The houseing on the SC, S, E, and T (small differences in compressor housing size) are all the same. You actually have the ability to rotote the compressor housing and move the oil return around. SHO Shop sells the S-trim with their kits. If you're going to buy blower for your SHO, I HIGHLY advise you to get a T-trim because they are much more effecient.
If you have the kit that includes the bracket, hardware, piping, etc... It's fairly easy to do. You'll have to swap out your injectors, take off your oil pan to drill and install a fitting, change your fuel pump, and whole bunch of stuff will have to be done. Lastly, you will have to have the ability to tune your car. The LPM simply will NOT do.
I advise against just buying their complete kit. If you like their kit, just buy the base kit advertised on their specials page.
