I just think it's cheaper DIY(ka-t).. I'll be spending about... oh 4.5k and laying down a consistent 300whp (turbo + mildly built motor) which is just fine for me.. that's after a crank balance and blue print to improve the revving ability, stronger internals, port n polish, valves n springs, and you get the idea

and the motor was designed for the car. there are more factors involved than just the weight of the motor. it 'fits'.. I know the RB has it's great mounts and all that but a KA looks so at home in a 240sx engine bay
