XCROSS

Hi. I've been doing research on this for quite some time now. And I can't seem to find the answer. I even registered for Lextreme Forums but it's taking them forever to fully activate me. Plus, the forum isn't really that active. I was hoping for someone to guide me in the right direction. So I found out that the early 1UZFE pistons were cast pistons. And the 3UZFE were forged pistons but they were smaller in height. And from the 'looks' (from many pictures) of the factory 2UZFE's they seem to be forged with the same height and ring design as the early 1UZFE pistons. My power goals are 450hp at most (1UZFE pistons can handle that). And of course, the connecting rods will be upgraded due to the factory ones being so thin. What information do you guys have on how much HP the factory 2UZFE pistons are rated for at most (upgraded piston rings)? Any info would be appreciated... Thank you.

2UZ has a totally different bore and stroke, a bit larger on stroke, but much larger on bore. I very much doubt they will be capable of fitting in a 1UZ.
