M52tu engine

Remember Me? BMW Models.

It was released in the E36 i, [1] to replace the M In , the "technical update" M52TU upgrades included adding variable valve timing to the exhaust camshaft. The M52 was replaced by the M54 in the year In most markets, the M52 switched from the M50 's cast iron engine block to a lightweight aluminium engine block. However, most M52 engines produced for the United States and Canadian markets except for those used by the BMW Z3 roadster retained the M50's cast iron engine block, [3] [4] while other cars used the new aluminum M52 block with iron sleeves.

But now, knowing M52TU and M54 reliability weakness, which would be a better choice? Fox- 13, posts months. I can't think of anything that would make an M52TU a better choice. The M54 is simply better and any downsides apply equally to the M52TU if not more so. Huff 3, posts months. And a CCV replacement usu casue of oil consumption oddities is easy, as are vac leaks to fix the other common cause of modest irritations in throttle response - and it's still an utterly lovely engine to drive.

Throttle response in m52tu engine i is nothing to write home about, years ago I had a Prelude VTEC and response was almost telepathic. Wikimedia Commons. God help me, I do love it!

The BMW M52 engine is a naturally-aspirated, inline-six engine that the German manufacturer introduced in This guide covers everything you need to know about the BMW M52 engine, from the available versions, to what you should look out for when buying one. The BMW M52 engine, like its predecessor, featured a dual overhead camshaft , coil-on-plug ignition , and a knock sensor. In most international markets, BMW decided to switch from using cast iron to using aluminum for the engine block. As a result, the manufacturer shed nearly 23 kg over the M50 engine. The flip side to using the lighter aluminum alloy to construct the engine block was the lower strength and stiffness compared to cast iron. To counteract this, BMW coated the cylinder walls with a Nikasil Nickel infused with silicon carbide coating instead of the traditional pressed-in steel liners. Unfortunately, the Nikasil coating turned out to be the cause of serious concern in North America. At the time, the fuel in our market had extremely high levels of sulfur. For reference, the government mandated that sulfur content in fuel was to be capped at ppm by

The inline six-cylinder 2. The M52 engine series replaced the Mseries. This engine, like M50 engines, got an aluminum cylinder block with Nikasil layer on cylinder walls. For the North American market, the M52B28 features a cast iron engine blocks instead of aluminum ones, and only BMW Z3 model got engines with an aluminum cylinder block. That decision was made due to high levels of sulfur in the US gasoline, which has a corrosive effect on Nikasil leading to fast wear. Connecting rods are mm long. Aluminum pistons have a compression height of Those numbers allowed getting in result "square engine" The M52 2.

In other projects. Wikimedia Commons. There are various theories linking this to the PCV system and 'ring flutter' and there's actually a difference between the way the two PCV systems operate; the M54 is missing a vac line onto the PCV diaphragm that the M52 has, which is believed to be part of the problem. My second much better than the first and not so bad at higher RPM, but low revs it has a mind of it's own and is my biggest bugbear with the car. Very good engines indeed! Both M52 and M52TU output the same peak torque, but the latter peaks earlier than the former vs on the M Thanks for the picture, it's clear now that mine has a M52B I ran a m52tub25 engine to k and last i checked it was still MOT'd at k.
