Cosworth recently announced that it will begin offering power upgrade kits, rather than individual performance parts, for the popular Scion FR-S and Subaru BRZ sister cars in order to drastically boost power and maintain stock reliability. The first of the kits – the FA20 Stage 1 Power Package – is currently available for purchase and will bump performance to a forceful 230-horsepower.

Stage 1 overhauls the car’s respiration and includes a free flow sports exhaust with diagonally cut tips, a Y-shaped muffler, spherical resonator, and a new 4-2-1 header for a combined weight that is 22 percent lighter than the stock unit. Additionally, a software upgrade, low temperature thermostat, and custom Cosworth badging finish off the package.

Stage 2 and Stage 3 kits will reportedly go on sale later this summer, with output figures listed at a staggering 380-horsepower in the top-of-the-crop package.
