Instead of acquiring parts of the next few months just make payments towards the full kit.....much easier that way. If you're really good at welding or know someone that is, then making your own is a good option. If not....well then it's easier to buy.
I take that back...I'm going to post another kit up for sale now lol
T67 Stattama Kit (minus the wastegate).....front/rear plogs, crossover, downpipe, lower TOG downpipe, T67 turbo and oil fee/drain.....$2000 picked up since you're pretty local.
