I believe I may have occasionally seen this car in Ajax.
I remember hearing it (at idle) and thinking "that is one hell of a cam for a car that needs to pass emissions"

(there was no question in my mind that this was not just a "cat back" exhaust I was hearing).
I am guessing, based on the pic you posted of the engine completely out of the car, that the modifications didn't end with a bolt-on turbo
