Just looking over that, it looks like it is just a limited roadster with Startech parts added. It doesn't look like it has the actual engine conversion that Startech was doing. IMO, if it did it would have pictures of the engine, and also have a much higher price tag.

I would definitely not buy this one sight unseen just because I haven't seen the engine.

Those wheels do looks pretty good though.

EDIT: Those also don't like 19"/20" rims on the car.
