The M20B25 is the only belt-driven 12-valve engine of the BMW 5 Series E34 range, and this page gathers what we hold for it. Forged pistons come in WISECO, WISECO AP and WOSSNER from 84 to 85mm and 8.8:1 to 11.6:1, with a second WISECO AP set intended for a build using the longer-stroke M20B27 crankshaft, at 8.5:1 and 10:1. ZRP forged rods measure 135mm centre to centre. The head takes SUPERTECH intake and exhaust valves, SUPERTECH 7mm collets, a COMETIC MLS gasket in 85.0mm or an ATHENA O-ring at 85.5mm, and ARP head studs. Vernier cam pulleys are available in KENT CAMS and CATCAMS.
