Don't just pick your cam based on how big it is. Figure out what you want the car to do. Street car,track car, little of both. also what turbo your going to use. Do you want a turbo that has good bottom and mid range power. Do you want a car that is all top end and pulls like a fright train from 6k up. Or do you want a turbo that has a nice mix of both mid and top end(more street)power. Pick your turbo and engine build and then read up on cams and see what best fits your build and goals.
P.S also don't for get intake and exhaust manifolds. They play into the mix
