Dear Calmotion , thank you for your compliment. My motor is a 2007 Subaru EJ253 2.5L SOHC flat 4 with variable cam lift. It was installed and built by Carey and mike at Special Edition. They started with a donor 2007 Subaru Impreza and use the ECU and drive by wire throttle and other engine parts. The heads are sent out and rebuilt. The other parts are powder coated to the color of your choice. They buy a new short block with warranty from Subaru America. The header is custom made by A1 in California. The transaxle is a Pro-Suby trans built new by Rancho with special gearing to match the Subaru power band. The engine and trans. are supported by a Kafer bar setup.The rear has a camber compensator but I don't run any sway bars. The cars seems not to need them it handles well and stays flat in hard cornering. The radiator is in the front and cools perfect. Never overheats even in 100 plus degree weather. Here are some pics.
