umm - do you have any idea of how a diesel works - when you turbocharge a diesel the smoke disappears completely - your exhaust will literally clean up. Adding fuel to the equation will cause a torque increase, adding too much fuel will cause heavy smoke - but will melt down your engine in short time (read hours)
And adding a lighter flywheel is not a good idea - you need low speed torque in a diesel - a lighter wheel is used for an engine to rev high - your average diesel with its stupid high compression and literally no valve pockets cannot rev beyond 5000 rpm
