These YCP Vitara pistons are a stronger casting than the factory D-series pistons, built for turbo and forced-induction use, and they've got the track record to back it: we hold the world horsepower record on these pistons in a stock-sleeved D16Z6, and we've run countless street engines past 470 whp on a pump-gas setup with them. For a D-series boost build that doesn't cost forged money, these are the piston.\u003c\/p\u003e\n\n\u003ch4\u003ePick Your Bore Size\u003c\/h4\u003e\n\n\u003cp\u003eThese come in three sizes to match your block, so measure before you order.

They use \u003cstrong\u003e19mm floating wrist pins\u003c\/strong\u003e that fit aftermarket D16 forged connecting rods, so they pair with a proper rod for a complete bottom end.\u003c\/p\u003e\n\n\u003cp\u003eThe details add up: \u003cstrong\u003edual oil holes\u003c\/strong\u003e provide better wrist pin lubrication, and a \u003cstrong\u003eTeflon coating\u003c\/strong\u003e increases piston life, improves cylinder sealing for less blow-by, and reduces friction to free up a little power. For a cast piston, these are seriously capable, which is why they've earned their reputation on high-power D-series builds.\u003c\/p\u003e\n\n\u003ch4\u003ePair Them With H-Beam Rods\u003c\/h4\u003e\n\n\u003cp\u003eWorth planning for, because the rod choice matters with Vitara pistons.\u003c\/p\u003e\n\n\u003cp\u003eVitara pistons are designed to run on aftermarket forged rods, and the 19mm floating pins fit forged D-series H-beam rods. The ideal pairing is a set of longer H-beam rods built specifically for Vitara pistons, they put the Vitara piston at the correct deck height, which recovers compression and sharpens response without notching the block or girdle.
