After three years of drive my turboed ej25 (originally a ej25 na) I am preparing to build a new mid engine rail using the Subaru engine and transmission. Im shooting for 300 whp and around 300 ftlbs of torque. What ej engine would you guys suggest to achieve this without changing the stock internals. Also could a Subaru automatic handle this kind of power. If so which auto tranny and what all would I need to make this work. Any suggestions would be greatly appreciated.

Subaru made some front wheel drive automatic transmission cars and that transmission would make a super mid engine car setup.......
