Just recently, we announced that Scion was planning a friendly little competition for the 2012 SEMA Show. In this contest, Scion handed each of three tuners a 2013 Scion FR-S base model and a $15,000 budget. The task at hand: to build the most awesome FR-S inside of the $15K budget. For their work, Scion will hand over a $10,000 grand prize.

The unfortunate reality of this contest is that, like most SEMA cars, these three FR-S’ will likely be stripped and crushed just after the show, but we get to enjoy them for just a short amount of time. Scion has decided to let us in on the main specs of the three cars as we close in on the opening of SEMA, and one of these models is the “Carbon Stealth” FR-S by John Toca.

Scion’s release on this car indicates that John built this car to give you the practicality and enjoyment desired from a daily driver, but the ability to toss it around a track at the drop of a hat. So, is this custom-built Scion FR-S really up to snuff?

Click past the jump to find out.

Exterior

Toca went for the more-with-less look on the outside, as his FR-S has just enough custom work on the outside to make it unique, but not enough to overwhelm you. He began with a FiveAD 5-piece aero kit, which includes a front lip, side skirts and a pair of rear fascia ground effects. Up front Toca added in a new carbon-fiber hood with a hood scoop – no mention of it being functional or decorative – and a custom front fascia with LED lighting surrounding the air intake vents.

As you head down the side of Toca’s FR-S, you come across custom-built functional heat extractors near the rear of each front fender. You also get a set of APR GT carbon fiber side mirrors with a matte finish, which set atop thin pedestals. The roof also gets the customer carbon-fiber treatment, which definitely adds plenty of character to the factory FR-S’ natural good looks.

Around the backside, you get a massive carbon-fiber rear diffusor to help add a little more downforce to the FR-S’ body. Poking out from the underside of this diffusor is a pair of large tailpipes,

After adding all of this carbon fiber to the outside of the FR-S, Toca had the exterior coated in a custom-blended BASF R-M paint that he dubbed “Carizzma toca mocha.” Setting off this shade of beige are four Cor Cipher Max Concave custom 3-piece wheels, measuring 19-by-8.5 inches in the front and 19-by-10.5 inches in the rear. These rims are painted satin black with black diamond brushed inners and outers, and wrapped up in Pirelli Pzero tires, measuring 235/35R19 up front and235/30R19 in the rear.

Additionally, Toca had all of the FR-S’ lighting smoked out with bronze tint and had a custom liftgate handle with a blue Scion logo installed.

Interior

Unfortunately, Scion didn’t give us any pictures of this custom car’s interior yet, but it definitely sounds about as race-ready and functional as they come. Toca had a set of Recaro Sportster CS seats and track set sliders installed with Takata 4-point drift III black harnesses. Also keeping the riders inside the “Carbon Stealth” FR-S safe is a Cusco D1 chromoly 6-point roll cage.

The driver’s interface is modified via a Personal Grinta blue stitched leather steering wheel with Works Bell Black Rapfix quick release. Also adjusting the feel of driving this custom FR-S is its Perrin black shift knob. The shifter is surrounded by a custom cover featuring black leather with blue stitching. Matching this setup is a custom center console, featuring black leather with blue stitching.

The black with blue stitching motif carries onto the dashboard where the custom gauges are covered in the same black leather with blue stitching. Speaking of these custom gauges, they are Prosport Gauges EVO Series gauges and include: Volt, Air/Fuel, Boost, Oil Pressure, and Oil Temperature.

Completing the interior's look are leather front speaker housings with a ring to match the HVAC vents and silver trim around it, a headliner, pillars and door panels covered in black Alcantara with blue stitching, black leather rear seats, and carbon fiber dash inserts. Adding a little ambiance to the package is a custom trunk display with blue LED lights.

You didn’t really think the customizations would just stop at aesthetics, did you? Well, they do not, as Toca also upgraded the sound system in the base FR-S to add to its fun-to-drive factor. These upgrades include: a Soundstream 5-channel amp, two Soundstream 10-inch subs, Soundstream 100-watt, 6.5-inch, 3-way component speakers, Soundstream 100-watt, 5.25-inch, 2-way speakers, Soundstream 160-watt, 6.5-inch, 2-way components, Soundstream amp power capacitor, Soundstream farad hybrid super capacitor, Soundstream 7-inch LCD double DIN head unit, and custom plexi-tub sub enclosure.

Because this Scion is ready to run on the track at the drop of a hat, Toca made the subwoofer enclosure easy to remove prior to hopping on the track, because, as we all know, every pound makes a difference.

Engine and Drivetrain

Under the hood, you get the same Subaru-built, 2.0-liter, four-cylinder engine that you’ll find under the hood of any Scion FR-S. from the factory, this engine pumps out 200 horsepower at 7,000 rpm and 151 pound-feet of torque at 6,600 rpm. Toca strapped a Vortech V-3 H67 Supercharger with a billet impeller to the 2.0-liter powerplant and cooled the forced air via a Vortech Maxflow air-to-air intercooler. Helping keep airflow plentiful and restriction-free is an integrated oversized MAF housing and mandrel-bent aluminum charge duct.

Helping the exhaust escape the engine is a black powder-coated Borla cat-back exhaust system. Oddly enough, there is no mention of any exhaust upgrades prior to the catalytic converter, which is a shame. Adding a little more efficiency to the engine’s rotational force is a Perrin crank pulley. This will help it spin the supercharger at a quicker rate with less drag on the engine.

Unfortunately, Scion did not release the output numbers on the newly upgraded engine, but it likely will at the SEMA show. Depending on the boost level that Toca sets this supercharger system to, we estimate the FR-S “Carbon Stealth” at about 280 horsepower and 250 pound-feet of torque, with the torque curve shifting closer to the bottom end of the rpm range.

The drivetrain seems to be 100-percent stock, which will likely be confirmed at SEMA. This would mean that the engine hooks up to the base-level 6-speed manual transmission.

The factory FR-S hits 60 mph in 6.6 seconds and we can see the added torque significantly lowering this time, We are likely looking at somewhere in the 6.2-second range, maybe even sub-6 seconds.

Handling and Braking

Under the FR-S’s skin from the factory is a nice suspension system that affords its drive plenty of control and just a little bit of fun, thanks to its limited oversteer. Toca added in an AirRex air suspension system with a Viair 380C heavy duty compressor. To help reduce body roll, Toca had a set of front and rear strut bars from Cusco installed, plus front and rear Cusco power braces. A 20 mm Cusco anti-sway bar spans the FR-S’ front end and a 16 mm Cusco anti-sway bar covers the rear suspension, helping reduce the body roll even farther.

The aforementioned 6-point Cusco chromoly roll cage also adds to the body’s rigidity, making the FR-S handle a little better. Just for good measure, Toca added in a Cusco differential cover, which just adds a little flare to the FR-S’ undercarriage.

At the corners, the “Carbon Stealth” FR-S gets 8-piston KSport calipers painted Toca Mocha on the front and 4-piston KSport calipers on the rear. These calipers grip onto 356-by-32 mm (14.01-by-1.26-inch) KSport rotors and are fed through KSport carbon stainless-steel brake lines.

Conclusion

Unfortunately, we have to await SEMA’s opening before we get a first-person look at this and the other custom FR-S’. Scion was kind enough to give us a sneak peak here, but we really want to know what these models can actually do. Hopefully, Scion gave them a good once around a track, so we find out exactly how well-built these models are, instead of just going by who bolted on more garbage with their $15,000. We’ll see.
