I have a question....there is a pump on the passengerside of the motor that. I am assuming its a smog pump/emissions pump. Is it safe to remove this? Also is there a block off plate I need to fabricate when I take this off?

 

What year RX-7?

 

yes its the smog pump all that its used for is recirculating exhaust gases and also cools your manifold there might be a plate you have to convert i installed a turbo 2 intake on mine so yes it is safe to remove i did and it ran fine my guess on the plates is yes you will have to make at least one

 

The air pump can be removed, but removal means you can't run a cat and you will not pass emissions. Without knowing what year RX-7 you have I can only give a general suggestion. If you remove the pump you will also need to remove and block off the ACV, and as I mentiond you need to loose the cats.

The airpump does not recirculate exhaust gasses.

 

actually you can run a cat u have to make a block off plate to adapt to the pipe that goes from the cat to the intake

 

without the airpump you'll burn through that cat even with block off plates, at least that's how it is on the FD

 

Sorry dont know anything about FD'S Havnt had any issues with MY FC though

 

It depends on the cat. Some of them will handle running without the air pump. Most generic cats will plug up in no time without the pump.

Remember, running a few thousand miles is not a test. Running 75K is.

 

Got me there point for you i am also running a high flow cat as well that might help too

 

alright, so i was looking for this and found it, i am ordering a racing beat exaust, will the air pump removal be fine with that?

 

You'll want to remove the air pump if you went with the full RB exhaust as it's now unnecessary.
