very low boost possible?

Good luck!

You might want to do some reading before throwing out incorrect info. The Yaris 1NZ-FE has been proven to run reliably at 12 psi on stock internals and well beyond that with aftermarket rods. The Blitz supercharger (of which there are many people on here with them, including myself) runs at 6 psi.

The most critical component of reliability with boost is fuel control.
