Ka24de Emissions.....vacuum lines on back of Intake Manifold

[drksol22]

Ok, First there is a web of lines on the back of the manifold. i was wondering if i could take those line out because they are all cracked. the only thing i see on the forums for emission removal is for the egr and the the four pipes under the manifold. I have some red arrows on the pics and wondering if i can remove these things that i pointed to.

Picture One: Has one arrow by the vacuum lines.


Picture Two: Has two lines. EGR and some regulator on the top right.

if you dont need it to pass smog or whatever then yea you can get rid of all that junk just remember to block off the stuff that would cause a vacuum leak in the manifold

and the second picture is your swirl valve i believe people take it out but im not exactly sure how too...if you wanna leave it in there with no vaccum line to it i dont know if it would be stuck open or closed

Only line i had on my KA was the side of the intake manifold to FPR. that was it. car ran fine.
