NA's are easy and straight forward. No real secrets, removing the fan and shroud will give you plenty of space to work with and can pull it up and out w/ a stock radiator or remove the sway bar to go through the bottom.
Had to replace the one on my TT twice and I have a Koyo radiator in. With the fan / shroud off and sway bar removed it drops out through the bottom. Little more tricky with the turbos intake/boost hoses, I didn't need to remove all the hoses like the FSM indicates.
