Do you think this position is acceptable if I were to run Port Injection?

Will the HFS-6 work with this setup? The secondary injector ports are the ones on the top.
I am concerned that the placement of the water jets will be too close to the injectors.
Essentially, the car will run a built 2.5l block with a twin-scroll GT35R with 1000cc injectors.
Also, the intention for the installation of the HFS-6 is to prevent detonation. Would you recommend a 50/50 mix with methanol? Would that provide a greater margin of safety?
Thanks!

If you are running port injection, it is advisable to put a jet at the exit of ther intercooler (FMIC) or before the TMIC. Put smaller jets (0.4mm) at the ports. 50:50 is an all round performer.
What is the wall thickness on the secondary inject port. The threaded hole for the jet should not thicker than 5mm.
