That's a outstanding engine, in my Ranger I never got less them 28mpg and was in the 30's most of the time, your going to run into oil pan issue's that you'll have to figure out, and the ecu and wiring is going to be fun.... My buddy has a Mazda Speed 3 with the direct injected 2.3, his car is a daily driver and makes over 400whp.. with a completely stock engine, just bolt ons, the thing went 11.6's at 120 last time out.... if I could figure out the wiring, I'd try the swap,
