatar

      Surprisingly, those were standard, to conform to US headlight regs. http://13252-presscdn-0-94.pagely.netdna-cdn.com/wp-content/uploads/eric/1959_Fiat_500_USA_For_Sale_Front.jpg
