Add forged connecting rods, lightweight pistons, completely smooth the intake manifold on a half lighter than its predecessor, the increased compression ratio and a number of less significant improvements. The changes were significant.

Improving the performance of the E36 engine BMW M50 were achieved through advanced "brains" DME3.3.1 (M50TUB25) and Siemens MS 40.1 (M50TUB20). Appeared Vanos system, increased compression ratio, upgraded pistons with rods, appeared thermoplasty air mass meter and the number of innovations that have served the common cause.
As you can see, BMW 3 engines in one body and even with the same volume may differ among themselves, so selecting the "advanced" car, you need to consider this fact and carefully check the factory markings.
