We had a s15 front conversion done to my gf's car and you can see some of the poctures here.

Parts needed is like what the previous poster said:
S15 hood
S15 bumper
S15 headlight and headlight bracket (usually included when you buy the headlights new)
S13.5 Conversion fenders (we used Origin with pretty good results)
S15 core support is the best way to do it (we used half s15 core support, top portion, and half s13 core support, bottom portion. We didnt even have to remove the tension rods. Just cut and weld.
S14 hood hinges.
S14 hood prop.
I also bought a s13.5 headlight wiring harness from chargespeed for $150 but there is also a guy on here that does these conversion harnesses too for $130 or so.
Hope that helps.
