I'm about to change the vanos so I was confirming my engine model using my vin. Now, my vin says I have an M I know of the M54 and the M52 but not the M I googled around a bit but there's no record of this I could find. After using a vin checking website, it turns out I have the M52tu. The M52 but with the dual vanos. But my vin doesn't match the typical M52tu vins. Does anyone have any info on this, or has my car invented it's own engine? Also, I see a lot of e46 s around as well as s, but I've never seen another I understand this was only made for 2 years. Out of interest is a well maintained worth more due to it's rarity?

I'd say that oil use or not, the 3. Subscribe to: Post Comments Atom.

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.

Post a Comment. M52TU is basically a variation of BMW M52 engine family, meaning it is still an inline 6 DOHC 24v with aluminium block with the exception for North American models that used iron block instead thanks to their high-sulphur fuel. Theoretically, this further improves performance and efficiency over the M It adds a butterfly valve inside the intake manifold that opens and closes to create a dynamic effect of long and short manifold for better cylinder filling over wider rev and load range. In conjunction with Dual VANOS, it should theoretically aid the engine in delivering the potent performance and efficiency that improves on what the M52 is capable of. Lets take a look at the performance curve below:. It turns out it doesn't make much difference peak torque-wise. Both M52 and M52TU output the same peak torque, but the latter peaks earlier than the former vs on the M

Updated: Sep 20, The M50 intake is legendary for its air flow capabilities which let engines rev freely past the factory manifold choke points - extending the powerband all the way to redline. For this reason, race teams have been retrofitting these manifolds for years onto all M5X series of engines, but we just made it easier! The factory manifold is bulky, heavy, and makes getting to the throttle body a huge pain. The air also has to make a bunch of tight corners to actually make it to the engine as well, not the best for flow! The M50 manifold is a simple design using long and wide runners and a shared plenum with the throttle body in the middle.

M52B28 in a E36 i. As suggested by the above curve, what they do instead is increase low-end torque. I can't say its that big a deal and I wouldn't switch to an older chassis and the rust issues that go with doing just because of the increased oil consumption. I've seen on other forum and sites that the admission manifold is different, that the managing system of the injection is MS42 version of the Bosch thing, the older version has a MS JavaScript is disabled. They virtually pay me, now. Edited by bmwmike on Saturday 2nd September Very good engines indeed! Original Poster. There are some differences in the engine design, such as vacuum lines have a bit different way also in the ETK these are not really correctly displayed since they used M52TU illustrations and adjusted them a bit. So i can go get the engine from a 99 i, and it should drop right in a 99 i, without any change. Other upgrades included a new design throttle body with the ASC traction control motor built in and throttle cable override, revised coolant passages with an additional drain back passage and a new cooling system with push fit hoses and a separate expansion tank plus [5] a dual length intake manifold called "DISA" and steel cylinder liners in the aluminum block carried over from the previous M52, these replacing Nikasil in March Pretty easy system to remember. I hit that crossroad between putting money into the one I've got or buying something else.

Engine is in good running condition, fully tested and ran prior to removal from the vehicle.

It adds a butterfly valve inside the intake manifold that opens and closes to create a dynamic effect of long and short manifold for better cylinder filling over wider rev and load range. Pretty easy system to remember. I did the CCV the other week so have yet to see if this will make any difference. They virtually pay me, now. I've seen on other forum and sites that the admission manifold is different, that the managing system of the injection is MS42 version of the Bosch thing, the older version has a MS OP, I don't know the exact date of the switch, maybe Q can chime in. Also, power peaks at the same rpm but with slightly more power for the M52TU vs on the M Both M52 and M52TU output the same peak torque, but the latter peaks earlier than the former vs on the M Compared to the European-spec S50 , the S52 is less powerful.

Compressions were all good, it didn't have any oil leaks, there wasn't any smoke on start up, and it only ever let out a bit of oil smoke right up at the red line. JavaScript is disabled. That's about the detail I am able to cover in this post.
