I have a Mahle piston set marked up as graphitized vw 1700 big bore. the pistons are 87.93 mm (stamped on top) and the Mahle part no appears to be 16515D manufactured 150500. Any ideas what engine they fit? or how to id them? I have the Mahle downloadable catalogue which draws a complete blank. Any info greatly appreciated

Sounds like an 88mm P/C set, 1679cc. If the cylinder base (where it slides into the case) is ultra thin, then they are slip-in 88s. If it's relatively thick, like stock, then they're machine in 88's. --Ryan
