From what you are saying, it looks like a total of 5 jets I will be needing for the setup. 4 for Port Injection and 1 for the exit of the Intercooler.
Will the pump of the HFS-6 keep up with the demand of 5 jets?
From what i recall, the wall thickness is around 4mm or so, I will need to take off the manifold to make some measurements but from your diagram, the optimal position for the jets is going to 5mm so I will add a washer just take make sure that the water jet will be perfectly aligned.
Do you foresee any issues with the water jets positioned just about 1" before the fuel injectors? I have never implemented Port Injection before and especially on a setup that will be running 2 bar of boost. Any issues with water jets being unable to spray due to the boost levels?
Thanks for the help!
Cheers

The HFS-5 is scalable so using bigger jet is perfectly OK.
As long a is the water jet is installed beween 3 to 5mm, the spray will be good. If the wall thickness is larger than 4.5mm, you can always put a chamfer in the hole. (you need a chamfer anyway to bed the o-ring on the jet. I suggest get a bunch of Brass jet adaptors so the jet are seated properly.
The pump can support 5x 0.5mm jets easily.
