The cheapest mugen style lip on eBay for a 92 teg are $65. I've seen em that cheap for civics but never for Integras.Best bet is to get a Polyurethane knock off lip off eBay. That way, you get the look you want and if ever it breaks, you only spent $30-40.
JDP made some nice lips for the 92-93Yeah, they don't really make any nice lips for 92-93 other than jdp or Mugen rep Lol.
Those rarely turn out well though.Theirs all ways the option to make your own.
Well it all depends on how skilled you are, and what tools you have too.Those rarely turn out well though.
