yes, it'll be 4k, but THAT's MORE RELIABLE AND CHEAPER than a TURBO (given that it'll generate less heat), and it's NA, and a heck of a lot more torque and less heat than a s/c as well, so, that 4k goes a long, way, save for the 2k you'll spend on installing it. . .
and yeah, I'm with lance, they're probably borin' the hell out of the 3L. . .
AND, power wise, it should match up right with the turbo and s/c at the flywheel in terms of hp. . .
