The Scion FR-S was just named the Hottest Sport Compact at the 2012 SEMA Show, and Toyota Racing Development (TRD) is apparently looking to make this car a little hotter. According to Car and Driver, TRD is close to coming up with a supercharger to fit to the car's 2.0-liter flat-four engine in order to squeeze out a little more performance. Currently, the FR-S produces 200 horsepower, but there's no guessing how much a supercharger could improve this figure.

With Subaru seemingly hard at work on a new turbo engine for the BRZ and even possibly a BRZ STI model, it is only logical for a force-fed FR-S to be in the works as well. Surprisingly, though, the report says that supercharger would be unique to the FR-S, but since the Scion and Subaru BRZ are mechanically identical, it isn't clear how this would be accomplished. TRD already offers plenty of upgrades for the FR-S such as exhaust, brake and suspension kits, and it offers a handful of superchargers for other models including the 5.7-liter V8 used in the Toyota Tundra and the 4.0-liter V6 used in the Tacoma.

      "Currently, the FR-S produces 200 horsepower, but there's no guessing how much a supercharger could improve this figure." TRD superchargers are typically around 6 psi in their other applications. Figuring that the other parts will remain stock, apart from the timing, I assume 20%-30% gain. For as light of a car as the FR-S, 250-260hp would be fun.

        I question whether they can run 6psi given the static compression ratio is 12.5:1.

          I should re-phrase. I question whether than they can run 6psi with a static compression ratio of 12.5:1 .....and pass durability validation testing required to offer this as a "doesn't affect your factory warranty" piece like the other TRD superchargers. I'm not saying they can't, just that it's a hurdle that would be easier to clear at 4.5 or 5 psi.

          You must not frequent FT86 forums...check the forced induction section where their are numerous kits pushing well over 350whp..reliably too 0_0

          So far this engine seems to be holding up well. It's already surpassed the limits of the factory clutch.

      This will be interesting if they go S/C route and Subaru goes Turbo. Will def help seperate the two models for those looking for more grunt than stock. That the it will renew the ever fun love fest debate of S/C vs. Turbo.

      As per World Challenge GTS class rules. In order for them to run a supercharger in that class they have to make it available to the public to buy. The race car will probably make around 300hp, the street version of the s/c will most like be 250 to 280

      Perfect. This is exactly what I was hoping would happen... Toyota would go the supercharger route, while Subaru would go turbocharging. This would be great in helping differentiating the 2 cars. Oh, and please guys, for the love of all that is holy, could you offer different rims for this car? Its not that the stock ones are ugly - they're actually pretty nice, but offering different rims is one of the absolute easiest ways to make cars look different, and yet both the BRZ and FR-S use the same exact design.

        Plus one on the different rims for the two cars.

      Everyone saw this coming. We all saw through the "chassis is perfectly matched to the power, any more power will make the car not work or feel right" bs the spokespeople said through their teeth. Everyone knows it needs more power. Everyone knows the chassis is incredible. Everyone knows with more power and more tire the car will be a performance steal. The only car that will rival a Turbo/SC 86 would be the new WRX and if Mitsu doesn't botch a new Evo. Maybe the new Mustang will also give similar power-to-performance as well with a true IRS and new lower weight. Of course, the Ariel Atom is still the performance steal, but that's not "really" a car. :)

      i never like the sound of a supercharged motor, i think the Brz sti would be my choice, im hoping for 300hp from that and brake upgrade so ill right them a check if its under 35k

      YES OMG YES. IF YOU ARE A REGULAR READER OF THIS BLOG THEN YOU MAY RECALL ME STATING WHEN ONE OF THE FIRST BLOG POSTS ABOUT THIS CAR CAME OUT THAT "TRD NEEDS TO MAKE A SUPERCHARGER KIT FOR THE FT-86/FR-S PRONTO!!" I stated "mark my words" in that post and explained why this would be a great idea for Toyota. I spoke about how power between 250-300 would make this car one of the most important Tuner/Purist cars of the CENTURY. And it looks like I am now an auto profit because these cars are already a MASSIVE hit as SEMA clearly has shown, and this official, factory approved system will sell by the thousands. It will be one of the most if not THE most successful after market part ever. Toyota can only benefit in many amazing ways the company has been lacking in in recent years. We need a rear-drive, light weight, quick car, and it's been provided. Now.... use this tech and maybe a new Supra could be emerging from Toyota's very conservative product portfolio mist.

        Why would you want a supercharger on that little displacement? Turbo, turbo, turbo...

        The only thing I remember reading is how you wanted to fabricate a 6 foot spoiler for yours out of tinfoil, and add a hockey card to the spokes so it sounds better.

      For the second model year, Subaru is producing their own direct injection-only fuel delivery and getting rid of Toyota's direct+port injection. This would alter the fuel delivery parameters in the ECU, making the two vehicles unique as far as aftermarket performance parts is concerned. It's thought that Subaru will be able to increase power through this optimized injection scheme. The spy shots of the Subaru BRZ STi clearly show the standard radiator behind the front grill, no intercooler to be seen. I highly doubt a forced-induction BRZ is in the works, even with the FA20 already given a turbo for the Forester and Legacy in Japan, as the chassis is totally different in the BRZ requiring a unique development for turbo placement.

        Highly doubt based on what? Every thing else seems to point to it being in the works.

          Get the car on a lift, you'll see there's no place for an aftermarket turbocharger to go without severe compromises to the exhaust flow path, resulting in back pressure on the valves and springs, hampering long-term reliability. Not to mention oil cooling issues in such a tight undercarriage. Sure, these things can be overcome by an OEM, but the price analysis is going to kill it, especially with the current exchange rate disadvantage for the US market and impending emissions regulations. As far as aftermarket turbos go, well who cares about reliability? (I'm talking 100,000 to the first tune-up, 60,000 mile warranty reliability. Not, "the turbo didn't explode" reliability.) I hope I'm wrong. I'd be the first in line for a 300 hp, $32k Subaru BRZ STi.

          You don't need room under the hood for a turbocharger ! You could use a remote turbo located in the trunk but I suspect new fenders,bumper, and hood will be developed by TRD and they will make it fit under the hood . They are an manufactor and subsideary of Toyota after all and not a tunner shop .

          The lead engineer has already said this car will never be, and was intended to be, turbocharged. Will there be higher power variants, sure. Could they change direction, also possible.

        Where the heck are you getting this info from?! Of course turbocharging is coming to the BRZ. That's not an IF, that's a WHEN. There is an absolute sh!t ton of room in the BRZ engine bay, and in fact tuner shops have already turbo'ed this engine. If some completely unconnected shop can do it, there is no reason the company that designed the car to begin with, couldn't do the same very easily. You make it sound like turbocharging an engine is some kind massive undertaking. A turbo'ed BRZ is coming... its just a matter of whether its going to be for next year, or the year after that (as a mid-cycle upgrade).

          @ graphikzking No one is saying that the OEM won't do a ton of ACTUAL engineering with a turbo set up (as opposed to tuner shops which will most just worry about things fitting), but the engine bay for this car has an ENORMOUS amount of room for the plumbing required. My WRX's engine bay doesn't have even remotely the same amount of room, even if all the plumbing for the turbo and intercooler were removed. Not even close. With how low that engine sits, they could put a top-mounted intercooler (like the WRX/STI engine), and still have a sh!t ton of room elsewhere to fit the turbo + hoses. And to keep from ruining the slick uninterrupted lines of the hood, I could see them mimicking what Mazda did with their last gen Mazda Speed6 and have a dual-layer hood which let air in from the grill but which still had the intercooler on top. Of course the manufacturer will be looking for reliability above all else, but for someone to say that a turbo model isn't coming is absurd. Its not going to have 400 HP and a million pounds of boost and be tuned from within an inch of its life, but some turbo variant with between 250-300 HP is a foregone conclusion.

          Tuner shops just look for room to put a turbo and throw it in there and run plumbing up/around anything everything to get it to work. OEM's do HOURS and HOURS of heat flow analysis making sure it won't overheat certain parts of the engine etc. I realize it can be done - but oems are MUCH more cautious in their approach. If an aftermarket pushes (just a wild example) 10lbs of boost and gets 280hp - it's more likely an OEM will only get 240hp and push like 5-6lbs of boost. They error on the side of caution. What works for you in your climate - might not work well on a hot texas drag strip/track race car. That's what the oem's have to factor in.

      Sigh. Ever since they started this project, all I ever wanted was 150HP in a RWD hatchback. But you can't please everyone.

        yeah, its not an ae86 revival. the internet forum-boys cant seem to understand that. its a 2000GT revival a cheap rwd hatch would have been pretty fantastic
