Modifications on the car.
1. 73mm KS-Tech air-intake
2. APS Front Mount Intercooler
3. Reversed Intake Manifold
4. Custom 2.5" aluminum intercooler pipes
5. APS Tumbler Valve Deletes - secondary injector ports modified for port injection
6. Stock 560cc injectors
7. Uprated Fuel Rails / Regulator with AN-6 fuel lines.
HFS-6 installation details
1. 1 gallon Jaz tank
2. AN-3 lines from Aquatec pump to FCM
3. AN-3 lines from FCM to 6 port manifold (1 port blanked, 5 ports with 4mm compression fitting)
4. 4 x 0.4mm nozzles into each cylinder using nylon lines
5. 1 x 0.4mm nozzle 8" before throttle body, 2" behind Bypass valve using nylon line
The 0.4mm nozzles were recommended by Richard from our previous conversations for my final engine build which would put out about 400whp. But since I am installing the system before the final engine build, which restrictor should I be using on the FCM if I am intending to run either water or 50/50 methanol/water mix?
The car is currently untuned, and I want to be able to setup the HFS-6 so that I can get it tuned all at once.
I'll put up pictures of the completed install once the tune is completed.
Thanks all for your help!
Cheers

This is some late install, more than a year old since the GB. It is better late than never.
4x 4mm jet in manifold and 1x 0.4mm before throttle. can the jet be further away from the throttle? With the FMIC, you can place the 0.4mm at the exit of the IC to allow better intercooling when the air and water is mixed earlier.
You will also need a check valve after the split between the 4-port manifold and the single jet. This arragement is to prevent water communtating between the engine vacuum (4 port) and the FMIC jet (non-vacuum).
