There have been supercharged exiges for ages
In the Europe, TTE released a supercharged T-sport, there is a place in england that has kits available, ecu and all, it is also a non-intercooled supercharger

Would of been a good buy when our currency was higher.
Rotex superchargers have been proven to work on 2zz's, usually controlled by a Power FC, might wanna lower the compression ratio when using these though.
But I don't see why 4-5 psi wouldn't work on stock internals with proper tuning.
Thing is, the rotex cars I have seen have been celicas, they have abit more space between the engine and the radiator than the corollas, so it'll be a tight fit.
Edit: rotrex (J_factor from Ozcelica)
