Don't buy parts because your going to have to send the motor out to be built. It's not likely a shop is going to be happy about you handing them a pile of parts and asking them to build you a motor. Also if you supply the parts when something brakes you have no one to complain to when it breaks.
Your best bet is to just buy a built motor from someone like GTM. They build all my motors. You can buy a fully built long block for $5800 with core exchange. There is no waiting. You pay for it and they send it to you. To build a motor usually takes 4-8 weeks.

Labor to swap a motor is going to be $3000. So now your up to $8800. I'm sure your goign to want a turbo kit or what would be the point. Add another $5500 for a Greddy TT. That's $14,300 right there.
Add cams/springs/retainers... + $1800.
Add a UTEC ECU + $900 w/map sensor
Add a tune + $600
Add a clutch + $1000
Exhaust system..... $1100
Greddy wastegate relocation pipes.... $750
Koyo Radiator... $400
Boost control solenoid.... $100
TOTAL: $20,950 (without tax)
So don't be so fast to buy some parts. BUT I like your enthusiasm.....
