A ? about direct port with inject spacer.
Ok, what are we looking at? 1st pic looks like an alum block machined to similar to a NXL/NoZZle/CDN Nitrous bung, but the 2nd pic looks like it is integrated into a aluminum manifold?
If it is a block, 1st machine it so it fits on the intake, hence most others are smaller all the way around. 2nd, machine in two passages for the fuel and nitrous to flow through, then tap them to accept a jet holder fitting. Look into the three mentioned above to ensure the nitrous&fuel enters at an angle that facilitates good atomization and wont allow fuel to be pushed back up the bung.

It's a Raylar Cool Can intake for a 8.1l. I have foggier system but I don't want to drill and tap the intake especially sense its a sheet-metal intake. Future planes are to remove the nitrous and zipp-tie a pair of turbos.
