Road rage how much will the extra stroke of .2 yield as power gains under boost(turbo) compared to the 2.0l
given same turbo kit only a 2.0l and 2.2l as a diff which would you expect to have better gains, and will the redline be a factor on this?

Is Certs a candy mint or a breath mint? 
I think we are saying the same thing, at different ends of the reciprocating parts - piston speed is the traditional indice, as the piston skirt will usually fail first. I agree with you completely that the force of acceleration and deceleration will also put mechanical and thermal stress on the crank bearings and con rod.
For the technically inclined, here are some useful formulae:

For the non-technical, a good writeup.

You asked "aside from the ecu what limits such revs?", we said the connecting rods, for one. You then clarified with a mention of building up the entire engine, but if that's what you're doing, then NOTHING prevents it. You plan on replacing all of the parts that will prevent fast spinup, so FI or N/A, it doesn't matter.
