I run a s15 turbo and everything bolted right on with the stock manni, the only thing that changed is because the wg is so big u need a custom ac line it will melt right through it. Also since i have a s13 sr into a s13 i had to the the oil fitting from a s14 turbo to make the oil return line work. The problem there was it was smashing into the steering and keep riping through the stainless steel line lol.
