It also comes with a Continuously Variable Valve Timing System (CVVT), which optimizes valve timing for both low-end torque and high-end horsepower.

Moreover, the Subaru 3.6L engine features a twin-scroll turbocharger, which provides quicker turbo response and improved power output. The engine is also equipped with a high-pressure direct fuel injection system, which ensures precise fuel delivery for better combustion efficiency and reduced emissions.

Adding to its durability and longevity, this engine features a cast-iron crankshaft, steel connecting rods, and forged pistons. It also comes with a maintenance-free timing chain and a dual mass flywheel for improved power delivery and vibration reduction.

The Subaru 10100BS840 engine is a sophisticated and powerful unit that delivers impressive performance and reliability. Its unique Boxer design, advanced technologies, and robust construction make it a standout choice for Subaru enthusiasts seeking a high-performing and efficient engine for their vehicles.
