I'm aiming for about 500whp in my '03, I'm thinking of just making it easy on myself and bolting on a KB+Suppoting mods along with some cooling mods. It looks like it wouldn't be that much more expensive than getting 500 wheel on the eaton. My question is, how easy is the KB to install? Is it something a person with a reasonable amount of mechanical skill could do, or is it a task best left to shops? If the later, what have some of you payed for the install? I don't want to spend more than 6 grand or so total, which is why I ask.
