I'm basically stock, i've got a downpipe and a boost gauge. I was wondering if its ok to get the greddy pulley kit and eliminate the airpump even though i have the stock cat. what do you guys think?

 

Your main cat will die! So leave it alone

 

This is what I have read.

"The air pump is only used for smog purposes, and will not hurt your car if it is disabled or removed. Some claim a lumpy or hunting idle when it's disconnected, but may others have no problem. I have been told that removal of the air pump will result in the early demise of your catalytic converter. I highly doubt that though, as above 3000RPM the air pump is not being used.
As an interesting side note, for those of you who wish to remove the parasitic drag (not much really) of the air pump, but want to keep a "stock looking" car for visual inspections, you can remove all the internal parts of the air pump, and leave the outside connected. Of course, simply disconnecting the the electrical connector would be much simpler, and just as effective." (http://www.scuderiaciriani.com/rx7/air_pump.html)

on a side not i removed mine wihout any problems. I took off when i had a downpipe/ high flo-midpipe and for about 2 yrs i have been fine....but all cars react differently so if you try it its your butt if your cat clogs up.

 

i just want to get it out of the engine bay really. so thanks guys i guess I'll do it

 

i guess now i have to find someone in socal to sell me the greddy pulley kit and belt

 

you may want to get a high flow cat while your at it if you ever want to sell your stock cat later. I'm pretty sure it will mess your stock cat up. (Potentially even clog it... Somebody else help me out with that one)

 

It's extremely doubtful to ever pass emissions testing without it. So, don't do it unless you have a "hook up" to get the car inspected.

 

well, i can always put it back on right?

 

Of course, but you won't really be saving anything if you are just going to eventually put it back on for emissions testing (since you won't want to remove and then reinstall all the parts that go with it like the ACV, the tubing down to the cat, etc).

The only thing you'll gain is more exhaust fumes at idle.
