Default Re: Nissan Pulsar GTI-R

Right, I've been recalculating:

4x444cc injectors.
Use the 15% figure so I'm at the top of 100% water and the bottom of 50%
Gives me ~290cc/min

1.2 bar ~ 17.5psi
My base pressure is 100psi on the 1s
So my x-axis is ~83psi

I want one jet that's between a 0.8mm and a 0.9mm?
...or do I want a 0.6mm before the plenum/intake maifold and a 0.3mm just in front of the turbo? - I like the idea of improving the compressor efficiency, and it seems to me that a smaller injection is less likely to give the big droplets that may damage the blades.

I think I'm going to need some spare parts to put this together? - With all due respect, can I just order the hoses and quick-fit connectors from John Guest? That's where I get similar plumbing fittings for my fridge.
