Engine Casting number

[Berkut]

I've come across a crate 0 mile M20 engine, casting number 126 4165 090 88, can anyone tell me what engine it is?

FYI most the m20 blocks are identical, except for the 323i and 325ix.
there are a few differences year to year in featurs. but they all interchange

What I was looking for is a difference between a 2.0/2.3 and the 2.5 engine, that is not specified in the topic, also I'm in some hurry.

Bore size, the 2.3 blocks also don't have the little coolant vent holes between cylinders that go to the head.

The block was closed, so I bought it, now time to find out...

Thanks for the help.

It was probably a good move.

It is a M20b20, still, it's really a 0 km engine so I'm glad.
