Maybe you can answer this question for me. There are three ways to increase the effective displacement of an engine I am familiar with, Stroking, Boring, and FI. What are the characteristic differences between a stroked and bored engine from the same displacement to the same larger displacement? Does it significantly affect the torque profile? Different modes of failure for each?
Hopefully not too unrelated to the OP's thread.
I personally have an affliction for 944's, miatas and S2000's. I don't drive daily, I use public transport
OK... this is probably a question best answered by my engine builder and not me BUT here is my attempt to give you the info you asked for.
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.
