I just found an EJ20 turbo on ebay for $800.00 and I was wondering how hard it would be to do the swap? Engine, harness and ECU? Anybody ever done this or the WRX swap? Let me know, I am very interested.

The easy part is that it will bolt right in, the hard part is the wiring. It is possible to install this set up using the complete front wiring harness and ECU from a 91 to 94 Legacy Turbo. The engine will run, and for most people will probably work just fine, but if you are looking for performance, you'll probably have to add some other engine management electronics.

you would need to find a turbo crossmember from a turbo car... or else the up-pipe would not fit because of an area allowing access through there.

 

Also, an ecu swap is a wiring fiasco, some saying it takes 40 hours or more or solid work. bleh. not my thing. and you'll want of course a tranny capable of using up that much power without grenading, and a better fuel pump.

I am going to the Subaru dealer tommorow morning, I think I am going to lease a new Legacy. 250hp and I can smoke Audi TT's not to mention a boxter... I am soooo there.

depends what car it's from, if it's an ej20g you'll just have a few wires to add to the harness, if it's an ej205 or ej207 you'll have more problems with wiring.
