NEED HELP ASAP: Which starter do I need?

[trry96]

I bought a basketcase 325is and it didn't come with a starter. I bought a new engine (m20b25 from 87 325is) and went to the junk yard and got a starter off of a 90' 325i. After reading the Bentley, it says there are 2 different starters. 1 has 1.1kw, the other has 1.4. It says they aren't interchangeable. Which one do I need? How do I tell which is which?

THanks in advance for your help.

I'm thinking that info might be in the Bentley somewhere... In the event that a starter from a 1984 325e is compatible however, I have a good one, and you can have it for $30 plus shipping.
