subie guys need your help again. after finding out that a 911 engine rebuild cost over 8k the subie or v8 path is looking good again. if i ran the 2002-2004 wrx 2.0 turbo motor what do i do about the engine control unit or engine management. can the engine be run with the stock subaru ecu or does it have to be switched out to a standalone unit. if the stock ecu can be used, how hard is it to wire into the 914. thanks.

The stock ECU can be used. There's at least one conversion done by a person hear who did that, and a great many engines are swapped into Vanagons using the stock ECU. You can also use a standalone unit, and esp. if you're using a recent engine (post OBD-II, so '96 or newer), you won't have to fool with quite as much stuff to "fool" the ECU into thinking it's still plugged into a Subraru. There's also a member here who's done the swap with a Megasquirt ECU, so you'll find help here either way you decide to go.
