“grunt”…. So the word implies low end torque?

“Putt putt”… not sure what that means… possibly lugging it around town… no racing?

94mm seems to be an acceptable overbore.

If I were going to do that, I’d have the block sonic tested and magnafluxed.  I’d keep the compression 9 or below.

That much overbore will increase the power.  There is a list of optional mods and parts selection that I would carefully consider.

I’d have a conversation with Jim at 22RE Performance and one of engine builders at LCE to get their input.

I don’t know if there is any kind of non-manageable cooling issues with the thinner cylinder walls?

I would weigh the cost of a big overbore for power gains vs. other optional modifications for power gain.

With a big bore will a ported head, larger valves, and a torquey cam be an important complement?

If I took a factory stock 22R and bored to 94mm and rebuilt back with no other mods, I’d get about 7 lbs of torque and a 2 HP gain.  In my experience, 7 lbs of increase torque would be noticeable.
