I was about to s/c my s13 sr20de, but it is a tight fit in the s13 engine bay with my selected s/c, the sc14. here are some links of someone who put the sc14 in there s14. they like these chargers down under, and use them on a lot of custom jobs. it is off of a jdm toyota 2L I6 1gtegze engine.I actually just sold one on ebay that was hella clean! just don't get a dsm one, it will have high miles and will be the smaller sc12.

while researching on the net I remember coming across someone in the states with one, but there was no info on it, maybe one crappy pic.
I wish I had been able to add the sc14, but I had no room in the s13, and damned If I was going to put it on the valve cover! also I do not yet want to modify my super clean one owner female driven s14, so I had to abandon the s/c dream, which is not as far out of reach as everyone will tell you!!!!!!! you should do it, it would be great, don't listen to the haters. It would not be that difficult.
