To answer your question, no you can't. The bore spacing is insufficient. You can't bore it out to use larger pistons without cracking the cylinder walls. In fact, trying to turn a SkyActiv motor into something it isn't now is not going to happen for a variety of reasons.I need to know the bore and stroke of the 2.0,2.3 and 2.5 liter Mazda 3 engines. Can you bore and stroke out a 2.0 liter to a 2.5 liter using the piston, rods and crank from a 2.5 liter.
Thank you for your time.
