Idle Control Delete - Question On Ballance Tube

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.

      Need AC Compressor for R32

      Out of curiosity, what's the reason for converting? I think @R3N3 might have the Frenchy's kit in the R33? I somehow think of you as the ambassador for realistic and clean street-driven setups nowadays

      V35 Overheat + Coolant Boil & Overflow + Engine not Starting

      careful when running the car after a boil over. Ive heard you can lose enough coolant that it won't show the right temps because of too much air in the system (or something like that). Make sure the levels are good before trying again.  Maybe a mobile mechanic can come have a look with their scan tool ?

      OK, just for some extra clarity - there is more than one option at Frenchy's. 1. You can buy the whole kit - with or without the actual compressor. The whole kit includes mounts, hoses, condensor, etc. That's either ~$2200 or ~$2800. No surgery required with this option. 2. You can buy just the bracket (~$600), or the bracket with the compressor (~$1200). Either of this or the above option "without the compressor" is if you already have an Echo comp or you are able to source one locally. Whatever the case, in this option, you will need surgery done on your hoses to adapt to the new compressor. When I said "the Frenchy's kit", I meant the whole kit in option 1. It is obviously somewhat more $$ than a $1500 OEM compressor. But if I had to spend $1500 on an OEM compressor, I would certainly consider spending double that to renew and significantly update everything forward of the firewall. Another option is to rebuild your original compressor. My R34 comp is currently dead and I will be most likely doing that to it if the spare one in the shed is also leaky.

      I’m thinking that’s the route I’ll  go, thanks for the input!

      V35 Overheat + Coolant Boil & Overflow + Engine not Starting

      By carnoobb · Posted

      Hey all, my 2004 Nissan Skyline 350GT overheated the other day with coolant boiling and leaking out of the coolant reservoir when I was parking. So today, I started it up again just to see if it was a thermostat/head gasket issue. After about 20 mins of running, temps were normal again, no coolant was leaking out and the upper reservoir hose was warm but my engine suddenly cut off. I checked the oil dipstick and cap when it was running and there was no white foamy residue and the exhaust did not have white smoke. I tried starting up the car again but it would only crank, similar to when I had a camshaft sensor issue just that now there’s no check engine light on the dash. Any ideas? Unfortunately I don’t have an OBD2 that can read the Nissan's programme.
