Hi everybody

I am completely new in here. I have recently bought a 1975 W114 230.6 (my first MB) which has a Toyota engine installed. I am from Bangladesh and these are rare cars here. I am looking forward to putting in original engine and the limited choices i have are M123 early version or M102 from one MB enthusiast here.

The M123 does not have the original Solex carburetor. A small Toyota carburetor is being installed with modified base on top of manifold.

The alternative is one fuel injected M102. We don't know from which car it is coming from. I am considering the M102 since this may provide better fuel economy with similar output.

These engines are very difficult to find and are quite expensive here.

Need your advice on what should be my choice and what are challenges in putting in M102.
