Crystal White Pearl 2019 Subaru WRX STI S209 – Reliability Mods

Subaru | WRX STI : August 7, 2020

Our first S209 – one of the 209 USDM units produced – to come through the shop and hit the rollers!

Erik, the owner of this magnificent Crystal White Pearl 2019 Subaru WRX STI S209, is clearly a huge Subaru enthusiast, and is no stranger to modifying the platform. So, naturally, he had a few key modifications in mind for both improved performance and reliability.

After everyone was done snapping their personal pictures, John strapped her down to the rollers for baseline dyno pulls to establish our starting point, coming in at a strong 303.88awhp & 298.16lbft, with the HKS turbocharger delivering 18psi.

From there, we installed a Street Series air/oil separator from IAG Performance, along with a cylinder 4 chamber cooling system from Getadomtune, and from there, she went back to the rollers to get flashed with a Stage-1 OTS map via COBB Tuning’s V3 Accessport. The result? Output increased to 330.95awhp & 328.08lbft, a gain of 27.07awhp & 29.92lbft! Stay tuned for more to come from this gorgeous S209!
