Like any other setup. Around $2000-$2500 if you want a car that will run right. I'm sure even with the Free T25 and SMIC is gonna run you about the same price but less headache since you can use parts that are being sold on the market. Nothing custom made.

Just a matter if finding someone that has a GA16DE setup for sale. Back when I had my T25 I found the manifold, turbo, oil/water lines and injectors for $600.
