The G16E-GTS is a turbocharged engine model with 10.5:1 compression ratio and D-4ST direct/port injection system with multi-oil jet piston cooling, large-diameter exhaust valves and a part-machined intake port. The turbo boost is set between 1.4 and 1.81 bar (20.3 and 26.3 psi).
The BRZ GT300 is powered by an updated version of the same EJ20 turbocharged flat-four racing engine as its predecessor. [175] The GR86 GT300 is powered by a naturally-aspirated TRD 5.4 litre 2UR-GSE racing engine and features a Hewland six-speed sequential transmission. The Toyota GR86 GT300 is 50 kg (110 lb) lighter, with a shorter wheelbase ...

Direct injection and a turbocharger are used to provide output comparable to a 6-cylinder naturally aspirated engine, and the FA24 uses "regular" (87 AKI) fuel. [13] At the 2019 Chicago Auto Show, Subaru unveiled the 2020 model year Subaru Legacy sedan, available starting in fall 2019 and featuring the FA24 as the uplevel engine option. [14]
Variable-geometry turbochargers (VGTs), occasionally known as variable-nozzle turbochargers (VNTs), are a type of turbochargers, usually designed to allow the effective aspect ratio (A/R ratio) of the turbocharger to be altered as conditions change. This is done with the use of adjustable vanes located inside the turbine housing between the ...
The twin-turbocharged version with 10.5:1 compression ratio. Pumping losses have been reduced by electrification of the waste gate of the twin turbo system. The engine achieves 37% thermal efficiency. [17] A hybrid version (marketed as "i-FORCE MAX" in North America) is also available with the same engine designation as the regular variant.
Therefore, sequential turbocharger systems provide a way to decrease turbo lag without compromising power output at high RPM. [4] The system is arranged so that a small ("primary") turbocharger is active while the engine is operating at low RPM, which reduces the boost threshold (RPM at which effective boost is provided) and turbo lag.
In an internal combustion engine, a turbocharger (also known as a turbo or a turbosupercharger) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake air, forcing more air into the engine in order to produce more power for a given displacement .
