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.

Well, there are a number of electrical engineers on this board, and once a few more people have gone through the wiring, there will be even more to help with that. I've already helped another member here figure out some wiring stuff with their Subaru swap and wouldn't mind helping out others.

Making up plans or directions is a bit tricky because of all the variations in engines, ECUs, etc. They are all different, but in the end there is a lot that is common.

Once I actually get my car running and all the troubleshooting done I will do my best to publish the schamatics I have made, etc. But that will only work for a 2001 EJ25. 95% will be identical in concept to other Subaru engines, but pinouts on the ECU, colors of wires, things like that will be different. All of those things are easy to figure out by reading through a manual.

On the other hand you can go buy a Link ECU and they even sell harnesses. That requires far less work.
