Not True, there are 155 RXPs also and they are identical except for the SC and IC and the decals that say 215. Just look the back of the motor just left of center and you will see a large 1 foot diameter sc with two large 3" hoses attached, one comes out of center, one comes out the side and goes to the throttle body.
If you can take a pic of the motor, we can tell you in 2 seconds exactly what it is.
