Blowers are the same unit, RSX or EP.
RSX-S crank pulley ~ 4.4"
EP crank pulley ~ 4.7"
Smaller the crank pulley, the slower the belt, the smaller pulley on the SC needed to make the same power.
To make the RSX unit fit, you'll need to cut the radiator support a little. It does not need to be cut up a bunch as previously thought but some nonetheless.

Note that this install was done on a Civic Type R so that is why the smaller pulley is used.
