ok, there are plenty of V6s around 2.5L. my question is, which is more effiecent (both for fuel economy and power/torque generation) and why. please note, this is not a specific question about the EJ25, but about engine mechanics in general. what does lots of small cylinders provide that less larger cylinders doesn't, and vis a versa?
Hello, I just wanted to mention that it's bad to have the cylinders too big because it takes longer for the flame front to reach the sides of the cylinders and the larger surface area sucks up more of that all important heat.
