The BMW M50 is a straight-6 DOHC petrol engine which was produced from 1990 to 1996. It was released in the E34 520i and 525i, to replace the M20 engine. [1] In September 1992, the M50 was upgraded to the M50TÜ (Technische Überarbeitung, "technical revision"). This was BMW's first engine to use variable valve timing. [2]

2009年4月17日 · Hey guys, I'm new to this so can anyone tell me how you can visually tell the difference between an M50 and an M50TU engine. Thanks. there is a trick, but I don't remember for sure, but I'm almost certain that 92 was the only year with M50, 93 and beyond was M50tu.

5 天之前 · The BMW M50B25TU is a 2.5 liters (2,494 cc, 152.2 cu·in) straight-six, four-stroke cycle natural aspirated gasoline engine from BMW M50-family. The engine was manufactured on Munich Plant (Munich, Germany) from 1992 to 1996.

New lightweight, compact pistons combined with 10.0 mm longer connecting rods reduce oscillating mass and promote smooth running. The compression ratio is 10.5:1. For improved noise levels and weight reduction, the M50 TU incorporates a sheet metal (axially decoupled) vibration damper compared to the cast (radially decoupled) M50 damper.

2024年3月12日 · In this guide, we’ll take a look at the M50 inline 6 and how it stacks up to other engines that BMW produced after it. We’ll also cover general engine specs, design basics, the best performance upgrades, common problems, and everything else that you need to know about the BMW M50 engine.

2010年4月12日 · I have read that the M50 NV has a more aggressive cam, but I can't find cam specs on a stock m50 or m50tu.

2012年9月23日 · He found an M50-equipped car (but we're not sure if it is the M50TU) and an M52-equipped car. The former is $2k cheaper but obviously a few years older and 20k km (12k mi) more mileage. All others being equal, which engine would you guys pick?

Increase in displacement and compression for more torque. Improved head flow and stronger valve retainers. Surface Turbulence valves to prevent head cracking and increase fuel economy. Stronger yet lighter forge Alusil pistons and pins. Special coated Tri-Metal. Rebuilt “blueprinted” VANOS unit. Options usually purchased with this engine are:

2011年11月11日 · With the M50TU you get better rod ratio, better rod design (the M50NV is almost a carry-over from the M20.. think lighter), lighter valvetrain (7mm valves are heavy as heck), better designed valve springs, better piston design (think lighter), higher compression...

2017年12月8日 · I've got a 95 525i with an M50TU that I'm in the process of gathering turbo pieces for and it's almost a complete setup sans the Engine management, injectors, and piping/welding bits! I plan on dailying the car and that's about it, but want some extra oomph since I drive recreationally all the time.
