i tried searching, hard to search becuz using "o2" says to small of a word.......

this is what i found, you can use a 87 300zx turbo o2 sensor or a s14 rear o2 sensor for the front sensor on a redtop sr.

but the problem is that some say they dont work and some say they do! does anyone have a up to date info on what o2 sensor i can use on a sr redtop that will work flawlessly?

thanks
