The M160 is a torque motor, the M120 is a speed motor.
Of course it depends heavily on your setup I find. My G&P M140 makes my gun shoot faster than my G&P M120, just because the extra torque makes the gears easier to turn.
There's other options to explore though:
-MOSFET switch (it's like $30 and increases your ROF by an audibly noticeable amount)
-More amperage (better or bigger cells)
-More voltage (more cells, bigger battery)
-LiPo (most efficient size for amperage/voltage, makes the most sense for a P90 with limited space)
-New gears (high speed or standard gears)
-lighter spring (lighter spring, less resistance, more speed)

Just for reference, I get 1100rpm with a G&P M140, 380fps spring, double torque gears, triggermaster MKIII and a 7.4v 1600mah 25C LiPo
