Thank you for the link, it was informative.
I'm curious why Toyota went with thinner connecting rods with the VVTi? Best guess was for less rotating mass to eek out a bit more gas mileage efficiency (shrug)?
I'm curious what the actual net effect is on reliability, though, since everything else is the same. If people have gotten 800rwhp out of the 'weaker' connecting rods, then they must not be total junk. Surely a more DD friendly 400rwhp build wouldn't be a problem by that measure, wouldn't you think?
