Rav4 or Corolla 2.0L throttle body on prius

That would be from the two A or 2AL engine something along those lines I would think that those throttle bodies would be pretty much almost identical The difference in 1.8 and 2 l as far as air flow goes is not going to be a huge increase I doubt your throttle butterfly or plate or whatever barely increases in size if it does it all. Not sure why all the different part numbers but different firmwares maybe whether that would invoke any more aggressive actions of the car systems probably not that's not Toyota's generally trying to do that's what tuners do. Toyota is shooting for the best gas mileage best overall ride things like that for the masses not cutting edge for a few people that want to put their apples in that cart Toyota's looking at selling hundreds and hundreds of thousands of cars not worried about a few guys that want to tweak things to the nth degree so I doubt you'll find anything really going on with throttle body changing and I don't know what you could do to make your Prius v any faster the two z z engine in the Corolla is reasonably decent and quick they've stuffed that engine on purpose for using the Prius and choked it up with EGR and all of this and that just to ring another mile or two out of it but when you do that failure seem to go up and seem to chase you around lot of problems have been reported with this 1.8 with the FXE designation for hybrid duty so it doesn't seem like you want to be doing performance work on this smaller series of hybrid stuff maybe on the 2.5 up or something but then you have reasonable power there so you probably don't need to do a whole lot. The idea of the Prius I don't think is for speed or mods.
