Look at your crank sensor. If it is black, it is for a 24X motor, if it is gray, it is for a 58X motor.
As a second check you can remove the sensor and look at the trigger wheel on the crank shaft:
24X trigger wheels have two rows of randomly spaced teeth.
58X trigger wheels have a single row of evenly spaced teeth.
