I think the JDM car is measured in PS instead of HP. 1 PS =.9something HP.

it's identical motor. They are using PS instead of HP rating. Also they are running 94octane

hence JDM = F20C and USDM = F20C1

I figured I'd bring this thread back from the grave instead of starting a new one.

I'm asking this because I recently purchased a JDM F20C swap.

It is true that the JDM F20C has 11.5:1 compression and the USDM F20C1 has 11.0:1 compression?

But no power differences correct?

thanks all.

That's because the JDM motor is still 2.0, up to 06.

1hp=1.1ps

JDM f20c has 11.7:1 compression in return giving it 147-150hp..... (yes it's rated in HP not PS)

do they JDM s2k's now have traction control?
