Re: super charger swap
Check and see if the gaskets for the lower intake manifolds are the same, if they are, it'll bolt, but I think it'll take a little more than that. I have a Pontiac that has a 3.8SC and it's block is that same as the regular 3.8 but my vacuum lines are a little different and I'm pretty sure the PCM's are different. The SC block may also run at a lower compression ratio, since the boost of the SC is going to increase the cylinder pressure under load.
Prius repellant, just add gas.
