i've been reading that the JDM bigport 4age has a different power output... so what is the power output? is the difference that large from the north american one? or is it really neglidgeable(sp)

130 at the crank

130 at the crank...and it's map sensor or afm?

or is that just the difference: it has map sensor....and if so, is that the only thing that accounts for the hp difference?

it's map

pretty sure that's NOT the reason of the pwr diffrence tho

just wondering if the map vs afm difference is that large...

AFM has lil air restriction, so you dun see much force intake induction with AFM on....

Hello All
There are a few hp gained threw the lack of restriction on the MAP setup.
Most of the gains are due to different Fuel and ignition curves.
Remember they get alot better gas than we do at the pump(Octane wise that is).
Hope this helps
