Not necessarily that much more, just few a few things and tricks that Scott @ Heads Up knows. I didn't see anything upgraded in that trans in the list.
Scott has built drag Busa bikes in upwards of 550-600 reliable hp, yes reliable. I'm not saying I'd try and have something that nasty, but I'm sure he could build me something comparable or better for less money. He is really good with the busas.
Pretty close. Turbo kits are about 4K in parts and labor when you add one to a stock N/A motor. You can only run a limited amount of boost without doing internal mods of course.
All I was saying was it wouldn't cost 10G to add a turbo and make about the same power with my motor.
