The Japanese WRX takes the American-standard 2.0-liter, turbocharged, four-cylinder engine and ups the power to 269 horsepower and 295 lb-ft of torque, up from 268 horsepower and 258 lb-ft of torque. In the S4, power is sent through Subaru’s Sport Lineartronic continuously variable transmission to all four wheels.

Throughout the past few articles you’ve learned about the improvements we’ve made to the strength of the engine, and beefing up the fuel and cooling systems. This install we reveal why all of those modifications were necessary: forced induction.
One of the biggest let downs about the BRZ/FR-S was the lack of a turbocharged option. It seemed so simple, just pull the motor from the WRX and, voila, boost! Instead we were left with a car that, while well balanced, just wanted enthusiasts begging for more. Thankfully there is a healthy aftermarket that was practically frothing at the mouth at the opportunity to add forced induction.

As you recently read, we’ve completed modifying the cylinder heads and valve train to make sure the FA20 has sufficient and efficient breathing ability. In this installment, we’re going to pull back the curtain on what was done to modify the cooling, lubrication and fuel/spark systems to withstand the power and reliability we expect to achieve with this build.

Welcome back; it’s been a while! We’ve been hard at work getting down to business with our Pikes Peak Airstrip Attack and the Pikes Peak International Hill Climb, both part of the Pikes Peak Speed Week. While we were running around losing our minds, SCR Performance was hard at work making great progress with the BRZ build. Last time, we covered what it takes to build a bottom end stout enough to handle our power demands. This week we’re diving into the cylinder heads to see how SCR improved the breathing capacity of the FA20/4U-GSE.

Olympus Rally was held last weekend in Shelton, Washington. The event started with the announcement that Olympus Rally is officially a Rally America sanctioned event once more after a one-year break. Similar to the Oregon Trail Rally, the Olympus Rally offers extremely beautiful scenery, an assortment of obstacles, miles and miles of back roads and, most important, it has its NW Rally fans! It will be awesome to have Olympus on the national event roster next year giving the teams another event, and giving the sport yet another opportunity to expand and grow. Rally America seems to be doing all they can to help the sport evolve; they’re now nationally televised and in the process of adding other venues. We can’t wait to see what they produce next.
