wideband
Searched and couldn't find what I was looking for. I am getting things ready to turbo my rx7. Mild boost with more money into suspension, tires, and brakes. Just need a little more powaaaa. Anyways, I read somewhere about a month ago that when mounting a wideband on the first gen to make sure to put it after the thermal thing? Inbetween the thermal reactor and exhaust manifold; I assume it would be too hot for the wideband. Innovatemotorsports says their sensor can withstand up to 900 degrees. I plan to run a straight pipe from turbo back once I purchase and install my turbo parts. Until then I want to install the gauge for tuning the carb.

Like I posted, I will be installing it before any turbo parts go on to make tuning of the carb easier. Will it need to go before or after the thermal reactor? Once the turbo is installed, I know it obviously goes after the turbo in the downpipe a bit down stream. No issue there. I am wondering about the stock exhaust. No point in building a set of headers if I am going to be turboing it within the next two to three months.

omg the thermal reactor is the exhaust manifold on the SA's, what year is this car??
I got a setup for x-mas (think I may keep the wife after all lol )
Not only is location mentioned but also angle, search manufacturers sites and look at their installation PDF's, I'd post what brand but concerned I may break some advertising rule/rules on the forum
keep in mind once you go boosted you'll probably have a new exhaust system made so you'll need an extra bung

Finally an answer to my question. I know I'll need a new exhaust system once I turbo the car. That's why I said I will have a straight pipe from turbo back. I was unsure if it would get too hot before the thermal reactor. I have already called and searched innovatemotorsports website. I know the angle and such. They obviously wont list on their website in big bold letters; "PUT BEFORE THERMAL REACTOR ON RX7" That's why I came to you helpful folks to find my answer. Now I have it. Now I can go and put it in Thanks guys!

As stated above.... the thermal reactor IS the exhaust manifold on SA's (79-80). You are confusing terminology. The wideband needs to be mounted AFTER the EXHAUST MANIFOLD.... and BEFORE the CATALYTIC CONVERTER (if equipped). IF you don't have a 79 or 80 then there is no thermal reactor to even mention. If you DO have a 79 or 80 then you would mount the sensor AFTER the THERMAL REACTOR and BEFORE the CATALYTIC CONVERTER (if equipped).

This is a 85 GSL. There is an exhaust manifold, then it goes to a ~2" pipe then to a thing that's the shape of a cat. but it has a pipe about 1.5" running from the engine bay to it.

stofficer same brand I have install the disc there will be a pdf with your model that is a lot more helpful.
Ok if it's a thermal reactor engine you cannot mount before it as it is the exhaust manifold and bolts directly to the keg.
As far as I am aware Thermal Reactor engines to not have a cat. convertor.
So which is it that you have? This will greatly help in an answer

If it has a Thermal reactor a wideband wouldnt work. The thermal reactor acts like a cat. Youll get very erratic readings if you install the wideband with a functional thermal reactor. IDK if you can make it not work or not but you might be better off gettin a header and get ride of the emissions.

Alright I am doing it tomorrow. I am mounting it before the cat. 81WIDEMARIAH cleared it up. Thanks man. The thing that made me believe that it was a thermal reactor was the pipe from the air pump which is deleted anyways.
