Man, your definately going to have to resleeve and put lower compression pistons and all that good stuff in to run a lot of boost.
Dont forget about suspension.. That wont be cheap either. You dont want a 400 horsepower car on stock suspension.. Thatd be suicide.
You need to sit down make a list of EVERYTHING you will need to complete this project and price everything out. You will be surprised on what the price is when your done.
Gauges, upgraded parts to support a high performance motor, etc.. All of these things add up really fast. You have to upgrade fuel, and spark to handle that turbo. My guess is by the time you add all the stuff you need together you will be way over that extra $3300 youll have left.
Im just warning you. Projects are fun, you just have to make sure you know what your getting into. Talk to guys on BMW forums that have done something similar. Get suggestions on what works and what doesnt. Put your list together, and the Price everything. If it within your realm and you feel you still want to do it, then you pursue it.
Good luck and have fun.
