Okay so I bought this GTU a few weeks back and I noticed the air pump was missing.

So I contacted the guy who said he took off a bunch of emissions stuff to make it faster..... well as I've learned the air pump opens my 5th and 6th ports... so he tells me he removed the sleeves of them so they are always open...
So my real question is should I hunt down the parts to put all that back or is it fine the way it is?

I'm going for the most I can get from the car I live in southern Indiana and everyone around here thinks Mustangs are the greatest thing ever and the Honda kids think they slap a body kit on their cars they have 500hp+ so basically I'm wanting fly the Mazda flag and get the most from my car what should I do... oh yeah it"s N/A.

 

I edited your post to put a capital M on Mazda..
I sent you a capital "I" in the mail,so you can Slap that on the guy that Screwed with that engine!.
Yes,you need the air pump for the ports on an s5 and removing the sleeves was unnecessary.

 

Yeah he is an idiot he paid a guy to put a straight pipe on and its iust flex pipe from the headers to a fence post to the Y pipe its pretty bad.

 

 

Yes, you want to reinstall an air pump, as well as reinstall the sleeves. While you are at it, you may want to get some Pineapple Racing sleeve inserts.

I would also try to see what "emissions" items he removed, as it is most likely not emissions but rather components that make the engine run better under various conditions.

LOL, I have seen worse exhaust systems. Racing Beat makes some good bolt-on exhaust components, and you can also order them through Mazdatrix. If you want to really maximize the exhaust, then you will need to go with a custom installation. If you go custom, keep in mind that the rotary engine exhaust is extremely loud and hot, so thick piping and header flanges are best. Heat-resistant metal like 321 stainless or a titanium alloy is best, but mild steel or 304 stainless works just as long as it is not overly thin. The Racing Beat Tech Tips will help with designing an exhaust system.

Is that just the inserts or the sleeves also cause it kinda just seems like the inserts

 

Also my problem is I dont have any of the items he took off so I have to replace all of it..... and as exhaust goes im having a shop make me a custom pipe to go from headers to my Y pipe as to keep the cat delete. As it is right now its basically open at the end of the headers cause the flex pipe is melted...

 

It is just the inserts.

Depending on how much money you want to sink into the car, you may want to just replace the whole exhaust system with better components.

 

Im haveing a custom exhaust made monday we have a shop thay mandral bends pipe well not really whole exhaust just from headers to Y pipe so I have a no cat. Ive found a air pump someone is gona sell me to be honest I dont know what all is missing first rotery. My friend was the one who pointed it out...

 

the previous owner in my S4 removed my air pump too and left all the vacuums open -_-. Should i hunt down an air pump too?

 

The reason why I recommended a whole exhaust system was because it sounded like you wanted top performance. In order to get that, you will need an aftermarket header and appropriate exhaust tubing. The original car comes with a collector, not a header, so if you are just attaching the collector to the stock Y-pipe then you are not going to get much more than the stock power level. Given your stated goal, I would consider this a waste of time and money. Now, if you just want to get the car running, then your plan is fine, but you will need to have the custom pipe modified or completely replaced if you decide to increase the engine output.

The S4 operates the aux ports with exhaust backpressure, not the air pump. However, the air pump also serves the functions of reducing emissions (also lengthening the life of the cat) and keeping the engine from "backfiring" when the throttle is suddenly let off, so if either of these things is of concern then you may want to hunt down another air pump. Otherwise, don't worry about it. However, with no air pump pulley, the water pump belt will slip unless you install a dual pulley or a yahoo belt. Be sure not to use an underdrive pulley unless you are racing at high rpm, as it will not circulate enough water at the engine rpms used when street driving.

The vacuum hoses could be a problem. The sub-zero starting system is worthless, but you probably want to reconnect the other hoses. You may want to look through the factory service manual to see what the previous owner disconnected.

Ok thanks, i have a dual belt setup already so at least this guy kind of knew what he was doing.

 

a fence post exaust!! that's a good one lol. you can also zip tie the 5th and 6th port actuators open which is what I did with my raceported 87 s4 I had you loose a little low end torque I believe

 

Yeah I went out and had a custom pipe bent and put it on their right... it was the dumbest thi I've seen in a while and the flex pipe feom the collector was melted so it was basicly no exhaust after the collector so it was loud. Ive already bought a air pump I just need to buy some sleeves now.

 

Yeah my car kinda jumps when I run it between 7k and 8k is that cause the air pump and sleeves are missing?
