Toyota affiliated tuning design and race
engineering firm GRMN (Gazoo Racing Masters of Nürburgring) has revealed
a racing version of its GT86 sports coupe
dubbed the Sports FR Concept. It will make exhibited for the first time
at the 40th 24 Hours of Nürburgring endurance race which will be held
at the Nürburgring Circuit in the state of Rhineland-Palatinate,
Germany, from May 17 to 20.


Dramatically enhanced from the standard production version, the
Sports FR Concept features a 2.0-liter twincharged engine (turbocharger +
supercharger) that produces 320 HP (235 kW / 316 bhp) and 421 Nm (310
lb-ft) of torque via a 6-speed manual transmission. Other modifications
include GRMN suspension tuning with 18-inch racing wheels, GRMN brakes,
widebody kit with redesigned front and rear fascias, side skirts and
fenders, roll cage, stripped interior with racing bucket seats and
4-point harnesses, large rear spoiler and GRMN dual exhaust system.

Shame about the pretend LFA front bumper, other than that it sounds like a really interesting vehicle. Strange that they've gone for twincharging, though I guess they wanted to preserve thelinearityof the engine and give strong low end pull but with high peak performance as well.

I wonder how much higher the limiter can be pushed on the4U-GSE, If you got it up to 9000 with ~195Nm of torque still available (peak is 205Nm @ 6000rpm) you could achieve ~250bhp. Manage to up the torque by as little 10Nm (5%) and you'd "only" need to get to ~8200rpm for 250bhp. I'd say with some serious NA tuning to get 20-40Nm of extra torque and a modest increase to the limiter and you'd manage 250bhp without forced induction. You'd probably be getting to the reasonable limits there though and would have had to invest quite a lot of money/time.
