I have a MSM turbo setup sitting on the shelf ready to go on. Don't do it, go the cast ebay manifold and china charger route. I got a great deal on the MSM manifold, turbo and downpipe, but I wish I had just kept the money for sometheing more upgradable. Even if you just want a "little" boost to start with, sure it will be ok, but you have very few upgrade options without starting from scratch. You can upgrade the compresor wheel, but for that cost you would be into the cost of a proper manifold and china charger.
Honestly if you are only keeping the car for a few months, leave it alone. Just shift a little later and live on the redline. If you need more power than that you are being dumb on the street in any case. I know everyone wishes they could spend half the money for half the power, but that doesnt work. From personal stupid experience I can honestly say that spending money on proper gear the first time is a hell of a lot cheaper that paying for cheap bandaids 3 times over!
Good luck!

haha thanks for the heads up i actually completely changed direction and decided to run a td04 from a wrx and i am building a manifold for it. This should give me more options for power as well as more reliability and I will also be doing a pnp ecu
