racing

I'm building right now a Fiat Uno mk2 sx for a rally. Engine bore and stroke is 80.5x67.4 I want to replace injection for bike carbs, put x1/9 1500 euro spec cam, 39.5 intake valves, make a new 4-1 header, skim and polish the head. The question is how light should be a flywheel to keep some torque?

I hope everyone had a great Christmas. Since I had some free time on hand, I put together a short compilation video of various racing X1/9s. Hope you like it.
