I am so not understanding this after searching and reading. What do you do with the split air system once you remove the air pump? What if you bypassed it and sent a hose straight to the cat and plugged up the inlet that the air pump hose off the back of the air pump hooks into? and if you plugged the outlet underneath the car that goes to the split air check valve? would this cause any bad effects to the engine? I have been studying the FSM and the forum and can't figure this out? What happened is since I failed emissions 4 times, I tried to rig up the air pump to blow more air into the new high flow cat I bought from the rx7store. I basicaly changed everything I could back to stock and now there is a problem. I now have a nice fume of smoke coming from the passsenger side right above the turbos. It did subside after about 10 mins. Also everything seemed to get real hot, the tranny tunnel and the UIM? I am suspecting a FPD problem. There is a nice smell of fumes, either gas or exhaust, a little hard to tell and a little concentration of black smoke coming out the tail. I drove it around the parking lot once and it was not responding well. I did not boost on it, just around the loop? Two days ago it was running perfect. I mean no issues. Boosting properly, I drove over 100 miles on it nothing? Does anyone have a clue as to what I am dealing with here, it seems like the more I try and fix the worse things are getting. I am also up in the mountains and have no one to help me. I might be loosing my mind so please any help will be appreciated. opinion, fact, hypothesis, I want it all. I have got this far, can someone help?

I dont understand any of that post.

Can you tell us what the current spec of your car is, and what you want to try to acheive?

Do you have an air pump? Do you want to remove it? if so, why? You need it for emissions. And if your going to run no air pump, you may as well remove the main cat. Do you have a PFC?

If you aren't passing with the air pump hooked to the cat, you need to stop wasting time messing with the secondary air injection system and fix what's actually wrong with the car.

Just totally remove the ACV unit and replace with a cover plate. This includes both pipes for the AP inlet and outlet to the ACV.
We have to do this when going to 1600cc secondary injectors.

The metal pipe which was bolted to the back of the ACV is kept, but cut off the flange. The other end goes to the valve and to the cat. This pipe is where the air flows through to the cat from the ACV. Now fix a hose to go from the AP outlet directly to this pipe. Now the AP pumps directly to the CAT through a less restricted system.

So easy!!!


This is how my single turbo is setup. Once a year I swap my cat for MP, load in my PASS EMISSIONS PFC DAT, and I pass the test.
