Because I think that for the N/A setup, if we boost the compression ratio, we can win 10 hp... maybe!?!?

Prius has a 1nz-fxe which has a completely different style head for efficiency. Though, you are correct that it has a 13:1 compression ratio. The lower end is also suppose to be the same as the 1nz-fe. Your best bet would be to do a 1nz-fxe bottom end with an adapted 1nz-fe head. There is a thread with a lot of details on the possibilities of this somewhere on clubxb.com, though it has not been done yet.

I personally wanna see this done, I just don't have the money to do it right now since I'm building an S13.

no, the prius bottom end is nothing special.

Very true. I just looked everything back up.

The extra compression appears to come from the different pistons, no? Someone on scionlife saw gains with 11:1 pistons and an emanage tune.
