Was just a change like every car manufacturer does. And agreed half the stuff u mentioined isn't needed for just 300 ponies. U will need a bap definately. But the head work notneeded unless your head is bad and u want to kill two birds with one stone. I just realized I've been blowin out some smoke under boost so I think I'm needing a new head because it'd be cheaper than paying a shop to install new valves. But ur right on trqck and as far as turbo goes I've told ya a hundred times my opinion for the spa manifold. Do u have the pcv delete?
