I own a weak typical scion xb. I have the looks but i want the speed that goes with it. I have been looking around scion life now since i bought the car last year. I havent seen anything written about the possibility of a hybrided motor. I was curious if anyone here knows if you can use the top end 1nzfe with the bottom end 4age. Is it possible to bore the top end of the zfe to make a 1nz-age. I think this would make a great motor, vvti with a iron block the boosting potential would be amazing. Any how i am just enquiring about this before i sell my box. I love the Box, "no pun intended" but i had a GT4 prior to this and im so bored of being passed by mopeds when accellerating, no 33mpg is worth that. If i wanted that i would have bought a civic.
