By now, we’ve all seen photos of the Scion FR-S and the new 4U-GSE 2.0L boxer engine (from Subaru) complete with D-4S direct-injection technology. Simply stated, this engine is nothing like the EJ205/EJ257 powerplants we’ve been offered in the Subaru WRX and STI. The 4U-GSE four-cylinder engine has been engineered from the ground up. What about engine tunability, you ask? That’s an ultimate question the aftermarket world is dying to learn. Only time will tell; the FR-S and its newly introduced platform leave us with a plethora of questions that shroud us in a fog of mystery. Until the very first tuner shops begin tearing apart this engine, we’re salivating at the mouth of its true capability. With a mind-boggling 12.5:1 compression ratio and twin injectors, the 4U-GSE’s full power comes on at 7,000 rpm with 151 lb-ft of torque at 6,600 rpm.
Most recently, I returned from a short-term FR-S press event overseas to experience firsthand this truly amazing car. The fabled Scion concept cars and prototypes we’ve been teased with for over a year have finally emerged into budding reality with its release set to take place in the spring of 2013. During my excursion, I managed to uncover some interesting finds on the vehicle along with an opportunity to hot lap the vehicle on the Sodegaura Forest Raceway in Chiba, Japan.
As I type this column, a flurry of emails is being exchanged with the head engineer of the FR-S in preparation for an in-depth story in the upcoming May issue of 2NR. Forget the fluff pieces you’ve seen on random Internet sites. We’re bringing you a comprehensive story on the vehicle from a tuner’s perspective. Aftermarket wheel fitment, bolt-on turbocharger/supercharger, and upgradable OEM interior/exterior parts from Toyota are just a few items coming your way. Stay tuned!
