Sorry, i wasnt thinking about the differences. Lol. I was tired when i posted. Okay, so here's what I like to do. I want to build a turbo bike for the street that I occasionally race. My goals are to go big turbo run a 250+ standing mile then downgrade just the turbo to a much smaller turbo for street use and retune somewhere around 400 hp max. It will only have a six over swingarm, and will have stock bodywork. I'm looking to build a fast street bike, not a race bike. My main concern is it's reliability afterwards. I understand that you can choose cheap, fast, or reliable, but only have two I want fast and reliable.
