Factory power of the FRS was at around 133 WHP. After HKS Supercharger, upgraded fuel injectors, Cusco larger throttle body, exhaust manifold, invidia high flow catted downpipe and Koyo Racing Radiator were installed, the car made 229 WHP on 91 octane gas with Evans Waterless coolant and Tomioka Racing engine oil cooler for added cooling.

The whole engine upgrade package came next to build a stronger block and heads to support additional power. The engine block was sleeved with Darton MID with CP pistons and Carillo Connecting rods. All the case bolts and head studs were replaced with ARP for added strength.  The heads were equipped with Ferrea oversized valves, springs and retainers complete with custom port & polish for optimum flow on the heads. Flow testing shows a 15% flow improvement .With a fairly conservative tune on E85 fuel, the car achieved 301 whp and 219 lbs/ft on our Dynapack dyno. Tuning was performed using Ecutek which is the best tuning solution for BRZ/FRS FT86.

With meticulous tuning by Edwin Tang, we are achieving a car with great drivability and power with additional feature launch control, flat foot shifting, and auto blipping.
