Well, that's exactly why I was suggesting it. If I were to bore it out to the FA20DIT's specs, for the lower compression (10.6:1), and run DIT's pistons and rods (or aftermarket forged DIT piston/rods), I could make some really good power... Especially since the D4S has the superior Toyota direct injection.
Of course, it all comes down the the tranny once you start achieving a high torque output; this is evident is @
Reaper's build.
