The QR25DE is Nissan's modern naturally aspirated 2.5L 16-valve four. This page is deliberately a single-product page: it currently carries one active reference, and we would rather say so plainly.
That reference is the WISECO forged piston set, offered in 89mm and 89.5mm bore, all at 10.5:1 compression ratio, in Wiseco and Wiseco AP execution. Bore is chosen at variant level, to match the oversize your machine shop has settled on.
No other part family is available for this block today.
