The 2008+ Subaru GR WRX and STI carry over the trademark Subaru turbocharged, all-wheel drive powertrain layout as their predecessors. The WRX and the fourth-generation Legacy 2.5GT also benefit from a turbocharged 2.5-liter EJ engine, closing the horsepower gap with the STI as performance contenders. The EJ series Boxer engines that propel these chassis offer streetable increases in output with bolt-on turbochargers from MHI, Garrett, BorgWarner and Precision Turbo. Are you building your EJ engine for big power? Make sure you’ve got enough exhaust flow and a big enough turbocharger! Full-Race’s turbo kits, exhaust manifolds and intercooler kits will give you the boost you need to reach your horsepower goals.
