YCP Vitara 75mm Piston Set

The YCP Vitara 75mm Pistons are engineered for D15/D16 engines in forced induction (turbocharged) applications. Constructed from a strong AC8A casting, these pistons are T-6 heat-treated for enhanced durability and resistance to high temperatures. Each set includes four pistons, 19mm floating wrist pins with clips, and a complete ring set. The Teflon coating on the pistons promotes a longer lifespan, improves cylinder sealing for reduced blow-by, and decreases friction for potential power gains. These pistons are designed to be compatible with stock D16 engines, and forums indicate their use in builds producing up to 400 HP. The Vitara pistons offer superior lubrication to the wrist pin via dual oil holes. When installing, it is recommended to orient the pistons with the arrows pointing towards the flywheel side of the engine for correct valve relief and piston pin offset. The Vitara pistons offer specific compression ratio figures when used with different D16 block and head combinations. With a D16 block and a D15B7/D16A6 head, the compression ratio is 7.3:1 with a standard 137mm connecting rod, and 8.1:1 with a longer 138.63mm connecting rod. These pistons are intended for performance applications and are a key component for building a robust turbo D15 or D16 engine.
