BMW Hartge 323i RS 2.3L M20 Engine, Transmission, & Euro Subframe Swap Package

The seller of this 2.3L BMW M20 engine tells us that it was modified by Hartge for a 323i RS and was purchased in 2021 with a bent valve, prompting the seller to disassemble the engine and repair it. Machine work was involved, and the cylinders were honed while retaining the first bore to reuse the pistons with replacement rings.
