The N20B20 in the BMW 420i F32, F33 and F36 is the direct-injection 2.0 16V turbocharged four-cylinder that preceded the modular B48 family, also fitted to the 1 Series, 3 Series, 5 Series, X1 and Z4.

Two active references cover the bottom end of this block: a set of four ZRP 4340 forged connecting rods supplied with ARP2000 hardware, rated for both N20B20 and N26B20, and a set of tri-metal big end bearings available from ACL RACE untreated and from KING RACING with the pMaxKote coating.

Bearings are ordered in standard, in standard with extra HX clearance, and in +0.25mm and +0.50mm undersize, which covers a crank pin that has already been reground.
