r34 lights on a b12?

can u put r34 headlights on a b12? and if so can someone give me a rough estimate on how much it might cost?

Technically yes, but it will take a lot of custom fabrication

A couple thousand dollars, plus the cost of the headlights, which are a couple thousand themselves.

those lights cost that much?

no. you can get for under $1000. but why would you want to spend that much on headlight while with that money you can swap a SR20DE into your car??

If you have a friend in Japan he can get them for under $1000 and ship them to you, but I doubt you'll find them for less than $1000 on ebay. Maybe I'm wrong, but when OEM AE86 taillights are going for $3000 on ebay, I doubt skyline headlights will be very cheap.
