Rb26 Adjusting/balancing Throttle Linkages

[SiR_RB]

Guys it's been confirmed that I need to set and balance my throttle body linkages, they were sealed with tomei throttle coat and one doesn't seem to closing all the way

I'm confident it doing this myself, can anyone that's done this give me some pointers, should I take the fuel rail and injectors out for more room? Etc

Thanks

never done it on a car before, but is it the same as for a bike?

i.e. 1x vacuum gauge per throttle and just sync up the vacuum.

Aren't they in twin setup? I guess you would need 3 gauges at least... I have a set here if you were local. Shouldn't take too long to do once the gauges are plugged in.

Refresh after 4 years ?

Can someone confirm, this is place to connect vacuum gauge's?

They are the coolant bleed ports, you’ve welded up all your vacuum ports. The balance tube that bolts on top is a necessary part unless you’re going a single throttle manifold.

Ahh  its photo from google  

Can u show the place to connect vacuum to gauge?

I don’t think you can easily isolate vacuum for each throttle, I don’t think you even need to use a vac gauge on the rb26. Just undo linkages, then back off the butterfly stop adjusters so the butterflies bottom out. Do up the adjusters again so they just touch the butterfly stops. After that reconnect the linkages and check any linkage isn’t pulling any of the butterflies off the stops. If there is one just lengthen the turnbuckle so it can hit the stop. Once that’s done you can crack the throttle by hand and check the three linkages are synchronized, if one cracks slightly earlier than the others then lengthen that linkage slightly and try again.
