New 82 RX7 GSL owner looking for carburetor help.
I have purchased my first car recently, a 1982 RX7 GSL, that needs a new/rebuilt carburetor and a air filter(the whole thing, it's just a hose hanging there), as well as a catalytic converter, but I'll deal with that once the car is running.
I would like some advice or help with the carburetor, should I attempt to do it myself? and also, is it much different than a honda carb? Should I buy a new one, and if so, where should I buy it from, and what brand is good for performance.
About the air filter, where should I buy it from? and what is a good performance brand to buy for it?

There's plenty of resources on this forum for rebuilding the carb. It's not particularly difficult, just time-consuming. So far as the air cleaner assembly goes, you should find a stock one and a good-quality paper filter.

Others here know why more than I do.
When I got my 84 GSL from my father, the first thing I did was buy the Haynes Mazda Rx-& 1979 thru 1985 book. It has the tear-down and rebuild of the carb, along with tons of other information. When I had to have the clutch replaced, I took it to our local mechanic who works on our vans. I said I had a book. He said leave it on the front seat. Having a proven procedure often saves costly and/or time consuming mistakes.

Ordered the Carb rebuild kit from oreilly's, it'll be here by tuesday. 'Till then, any advice on taking apart my carb? what should I use to peel and clean the gaskets off? What can I use to clean the emissions and dirty crap off the parts? and other carb rebuilding advice.

On the internet archive or way back machine search sterlingmetalworks. An excellent rebuild tutorial is there. Read through the 1st gen archive any thread carb related.
I bought the Gunk gallon carb cleaning solvent. It has a strainer in it, but some parts are very tiny. For these I used a small Pyrex bowl to soak. I used fishing line and spray carb cleaner with a straw to clear jets and emulsion tubes. If you have kids between 18 mos and 6 years, they must be kept away from your work area.
You're on the right track. Just read, read, and read some more. You'll learn more than you can by simply asking questions here.

You will need...
-1 can Gunk engine bright
-1 gallon Simple Green
-1 tooth brush
-Air compressor (to blow through jets and passageways)
-Rebuild kit
1. Get a giant rubber made or serlite container and fill it with nearly full strength Simple Green.
2. Make a paper diagram of the carb and remove the accelerator pump, jets, emulsion tubes, and air bleeds matching them to the diagram. You can leave the throttle assembly. When removing the accelerator pump be very careful not to lose the check ball and weight under the brass screw and squirter nozzles.
3. Soak the body of the carb and jets in Gunk. Scrub it with the tooth brush and rinse with water several times until youve used the whole can.
4. submerge carb body in Simple Green container for a few hours. Scrub and rinse it again.
5. Blow out all the passage ways and jets with compressed air and ensure the carb is dry.
6. Reassemble the carb using the gasket kit. DO NOT ADJUST THE FLOATS
The main things your looking for is that air travels through all passages, accelerator pump squirts, and the float level is 1/2 way.
