the s14~s15 turbo install on an redtop/blacktop s13 motor is pretty simple. The main parts you'll need are as follows

-s14/s15 turbo adapter plates (these are not 100% necessary just make the install so much easier and smoother)
-steel braided coolant and oil lines (if you don't want to waste time bending stock lines)
-turbo nut locking plates (should replace the old ones so the nuts don't shake loose)
-misc. nuts bolts and washers
-exhaust manifold gasket (s15 is reusable)
-.035 oil restrictor (so you don't blow your internal turbo oil gaskets, unless your turbo has one already installed in it).
-turbo gaskets
