The story

I picked up this car brand new in 2015. It was slowly modified and I competed in local autocross events through its first 5 years of ownership, while also being my daily driver. In 2018 I grenaded the rear differential and decided to do the STI drivetrain swap. Fast forward to 2023 and I spun a rod bearing on track at Nashville SuperSpeedway. After contemplating what to do next I made the decision to go dual port/direct injection with motec on a built FA20 block to target around 500whp with a conservative turbo to maintain low end powerband. As of today, the car is at Turn in Concepts in Cincinnati Ohio about to be tuned on Motec m142 w/c127 display, with tons of supporting modifications. I should be picking the car up very soon!!
