Stock O2 sensor needed if LC-1 wideband used on a NA KA?

[amyasin]

I am installed a buitl NA KA in my S13 and want to install a LC-1 Wideband I have. With that said would i need to install the stock sensor? I know that on a turbo car I was told that both would be required. But did know if it was the same in regards to the motor being Naturally aspirated.

Thanks for your help in advance

you can install both of them if you want. but i think the lc-1 should have a narrowband wire that you can hook up for your ecu so you won't need a secondary o2 sensor

You keep the stock O2 sensor.Then you use a wideband O2 sensor for the LC-1.

Whether you're N/A or Turbo, wideband O2 sensor works the same.
