i have a 94 subaru legacy that in the near feature i want a swap. it has a 2.2 non turbo right now. which subaru motor produces the most torque/horsepower? which would be cost efficient? i was thinking a 2.0 not sure which one though. also from what I've heard its really hard to build a 2.2 non turbo. which motor would you guys prefer for a swap. ps i want it fast.
