the car in japan came with the better motor, when they brought it here - they ripped us off :P

another example

k20a3+peakboost turbo setup at 10lbs of boost=about 240whp...

k20z1+peakboost turbo setup at 10lbs of boost=about 320whp

the motor responds far better to boost and airflow.....

higher redline.

k20a3 - 6800rpm

k20z1 - 8600rpm

on another note

the honda fit has a fire hazard recall.

window control mech on the drivers side if it gets wet, can short and start a fire..... honda fit's suck anyway.
