Trying to make an ATX Contour fast is like trying to polish a turd, no matter how shiny you get it - it'll still be a turd. The CD4E is nothing like the Auto in your lightning. It's heavy, weak, too big for it's own good and won't take much of a beating without spending SERIOUS money on it - which in the end will still be slower than a MTX AND from what I gather you want to go budget.
You're basically starting off on the toally wrong foot by trying to hot up "Nanna's Car".
If it were an MTX - it'd be a whole different story - but yes you NEED to go do some clcs on turbo sizing as you're clueless.
