BMW Hartge 323i RS 2.3L M20 Engine, Transmission, and Euro Subframe Swap Package: Hartge-Modified Six with Repaired Head

This BMW Hartge 323i RS 2.3L M20 Engine, Transmission, and Euro Subframe Swap Package centers on an M20 inline-six modified by Hartge for a 323i RS. The seller purchased it in 2021 with a bent valve and then disassembled and repaired the engine.

Machine work was carried out, and the cylinders were honed at the first bore so the original pistons could be reused with replacement rings. With the transmission and Euro subframe included, it is a complete swap package for E30 and E21 projects.
