So I just got my hands on an EJ22 motor out of a '94 Legacy... Now sitting on the engine stand in my garage in the process of being torn down for re-sealing and new gaskets before installing in the Brat. Thanks to Justin and the crew at www.diyautotune.com the "HyperBRAT" is in development. I'm about 1/3 of the way through assembling a Megasquirt stand alone ECU for the car. Fully tunable, open source... It's been a hell of a learning experience for sure!!
