never mind the haters. they have bugs in thier bums. The good news is this. If your getting a clip you WILL be able to use the headlights. The headlights are the most expensive item involved in the conversion. It would cost you less to get custom conversion fenders to do the face swap then to have custom work done to the stock body panels from an s15. So I would abandone that idea...
So heres what you'll need from what I understand:
s15 Lights - you have these
s14 -> s15 conversion fenders - to be had for 800 iirc
s14 -> s15conversion hood - you may not need this i dunno
s14 -> s15 conversion bumper - you have this. right?
swap specific light mounting brackets - you need these with the s13 swap, the s14 I dunno...
double check all this with a proffesional/expert. I may be wrong about some/ a lot of this stuff. I would just do the sr swap and tune it. this alone will take lots of time and money. once thats done, you'll still have plenty of time to figure out how you want to do the body work. Again, I am not an expert. I wouldn't have tried to give you this information as I am not 100% sure on this. But everybody else who bothered to answer was a dick, so better me than nothing...
for the ASSCLOWN who told him to get an s15 and not make his s13 a show car. Your a jerk. To import an s15 would cost outrageous amounts of cash. Why can't someone turn an s13 into a show car, are they not appealing looking cars? ASSCLOWNS
