Sounds fun.......I worked in the side yard moving out a parts car 911 to scrap to make room for my Fiat 600 I just bought.Well I went out and burnt the tires off of the SL on Del Puerto Canyon Road. I highly recommend it as a therapy. 610 hard turns in 55 miles and suddenly I am feeling better.
Here is one in Modesto.......you know where that is right.......;-)Where did you come up with a Fiat 600? From what I can see that is not greatly different from the original Fiat 500 except for an extra 100 cc's
Once I get #183 I am going to look for an after market turbo and go that way with it. I just don't think 101 hp in a 2200 pound car will be enough for me but we shall see.
Good luck with the new project. You are way more ambitious than I am.
