So far my biggest design road block has been the injection system, I'm afraid that if I use anything less than 304/316L stainless or maybe inconel 625 for the injector needles they won't operate properly or will bend from the pressure of the fuel, I'm using mechanical fuel injection, just to clarify. Anyone have any ideas, the needles need to be .0625 dia and about .375" long to work properly. Thanks for the comments, I picked this because could only find 1 diesel engine on youtube and that was built as a stationary engine, it didn't look like it would work in an r/c so I figured that be perfect.
