Some info if you considered the Prius Piston Swap:

- Take a notch from the top of each piston due to some knocking in the yaris who had my prius pistons, other than that you just open, drop them in and run it

- 13.1:1 compression! Like always your gains come from doing changes and or multiple mods. Open up exhaust, intake, bigger throttle body, port intake.Need fuel management too at this point to tune. From what I know and believe you don't require bigger injectors but a tune at a dyno would determine that. Some have shown gains with dyno numbers at 132whp so around 145hk at the crank. No turbo.

- Tune with something like the AEM FIC, Greddy eManage, APEXI Neo, etc.
