somebody is doing a good job of ripping yoru friend off...
Reman block, $2000, turbos $1000 (or 1500 for a set up upgraded BNR's) Wiring harness? just on the Rx7 forum and pick up a used one for 2-300 bucks.
Probably the closest rotary shop to you guys is in DFW.. check out gothamracing.com. good friends of mine who do *nothing* but rebuild 3rd gens. They'll set you straight.
