Last project car was a 2008 Yaris and loved it. Every bit of it.
First mod was a TRD catback and intake. Then came wheels, tires and megan coils. With all the N/A mods the car topped out on the dyno at a whopping 112 whp. Next was a custom built turbo kit tuned on AEM FIC. Dyno was now 188whp. After a year I started to lose compression in the engine due to burnt valves from a bad tune. So that meant a built engine which at the end I got it up to 280 whp and 260wtq from a disco potato (GT2860RS). Running that turbo with an open downpipe the car sounded like a semi truck. All you could hear is the turbo spooling over everything else. I smelled like gas all the time

Car weighed ~2500 with me in it.
Lots of power was still left on the table but when I saw the BRZ I had to have it. It is my first RWD car and I always wanted to see what the hype was about.
