did my first swap in spring of 03...it was an 02 wrx motor into a 94. I've since learned its much easier to merge obd-2 harnesses into other ob2 cars
also some of the smaller systems, cruise, abs, ac, etc...are a bit easier.
Love it and drove the car everyday for about 5 years in various states. AWD, RWD, STi 6-spd...4.11, 4.44, 3.90...factory turbo, VF39, Water injection...factory ecu, utec, link ems. It died in a car wreck Nov 07...
Now I'm doing the lazy man's route and just have a hydra that I have "minimal" wiring to deal with on the current project. Found the donor chassis Feb 08 and finally got a garage to start chipping away at it in December/January 08...hopefully it'll be getting wrapped up in the month or so.
