With extensive testing both in Japan and the USA, this GReddy Tuner Turbo Kit Scion FR-S / Subaru BRZ was designed to enhance the overall performance for daily drivers and weekend racers. An ideal turbo sizing maintains the vehicles balanced driver feel, by maintaining good low-end response with the factory engine components. But the most noticeable improvements can be noticed on the factory power-band’s dip in mid-range torque and at high RPM top-end power.
GReddy dyno test showed a +93.5 whp / +68.7 ft/lbs increase at 7 psi on a stock Scion FR-S / Subaru BRZ with factory injectors and fuel pump, just adding a *GReddy-tuned EcuTek ecu, and a *GReddy Evo3 70mm exhaust, – (*not Included) But even more importantly, the mid-range torque from 3150-4750 RPM’s are significantly improved over the stock torque curve.
The Tuner Turbo Kit includes: a top-mounted GReddy T518Z 10cm2 actuator turbo on an equal length 4-1 SUS header-type exhaust manifold with dual flex joints, SUS downpipe, free- flow Airinx AY-SB intake, short-routing intercooler piping, Type-40E front-mounted intercooler with cast end-tanks and all the necessary brackets, heat-shields, hoses, clamps, and gaskets.
