Swiss Toni Posted January 7, 2025 Posted January 7, 2025 (edited) Anyone ID these pistons for me? Measure up at 74.8mm. Letter C stamped into crown near inlet valve cut-outs. 4084 cast into the left pin boss, and what could be a W in an oval in the right. Wiseco? Low comp Turbo?

Duckndive Posted January 7, 2025 Posted January 7, 2025 they look stock height what do they measure from crown to pin centre ? Quote
spondonturbo Posted January 7, 2025 Posted January 7, 2025 75mm is 1170cc from memory. look standard compression flat top. 18mm pin? number sounds like a wiseco number but maybe an old one? Quote
