Hey whats up fellow Rotor heads!. I just got my Air/fuel gauge and was wondering which O2 sensor I should buy?. I want a cheap one that is gonna be pretty acurate. Also should I get a One wire sensor or a heated Three wire one?. Also could you possibly give me a part number?. Thanks.

 

im using my stock sensor. is a one wire sensor. i dont know how much cost but i think about $25 to$40.

 

Thanks for the info but my car never came with a O2. I have to weld a nut on my headers to put a sensor on it. Awhile back I thought I read about PeeJay putting a 80's GM sensor on White Trash, but I cant find a thread on it. I think im gonna get a 3 wire sensor tommorow and hook it all up and see how it works. Im just afraid that a GM sensor might not work to long on a rotary.

 

you should buy better a one wire o2 sensor because the only wire that u need is the signal one. if you buy a three wire one two of the wires are useless. a efi rx7 one 84 and up came with a one wire o2 sensor. but that my opinion.

 

I got a 1 wire one that came from my cosmo ... Sitting here in the parts pile Want it?
