Wiseco M50 2.5 Wiseco Piston Set - (NO LONGER AVAILABLE) 92164-4061

M50 2.5 Wiseco Piston Set - (NO LONGER AVAILABLE)

These forged aluminum pistons are a second oversize for the M50tu 2.5 liter engine - 84.91mm (3.3430") bore. Because BMW only sells original size replacement pistons up to 84.50mm your options are extremely limited if you need to bore the block beyond that. These are a duplicate of a factory piston other than bore size. Set comes with six pistons, piston rings (titanium top ring), wrist pins, and clips.

Piston Specs:
Comp Height = 1.280
Bore Size = 3.3430 (as measured on piston skirt, 1.3" below oil ring)
Suggested Clearance = .0030
Weight = 330-332g (varies piston to piston)
Valve Pocket Dia. = 1.45 (i) / 1.40 (e)
Valve Pocket Angle = 19 (i) / 19 (e)
Depth from TE = -.0900 (i) / -.0370 (e)
