I eliminated emissions for a few reasons:
1) More vacuum lines, solenoids, and other crap to break and therefore diagnose and fix.
2) It looks like shit. There's a reason it's called the rat's nest.
3) Weight. The lines and solenoids don't weigh much, but the ACV, air pump, and air pump intake probably make up ~15lbs.
4) It further familiarized me with the car, its systems and how they were originally made to work, and then how I can improve or improvise on that.

^^^ I can see why someone would want to do that. This car, however, is going to be DD so the ACV, air pump, OMP, BAC, thermowax, 6PI and related components will be retained. If I can remove some/all emissions equipment and retain those then great, otherwise everything will be staying in.

why would you want to keep the acv, air pump and the rat's nest?

The car drives fine w/o them, you can keep the other components like the OMP, the BAC, and warm up pellet, and remove the rest like I already said. I dont understand how "being a daily driver" has anything to do with keeping that stuff, cause it BARELY affects drivability....

see? That's what I'm trying to figure out... I don't understand the need to keep almost any of it? To me, it's old useless crap that's taking up extra space in my engine bay, and making it look ghetto. Same goes for the stock fan and air box... I understand that some states you NEED to keep some of this stuff, but i can't imagine why anyone would want to unless you are trying to restore the car perfectly stock down to the last detail?

Emissions removal also makes it a lot easier and less of a hassle to pull the top intake off if you need to have access to the injectors or wiring harness.

I have S5 and I'd rather keep the 6 ports functioning so that means ACV and air pump are staying. If those are tied to the rat's nest (ie, it can't be removed without losing them) then it'll all stay. There are some decent hills and such where I live, I'd rather keep what little bottom end torque I have.

Because im only 21 and do not plan on driving a 1986 mazda rx7 base model for the rest of my life. Why would someone want to buy my car if i have to tell them that its not legal in half of america to drive (technically all but you can go without where there are no emissions test).

I was just proving that instead of going through all the work of taking apart half my engine and buying 40-50 dollars in block of plates and caps, and lose bottom end by wiring open my ports, i spent 6 bucks and an hour of my time to get low/top end torque and still keep my engine intact. I plan for the future. Now my 10th ann im going to ditch it all. I plan to run that to the ground...

Im also tired of all my friends ditching broken components of there cars, ghetto rigging the engine to run without them then using the "i took it off for weight reduction excuse" If i can have an average 150-200 pound friend ride with me and not notice to much performance loss, i dont see the need to ditch 30 pounds of crap, unless im gutting the interior too. And power steering, and ac, and heat, and my radio...... Its all or nothin man.
