Difference Between M50 And M52 Engine
When it comes to performance tuning and engine upgrades, BMW's M50, M52 and M54 engines are widely celebrated for their robust designs, reliability, and immense tuning potential. Whether you're new to the tuning scene or a seasoned enthusiast, understanding the key differences and upgrade paths for these engines can unlock an array of possibilities for your car's performance. In '96, the engines became the M52, and the main difference is that the smog system/engine management parts are changed to give more information to the computer.
The differences that matter only really come into play when you're building a motor, presumably for boost. Keep in mind, M50 cars are OBD1 and M52 is OBD2. There are pros and cons to both.
That being said, I always preferred the M50. Feels like it enjoys revving high just a bit more. Whereas the M52 is more torquey down low.
Both are great engines. The most obvious difference between the BMW M50 and BMW M52 engines is the discrepancy in displacement in their highest trim. While the M50 (excluding the S50) maxed out at 2.5L with the M50B25, the M52 engine's top trim (excluding the S52) is 2.8L with the M52B28.
The BMW M52 is a straight-6 DOHC petrol engine which was produced from 1994 to 2000. It was released in the E36 320i, [1] to replace the M50. The BMW S52 engine is a high performance variant of the M52 which powered the American and Canadian market E36 M3 from 1996 to 1999.
In 1998, the "technical update" (M52TU) upgrades included adding variable valve timing to the exhaust camshaft. The M52. The M50-family, including the M52, S50, and S52 engines, are widely celebrated for their durability and tuning potential.
This hearty engine is a great platform for power-adders, such as turbochargers or superchargers. M52b25, b28 are iron blocks and backward compatible to m50, but not forward since the OBD system used a rear-mounted crank sensor with a reluctor ring bolted to the crankshaft (as well as missing the additional front cooling passage). M50/s50us used a front crank trigger and pre-OBD (OBDl), and used the same cooling passage system as the m20.
M52 b25 runs the 2.0 manifold I believe and some very boring tuning. The difference in real world torque is negligible, the m50 is the nicer to drive of the two. NEW UPDATED SITE!

Includes 2.0 and 2.5 as found in E34, E36, E46, 325i, 525i and 320i. Well, like many of you on this board, I've long contemplated an engine transplant. To this end, I'd like to know as much about the prospective engines as possible.
So let's start an m/s/50/52 engine info thread. Please post links to sites which detail the differences between the engines (pistons, cranks, heads, cams, valves, blocks etc). Hopefully, through this thread, questions like the.
