We have a guy in the Michigan Merkur club with a Super 7 kit car powered by a 2.3L turbo engine from a Merkur... Dyno'd at 250 hp/240 torque with a weight of 1700 lbs that thing moves :p It also sounds sweet with a straight pipe coming off the back of the turbo into a little glass pack muffler. Photos here:

I can get more info on the build time and cost if you like.
