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.
With a bit of a lull as we wait for a few parts to show up for Project BRZ, we wanted to give a little extra insight into some of the processes employed by our partners during the build of the car. In this case, we got some great details on what SCR Performance does during the teardown and rebuild of an engine, specifically in regard to their experience with the Subaru EJ-series engines, which heavily applies to the FA20 / 4U-GSE.
And we’re back! Though Mother Nature didn’t cooperate for TX2K14, it didn’t dampen our spirits because we knew back home some good things were happening with Project BRZ. We’re back into the mix with our weekly documentary of the progress. To bring you up to speed, the engine is off to the machine shop where they can work their magic and we’re waiting on the remainder of the build’s components to arrive, including the widebody parts that we just finished up sourcing.
In this installment we crack open the box of our new Air Lift Performance Digital Combo Kit suspension and let you know what we found, compare and contrast to the stock suspension, and provide an initial assessment.
