All three stroking, boring, FI are trying to do the same thing... increase displacement either thru physically increasing the combustion chamber (stroking and boring) or thru ramming more air in (FI). A bored job means the cylinder walls are enlarged thus increasing the displacement. When this is done, this obviously means the walls are thinner and may need to be reinforced especially if you are going to use FI after.
Stroking the motor means you are increasing the travel of the piston which also means 'increasing' the volume of the combustion chamber.
FI is adding a turbo or supercharger to increase air into the engine. WIth added fuel, this simulates a much larger engine.
With my build, I did all three.
So for example, will a 2.0L Engine Design A stroked to 2.2L have vastly different torque curve than a 2.0L Engine Design A bored to 2.2L?
