Well, in my efforts to get going on a conversion to a Subie, I apparently
did not get the right year donar car!   Companies making conversion kits
apparently don't like my 2005 EJ25. They want either earlier -2004 or
earlier, or they want an EJ25 engine from a 2007 or later IMPREZA,  Because
the later can be tuned  to produce right at 200 Hp. I found a 2004
manifold, but what else would I need to complete the setup.

Ignorance wants to know.
