i will be happy with 100rwkw. which i don't see as unrealistic with a nice tune, extractors and raised comp (from thinner headgasket)
if i was putting in some bigger cams i would go toda so i can still retain the VVTI, and not too large something like 264 or 272 with 9mm lift, would get a mild port and polish and a valve job too.
with these mods i would be expecting about 110-115rwkw. which is plenty. a corolla is never going to be fast in a straight line but the way i see it is straight line speed is for people who can't drive.
