This 2.3-liter S14 inline-four and Getrag 265 five-speed manual gearbox are said to have been removed from a 1989 BMW M3 that was acquired by the seller in 2019. The engine retains a BMW M-branded valve cover, wiring harness, miscellaneous ancillary equipment, and a Bosch Motronic ECU that has been fitted with a Turner Performance chip.
