IHI make the best turbo's they don't make a kit though if i were you i'd piece together the best bit's.
How much money are you gunna get all together?
if you don't know find out tell them to give you a number. if they have no idea then give them the prices of the different kits. make sure the price includes an intercooler and piping even if the kit does not.
then when you have a number see what you can piece together for that amount of money.
the kits are good starting places but you always end up replacing things down the line with better parts that you wish you had gotten in the first place.

it's the documentation of a greddy install and the subsequent upgrades from there. it's a pretty good read.
