I've never heard of the B18C4, I don't know why that would have more torque than the C5....
I believe the JDM B18C1 produced 180HP. I don't know why they detuned both C engines for sale here - my GS-R passes both Ontario and California emissions (the strictest two in North America) easily.
It would have been nice to have 100HP/Liter
