I love stuff like that, my Brother was a Vauxhall nut and had two small cars with engine transplants. My favorite was his Corsa with a Calibra Turbo engine, unlike his Nova that he had before, he kept it stock looking. The only thing that was a little out of the ordinary was the exhaust note. But since lots of weedy car owners put straight through exhausts on it wasn't a total giveaway. That was a fun car, there wasn't much on the road at the time that could really compare, although it torque steered like a bastard.
