fwiw, twin turbo setups have been investigated for the contour. The problem is, there is just no room for the turbo for the rear bank. That, and the fact that a properly designed single turbo setup can provide identical or better performance (I think Mr. Hightower will show me correct here) really limits the desirability of the twin on a contour. The only benefit of a twin on a contour comes from the extra "bling" or "pimp factor" and this is more than outweighed by the extreme difficulty of just getting it all to fit.
