On the dyno, the HKS Subaru BRZ delivered the highest peak horsepower, pushing 285.63 whp and 221.05 lb-ft of peak torque. Although the power is not felt early on, it can catch you off guard once boost kicks in later on. The HKS turbocharger ran on 15.22 psi of peak boost on our dyno. The power and torque curves dip around 4,500 RPM. This happened because peak torque was reached and detonation occurred. To over compensate for it, timing was pulled causing the curves to briefly dip. The curves then smooth out and climb all the way through, making for a seriously fun system. Designed as a direct bolt-on for the Toyota 86/Scion FR-S/ Subaru BRZ, the HKS GTIII-R turbocharger is available for stock or tuned engines. The kit can be purchased with a CATless extension or an extension with a catalytic converter.
