I have two motors:

M44/51 45G 03073 - Old block

M44/51 45G 01518 - New block

According to the list I found @ https://rennlist.com/forums/924-931-...ine-codes.html

Model MY Version ENGINE Displacement Year Code Eng Number KW Hp
944 Turbo 86 M44.50 2,5L G 44G 00001>00400 162 217.2

944 Turbo S 88 M44.52 2,5L J 47J 00061>10000 184 246.7

944 Turbo 90 M44.52 2,5L L 47L 00001>10000 184 246.7
944 Turbo 91 M44.52 2,5L M 47M 00001>01000 184 246.7


These are apparently both the same type of motor.

However, as you can clearly see from the images they are different

M44/51 45G 01518 - Has 3 studs which I believe to be for the auto tensioner.

M44/51 45G 03073 - Does not have these 3 studs.

What gives?

Is it possible that the previous owner updated the motor to use an auto tensioner? I see perry 951 talking about when he did it @ https://rennlist.com/forums/924-931-...rly-block.html

Mystery solved, it is an early motor the previous owner just put an autotensioner on it. I was able to find his # in the receipts I got when I bought it, and he confirmed everything.
