If you are going for a twin nozzle set up permanently, I can narrow down the 2d's diagnostic window but require some playing around. YOu car is equipped with a knock sensor, I wouldn't get too comncerned, provided the HOM is not going to be taken away after all the other mods.
If you have a priming pump pushing the AM pump, you can get almost 550cc/min, you can run 4x 0.3mm and may be 1x 0.5mm jet immediately aftyer the intercooler.
The 0.3mm jet flows 75cc/min. at 6bar.

PS, whilst you are building the engien, why not put some brass adaptor in place and plug them up for future use.
Here is what they look like just in case yopu haven't seen them before. It come with a M8 blanking plug.
