What Type Of Engine Does It Have?

2000 Z3 2.3 LM92549 (last 7 of chassis) produced in Spartunbaurg.

I can't find in the owners manual what type of Engine I have. From correlating different information I thought it had the M52 but I can't tell with a certainty. The door labels don't have this info. I have read that this car is actually a 2.5 but BMW wanted to differentiate it from the 2.8 so they named it 2.3 yada yada. The closest matches on Cararac are 2.0 but with M54226S1 & 2.8 with M52B28TU. Other places list 2.5 -with M52 and 2.8. So is there a way to look on the car for confirmation?

Go to bimmer.work and enter the last seven digits of your VIN #. That will give you the production info.

You have a M52TUB25 engine. 2.5 L, twin VANOS. Its the same engine as fitted to the BMW 323 around 2000.

While it is a 2.5 L engine it produces power similar to the a 2.3 L engine.

There is not much difference between a M52TUB25 and the later M54B25 engine used in the BMW 325. The later having about a 21 HP increase in power. The differences are the M54 has larger valves, a better designed inlet manifold and a different DME/tune.

Hey guys I thought I was settled on this or may be the engine type is, but I see this ///M sign (pic 1) on the steering wheel and a Roadster (pic 2) emblazoned on the door frame sill. What is the significance of this, is this car a convertible 2.3 Roady or an ///M Roady? Why do they put the ///M sign on the steering wheel?

I have owners manual but it's general and covers all Z3's. Unless it's listed somewhere I haven't seen yet?

Factory simply eliminating "excess" M branded parts. I never seen a really good explanation, I do see the "occasional" Z3 on craigslist listed as an "M" based on the steering wheel,shifter,etc
