What are you planning to do for fuel? Carbs are a pain to set up with a turbo, so you'd either need a turbo suitable for a suck through setup, or mess around with maintaining the pressure difference for a blow through setup. On top of that the internals aren't going to be as strong as a certain other 4A engine, so you'll be limited to the power you can make safely. Wiki says the standard engine is 58kw, so even if you're putting out 70% more power thats gonna be less than a stock smallport.
Is it really worth it?
