From the owner
I purchased my 2015 Scion FR-S July 4th, 2014 by accident. I always knew I was going to get a track car and I wanted something light, quick, and reliable. After I finally settled on a 2014 FR-S, we discovered while doing the purchase paperwork that the Vin number associated with the car that I chose was registered as a 2015. It was the first 2015 in the state and one of the very first in the country. This came as a pleasant surprise because I knew they updated the suspension on the 2015 model and improved the handling. Back to back comparison of a 2014 vs 2015 confirmed it.
Regardlees, my mindset was, it's easy to add power, but hard to remove weight. So I decided to buy this car and turbocharge it. I figured, "brand new Subaru engine platform... They WILL turbo it in something, so it will be sturdy enough to turbo it." and I was right (ie 2015 subaru wrx). The first thing I focused on where wheels, tires, brakes, and life support mods. I needed to make sure the car would survive a track day. I bought the brake components, 1 of my 2 catch cans, and a Mishimoto oil cooler (I've since sold it for a different style). That setup worked great for the track but when I got to forced induction my plans took a slight change. I decided to supercharge the car instead of turbo because I too had discovered this thing called autocross. It was originally going to be a passing fancy. Something fun to do that I wouldn't take seriously. But I had a blast and got hooked. Turbo lag, 350 whp, and a 2700 lb RWD sports car do not mix well with autocross, so I opted for the response and more precise control ability of a supercharger. The intercooler it came with prohibited the continued use of my oil cooler, so I got the dual radiator oil cooler from Jackson Racing which uses a water/oil laminova style cooler. This car in its current configuration has run a 1:25 lap time at Roebling with the Porsche Club of America and it matched the lap time of a black group 2016 Porsche 911 GT-3 RS
