Okay so I have a 84 RX7 with some mods, exhaust, street port, sidedraft carb. Nothing major just basic upgrades. I want to install an Air/Fuel ratio gauge so I can keep an eye on things, I also plan on putting in an EGT. My question is what kind of oxygen sensor can I use since the car wasn't equipped with one? Where would it get power from is my other main concern. And finally what kind of air/fuel gauge has anyone used since autometer is not the best choice for a rotary from what I hear?
let em know what anyone has used or tried. Include a link if there are any threads or links.
thanx for all and any info.

 

Theres lotsa info around here on this. Do a search for A/F meter. Also search for LM-1 . You need to get some basic info on the differences so you know what to expect. Wideband= accurate, $$$. Narrowband= cheap, ballpark readings. So it depends on how serious you are about the state of tune on your car.
