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?

My second much better than the first and not so bad at higher RPM, but low ak 104 it has a mind of it's own and is my biggest bugbear with the car. An M52 with an M50 inlet would be the best of both worlds, m52tu engine, but it seems that's a tricky mod to do these days due to m52tu engine availability of donor inlets.

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.

It was released in the E53 X5 [1] and is the replacement for the M52 engine. From to , the M54 was included on the Ward's 10 Best Engines list. Compared with the final versions of its M52 predecessor called the 'M52TU' , the M54 has a non-return fuel system, a fully electronic throttle without mechanical backup , [1] [2] Siemens MS 43 engine management , [3] and a revised intake manifold. As per the M52TU, the M54 uses an aluminium block and aluminium cylinder head with cast iron cylinder liners. Variable valve timing is fitted to both camshafts [5] called " double-VANOS " , a dual length intake manifold called "DISA" is used and the thermostat is electronically controlled.

The engine was manufactured on Munich Plant Munich, Germany from to The M52B20 TU engine features a cast-aluminum alloy cylinder block with cast-iron cylinder liners. The aluminum cylinder head uses chain-driven double overhead camshafts DOHC and four valves per cylinder 24 valves in total. It is equipped with a Siemens MS Cylinder bore and piston stroke are

The M52 but with the dual vanos. Put the later engines of n52 and n53 especially to shame I currently run a n53 f10 for reliability and over a long term even fuel consumption if you factor in the repair costs. Seems Brits either search for small economical engines or the full enchilada Both looked after, no leaks and no smoke. BMW iX Forums. Wikimedia Commons. And just as a reference, BMW used to classify using 1 litre of oil every miles as being acceptable I'm not sure if this is still the case on their more modern engines. In other projects. The M54 was basically an M52TU with a fully electronic throttle body so it was compliant with optional DSC as well as a catalytic converter on both exhaust manifolds. Lets take a look at the performance curve below:.

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.

I hit that crossroad between putting money into the one I've got or buying something else. It had cam sensors and a radiator iirc. Sorry, I should have been clearer, M52s devoid of damage from Nikasil wear, shouldn't use oil. Subscribe to: Post Comments Atom. I've had two M52 s and neither used oil excessively. Other upgrades over the M52 include lighter camshafts with increased lift and duration , valve springs and the exhaust system. I depended on the build date? They changed to the oil control rings from a double pack with a centre spring, to a single ring and spring on the M All that said, as everyone has mentioned you more than likely have an m52tu due to the date of manufacture.

After using a vin checking website, it turns out I have the M52tu. I ran a m52tub25 engine to k and last i checked it was still MOT'd at k. All times are GMT I have one in my '99 i.
