Question about 24 valve M104 Head
Is it possible to update my M103 engine to an M104 by replacing the head assembly and any cam drive parts? Are the basic engine blocks and bore sizes the same? Are the pistons different? How about fuel distributor MAS and EZE?
Otherwise, what about dropping an M104 engine complete into my chassis - will it fit? what else would I need to change? Has anyone done this successfully?
(I'm not feeling very sedate today)
