DI Head

Do the Direct injection Listeroids use a flat top piston?

does anyone know of a piston from another diesel that has a 4.5" piston with the toroidal combustion chamber in it?

I do not know anything about them, but they may be able to answer your question, then you could tell us what you found out.
Also, maybe any lister-oid could be converted to DI or the other way around? He probably sells spare parts too.
I have been working on plans for propane, natural gas, producer gas and gasoline conversions (multi fuel engine from the opposite way the US army did it). The neat thing about these is how easy they are to use as-is, or change, or just "gussy up"
