Hmm......Always good to be learning something...
My RS 500 rep ended up with a Scorpio 24v in it, a cracking engine and great sound, but now I think I should have gone the same route as you, a Pinto turbo is much more in the spirit of it, and an interesting thing to mess around with and setup too.
At the risk of a hijack.......(none intended)
