I have everything but the crossover pipe and turbo.  I am sure you can get those fairly easily.  I have a complete motor and wiring harness along with computer.

ok perfect. i hear that the factory crossover usually has issues in the flex joints.. and where would i source a turbo? thanks for your reply.

I'm sure you can get them almost anywhere.  There are lots of T25's on ebay brand new for less than or around $200

sorry for the late reply. where could i source a crossover pipe with new flex joints?

um. . . here?  They available on this forum.
