I agree, but even the 36 with its mere 270 hp has an oil cooler. After all for an engine to make over 100hp/liter and be reliable under heavy use, it needs some basic tools. The cooler is no over kill IMO.
But i agree that the M103 is one over kill in engineering for the power it makes.
In my engine's rebuild i ended using my same pistons and rods
Just a new rings set. And the broken ring on piston one didnt scar the wall. All clearances were still in acceptable range despite the 230k miles + of tough usage.
