I'm cleaning up underneath my manifold, mostly all those hoses. One thing I didn't understand on how the system worked in the vacuum chamber. What is the purpose of the two hoses that go from the vacuum chamber to the ballance tube via two pipes? (two metal pipes on either side of the throttle body)

Can they be looped or pluged? I'm getting rid of the whole vacuum chamber assembly.

If I understand correctly, all these pipes do is allow a path from the vac chamber to the throttle body for idle control bypass (valve feeding from intake plenum to throttle body). So in theory they could be plugged?

At least thats what Idea I get following the valves i wanted gone.

easiest is to just run a hose from one pipe to the other, replacing the lower chamber with a bit of hose. If it is for a track car and you aren't interested in any vacum being available you can remove the whole balance tube but will need to tig the holes up on the runners.

Mine idled best with no a/c, no power steering and no balance tube, just the screw behind the throttle bodies.

    • LOL, when one "money pit" is never enough Noice, and excellent work mate
    • I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed
    • I hear that would involve some nice country road drives into the hills for Mark...
    • I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.  
    • Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
