What exactly do i need to build a turbo kit for my 328i?

[328junkie]

So im starting to build a turbo kit ive just got the compression done and passed well, im going to be using the car for mostly track and still street driving nothing huge and im looking for around 300-350hp range, im not in a rush but i want to know exactly what i need ive got a custom intake manifold done but i wanna know what size turbo i should use, injectors, ecu tuning, piping, intercooler, anything other parts i need to know becuase ill have to order them online so any help would be a great help.
Thanks Matt

garrett gt35 or similar (could go smaller but what if you get power hungry?)
biggest injectors your ecu can handle (harder to tune but better in the long run... handle more power, not quite sure on what the ol' e36 ecu is up for)
someone good at tuning
oil lines
piping
intercooler (basically the biggest that will fit behind your bumper, for that power range the cheaper ones will do, just make sure they are fairly high flow in construction. obviously better brand = better cooling)
exhaust manifold (i think the best ones over there are 666fab?? we have 6boost here :P)
decent waste gate if turbo isnt internally gated
BOV (plumb back unless you are gay or planning on going over 600hp)
The bottom end of your engine will handle that horsepower ok but if you want to break the 350hp i'd recommend forged pistons and rods (wouldn't go without them over 450hp)
If you get forged pistons and rods you may aswell get your crank out nitrided and heat treated ect. not necessary but may aswell to keep 100% reliability
Oil cooler

Probably missed a few things but just keep in mind that you will get much better response out of a good bb jap turbo than you would out of a cheap cb chinese turbo and the same with intercoolers, the better ones have less pressure drop and cool better. Depending on where you mount the turbo and how you run the oil lines a remote oil pump might be needed. always good to have one anyway.

oh and the biggest exhaust possible, get all that restriction out the way!

If you dont have a good tuner then dont bother either because the tune will make or break the car with much lower rpm spool up and better efficiency and peace of mind. Invest the most time and (maybe) money in the tune, the returns are definately worth it!

I dont know what else I need if i buy this...Can I just get the dinan software update and be fine??? I was going to prob just run it at 7psi so i dont have to mess with my engine. I am just trying to get some gain for not alot of $$$$ - thanks
