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.
