Can someone confirm this is the brake booster nipple off of the manifold?
I've read through the FSM. Looked under Fuel and Emissions, Brakes and Engine. The larger nipple connects directly to the Secondary chamber. It has been alluded that its for the brake booster line. Hoping for confirmation before I seal it up. The intake is going in a SA22C and that does leave some revisioning of the lines.
Yes, the larger nipple on the intake manifold is typically for the brake booster line. It connects directly to the secondary chamber to provide the necessary vacuum for brake assist. Given that the intake is being installed in a SA22C, it's crucial to confirm this through the Factory Service Manual (FSM) and any specific diagrams for your setup. If everything matches, you can proceed with sealing it up.
the US T2's have that nipple on the manifold, the JDM ones have the banjo bolt on the lower. its an odd thing to be different.
if you're doing a T2 swap, the JDM one is probably easier
