Thanks for the reply! For my needs I hope I won't need all that stuff.

Just doing some quick calculations. At 220BHP, .6 B.S.F.C, .8 Duty Cylce, 43.5 pressure at rail, I'm going to need at least 41.5psi 436cc/min injectors. What I found was BOSCH EV6 injectors. Did I do the calculations correct? 220BHP is what I would like to get.

Also Im not trying to make my car 300hp or something like that. Honestly for my first turbo build, I can't be happier If I can get 200+hp .

Alright thanks. Ill see if I can get away with my factory ECU. But if  I get MS, Ill just call someone over just to get me started. I hope I have all the parts in my list to make my turbo work. I pretty much know how to put everything together, just the software is bugging me. Anyways I won't be doing this turbo for a while because I'm still researching.

Sounds like a great idea - the Z3 is a great platform for a bit more power.  That isn't a crazy amount of boost, you might be able to get away with a rising-rate fuel pressure regulator (RRFPR) and larger injectors with the stock DME/ECU.  I'd also strongly recommend a WBO2 and some additional instrumentation.  That's how a PO upgraded my '84 745i, the car runs great.  I don't have any firsthand experience actually doing this to an M4x though, but there are a bunch of guys here that have.

You'd also have the option of a standalone ECU like Megasquirt or VEMS.  There are also a few members on this board can help out with programming - PM BMWConnect and see what he can do for you.

Thanks for the help! WBO2 is definitely on my list. Just a few more questions. How do I know what injectors to get? Do I have to do some kind of calculations? If I do consider buying a Megasquirt I would probably have to modify my wiring harness to hook it up, right? And what is the next after I have my setup installed and ECU installed? I just can't start my car.

.60 Turbo
External Wastegate less than 7.5psi
Custom exhaust manifold
Boost Controller
Small Intercooler
WBO2 sensor
Custom stainless steel exhaust
MS3 ECU (If I need it)
Larger injectors
RRFPR
Air/Fuel ratio gauge
Boost Gauge
Blow Off valve
Mushroom intake filter
Aluminum Piping
Bosch 044 fuel pump (If I need it)
Anything else?

Hello, I am most likely going to install a turbo into my Z3. I was thinking on a T3 .60. Boost will be less that 7.5psi. If I install a turbo chances are Im going to need a new ECU correct? If I do, do I have to program it? If so, how?
