Which is the best engine model for the BMW E36 3 series?
There are many Engine models for BMW series. Like 316, 320,325 or 328. It depends totally on your choice what you would prefer. Each model has some of its pros and cons.
But about repairing your BMW car, repairing your car from an experienced mechanic matters a lot. I got my car repaired form European Auto Tech.

The 2.8l inline-6 engine (codenamed M52B28) in the 328i received rave reviews as well as awards during its time because it was one of the most technologically advanced engines at that time. It produces just under 200hp. So if you’re asking which is the BEST engine, the 2.8l is the BEST. But, if you’re asking which one is a GOOD BALANCE between fuel economy and power, then the 323 would be my choice. The E36 323i uses the M52B25 (2.5litre capacity) engine, which is NEWER than the M50B25 used in the 325i, and even though produces a lower 170hp, it produces the SAME torque much earlier; at 3500rpm (instead of 4200rpm); making it a more responsive and “drivable” car than the 325i. The 316i is really too underpowered to be practical. Strike this model out of your list right away. The 318i barely scrapes by. The 318is (16valve engine) is slightly better if you need to choose a 4-cylinder engine model. If available, with the price of petrol the way it is now, I would seriously consider the 32
