@DannyP posted:I don't know about the newer ones, but on the older Subarus you could reverse the intake manifold and put the throttle body on the pulley end of the motor instead of the flywheel side. I think some wiring has to be modified and possibly some water hose stuff.
It looks possible from the pictures of yours I can see. Obviously flip the coil around and swap short/long plug wires.
Then you should easily get a throttle cable to it somehow. If you have drive-by-wire, you should be set, maybe making a small cut in the firewall to get an elbow on the throttle body, then mass airflow, then air filter. What ECU are you using?
This is an option I hadn’t considered, it looks possible. Mine is a cable throttle body with stock ECU. Thanks for the idea👍
