There's s15 cuts on ebay, if cash is no option, go buy one.

if you're looking for actual s15 front end made to fit on an s14......

let me save you time and money, your car is gonna look like a junkyard shit box piece of shit. The conversion kits for 240sx's fit like shit. Go search nico and you'll see threads of people who did s15 conversions with a kit, then ended up throwing it in the dumpster and starting over.

to do it right, you need to buy a s15 front cut and weld the fenders together.

Stock looks better than an s14.5 IMO
