Im a little sensative to this comment that makes V-twins come off as "bad". Yes V-twins are typically lower in power-to-displacement by design. They are designed on purpose to enhance torque. The design does this at the expense of power. Power that a similar in-line engines gains ONLY by higher RPMs. A well ballanced V-twin is right up there w/ the in-lines (LOL ducati). So if your valuing an engine swap based on only power, i concede to your comment. However i counter with the fact that torque is a commonly overlooked design nesesity, more so for daily driving than racing. Two extreem oposite examples: Honda S2000 240hp 153 ft-lbs (gutless below 6000 RPMs but blows doors off in a flat out race) vs. TDI Jetts 100Hp 177 ft-lbs (might beat a honda FIT in a race (maybe), but dont have to drop 3 gears and darn near blow up your engine to pass someone on the freeway.
