^ I keep seeing posts like this, and never a picture or a dyno. I believe you -- but it would be real nice to see how it's done and what the result is.

X2... I want to see this on video and dyno run! Do you have this?

If I find a cheaper engine, I will try this mod.

I can have an engine for 150$. If I put prius piston, I think that I need a tuning. FIC or camcon ?

Personally, I would be more interested in the Prius intake cam than Prius pistons. The effective compression ratio on the Prius changes due to VVT-i, but I've been told by experienced techs that it's around 6.5-7.5:1, depending on valve timing. The interesting thing to me would be a Prius intake cam and a supercharger- turn the Yaris engine into a Miller-cycle engine.

oh yes I like the voodoo as long as i can see it doo its voo. until then it is like the sneaking myth of the 1k hp streetable hatch back that hunt down and devours v-8s.

and the getting another engine and building a n/a to do autocross would be a sweet project, i'm trying to get my pops in on a project with me but he is hesitant to do anything.

We can get new higher comp pistons, just sold some to a customer doing an NA build.

Sourcing Prius pistons are cheaper obviously IF they work.

in the diy section:2007 Repair Manual.

And we'd love to see some build pics and a dyno run if you do it after too.
Thank you!

Would be so cool if it worked.
