I have a 1st gen with a 12a and I am looking to autocroos it so I am getting rid of everything I dont need. I am trying to find out if the Air pump on the motor is really needed or can I do with out it?

 

You can do without it.

 

If he has an '81 and up he can do without it, provided he removes his catalytic converters. If he has a '79 or '80 he must, must, must retain the air pump unless he ditches thermal reactor and gets a header in its place. The thermal reactor, much like a catalytic converter, needs a fresh air source to operate and without it will burn out, possibly damaging the engine in the process.

It's not as easy as the blanket 'ditch it' statement from Alex-7 may suggest.

 

So I can take it off as long as I take the Cat off also? Cool that helps as I was planning on dumping the cat anyhow.

 

if you pull the cat, be prepared for some noise

 

Yeah that I know. It is mainly going to be a race car but I am going to keep it regestered which means I will have to get it tested once a year, and it will need the cat to pass the smog test

 

Keep the emmisions stock. You will not pass CO's test without the air pump and cat. You can remove the pump and install an aftermarket header and exhaust setup, if you keep the stock setup to put back on for testing.

 

So what is the air pump for? Mine was not connected to anything so I was not sure but the only connection I saw looked like it pluged in to the stock air box on the carb, but that is getting changed also.

 

Air pump pumps fresh air into the cats to help clean up the exhaust and preserve the cat. Download th 85 FSM in the stickies, the emmisions should be similiar enough to get yours hooked up correctly.

 

i have a noob question to add to this topic... where is the air pump located, im pretty sure my airpump is gone, since my engine bay has been very empty looking since i bought the car.

 

On my FB the air pump is on the left side of the block. I dont think the RX7 with EFI have them, as the guy next door does not. But I am new a dont know for sure.

 

You may want to search on "Rats Nest Removal" this will explain how to remove all the unecessary crud under the hood.
