Throttle-body enlargement
With a CIS injection, does it matter which order I connect the injectors to the distributor?
Also, I want wo inlarge the throttle-body inside diameter. Here in Saudi Arabia, I have to have a local machine shop do it. What is best? I was planning to increase the diameter 3mm throughout, retaining the inside tapers as original. Is this the best way?
Also, I don't know how to remove the center butterfly valve in it. It looks like the far end is incased in brass or something. The center rod doesn't come out after removing the circular flap. Do anyone know how to get them apart?

Hi Dean, The CIS system shouldn't care which injector is connected where, they all spray at the same time/rate.
Just curious, what is the reason for enlarging the throttle body? The more restrictive side of the 3.0 CIS engine is the exhaust. What other mods are you planning to do? Are you modifying the CIS sensor plate?
