HOW MUCH WOULD IT COST FOR A DECENT TURBO SET-UP ON A B16a EM1..?

[mooshie]

just a few basics-
Injectors- $500
exhaust- $800 (inc. cat)
ECU- $500
Tuning- $700
Radiator- $200
Turbo-$1200
manifold- $400
dump- $200
intercooler- $400
sundries- $400 oil/water lines, sump drilled, gaskets, new oil and coolant, etc.
Boost control- $50, electronic-$300
fuel pump- $100
Then start adding extras-
gauges- $300
blow off- $200
etc. etc.

This would be absolutely minimum prices for new, quality parts, and in all reality you wont pay minimum for most of these. ECU and tuning can really bite you, mine cost $2500 including boost control then add tuning to that as well (Autronic SM4).
get a Greddy kit and you can take the cooler, manifold, dump, turbo and lines off this list and substitute whatever that costs you. Notice that there is no labour costs apart from tuning in this list? most workshops cost about $80-$100 per hour

I would agree with dougie. If you cant do everything yourself, $10k would be the upper limit, there are so many little things that can come up and cost you money. I wouldnt even consider or start on this project without at least $6k in the bank and another car to run around in while yours in in down time.
