The JB4 can run anywhere from factory boost up to 36psi, the maximum possible with the boost sensor, so the peak power output with the JB4 entirely depends on the settings used. The issue with the N20 motor is given the weaker rods how far do you want to push boost? 21psi? 23psi? 26psi? If a rod goes it's an expensive repair.
