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.
