Cosworth has introduced a variety of Power Packages for the Toyota GT 86, Scion FR-S and Subaru BRZ.
First up, the Stage 1 package has an optimized ECU, a stainless sports exhaust system and a "performance filtration solution." These changes enable the 2.0-liter four-cylinder engine to produce 220 bhp (164 kW) which is an increase of 23 bhp (17 kW). Customers can also order an optional front pipe, with a spherical resonator, which increases the output to 225 bhp (167 kW). The company also offers a performance manifold header that brings the total output to 230 bhp (171 kW).
Cosworth also mentioned some other packages which increase the output to 325 bhp (242 kW) and 380 bhp (283 kW) in "race track configuration" but unfortunately they declined to elaborate.
