The guys at
Welcome Duners are very helpful and knowledgable re Subie transplants and racing applications. Give them a shout, they're in the Annaheim area, I think (714) 994-5222
Also you might look into Megasquirt products for EM. I just read a piece on their products in Grassroots Motorsports, and it looks like an affordable solution. BTW, I am a low budget Porsche racer too, NASA 944spec class. Love to see your project, please post up some pics.
