BMW M240i G42 374hp B58B30B 2021-

The 374hp BMW M240i G42 is powered by the B58B30B, a 3.0 24V turbo straight-six shared with the TOYOTA Supra.

Sealing is a choice between the ATHENA O-ring head gasket in 83.0 and 84.5mm bore, 1.00mm thick, and the COMETIC MLX in 83.0mm, 0.91mm thick. Big end and main bearings come as ACL RACE tri-metal and as KING RACING with pMaxKote coating, in standard size, with HX extra clearance and oversizes up to +0.25mm. Two sets of forged pistons from JE PISTONS, JE Ultra Series and WÖSSNER cover 82 to 83mm, one of them drawn for a 100mm stroke crankshaft. ZRP and BOOSTLINE rods and ARP studs complete the page.
