5k would be just for the kit and install maybe tunning but i doubt it. Don't forget clutch, misc. fluids and parts, gauges etc. Your looking at 6k easy said and done.
My kit was $3880 shipped, $300 for clutch, $100 for Turbo Timer, $500 for EBC, THANK GOD I AM getting all my gauges for free. Tunning will run like $300 for the e-manage etc.
A turbo kit is more of an inverstment
Wow i didn't realize how much money i just spent in the last 2 months
