Technically all the MWR engine are a slight overbore... but according to Matt at MWR, even the 'big bore' GT pistons don't add enough torque to feel the difference... he said maybe 100 rpm turbo spool but thats about it.

Don't know about the stroker, you can get near 2L (not quite) that way vs 1.93 w/ the overbore.

My guess is that you aren't gonna see big differences in torque from the displacement change...

Thought the 2zz couldn't be bored out. To increase cc's your going to have to increase stroke for the most part and maybe bore it out a little at the most.

the 2ZZ must be sleeved, but you cant bore it any larger, the cyllinders are too close to each other

sighhh...why didnt toyota create this engine with aftermarket performance in mind. Dont get me wrong tho, its a really good engine, but i think it couldve been better like those B and K series.
