I've been talking to a performance shop and he recommended that i remove all the air pump and buy a block off plate for the air pump and put new exhaust on my 87 rx7 but i need more info to do so what i can expect and whats the proper way to delete the air pump....please help

 

This should be asked in the Technical Section for the 2nd Gen Rx-7.

Deleting the Air pump is fairly simple. If you have a Haynes manual it should give you the directions on how to replace it. Just remove it according to the manual. Upon doing that you may want to remove the air pump silencer which is located under the passenger side headlight. It's not really in the way of anything so you can leave it there and just cut the pipe short until you feel like removing the fender liner and pulling it out. I 'm not sure if you have to pull the bumper off for that. There is also and air injection pipe leading to the main cat which can now be blocked off via block off plate. Upon deleting the Pre-cat and main cat you will want to port out the waste gate in your stock turbo so you don't reach above OEM boost levels. This can cause you to run lean, detonate and cause engine failure.
