What size injectors should i go with?

[TurboGeoff]

I will soon be upgrading to a Holset HX35 Turbo from my Evo 16g, what injectors would be best suited for this turbo? Also, what size fuel pump will i need?

Currently i have an SAFC2, Denso 180lph pump, 2g mas, and i will be getting a keydiver chip for my setup when i determine it.

That all depends on how much boost you plan on running with your e16g. With stock injectors and stock pump, I can safely boost around 14-15psi. A 190lph pump will hold most people for awhile, so your 180 should be ok too. If you don't plan on going crazy on boost past 15psi, I'd go with either 550 or 650. Make sure you have a logger when you are upping boost though, indespensible tool.

ill be using the holset, not the evo 16g, ill be running pump gas, so 91 octane, water injection and a fmic. prolly 20 psi. i want 400whp

i doubt the 3000gt pump will be enough.

im not a newbie and i have a logger.

id say at least 660's but if you go any bigger you will need a different tuning tool than the safc2 because it cannot really be used with any degree of accuracy with 720's or larger.. also if you go any bigger than the 660s you will need a larger fuel pump so id say 660's just for the convinience

i was planning on a keydiver stage 3 chip to be able to run 780s, and fine-tune with the safc2, think that would work ok?

I would say at least 750cc injectors because Im sure you will turn the boost up sometime. on a side note, I have the fic 750cc and a keydiver chip and tune is almost perfect. I had to lean the idle up (1000rpm low throttle) 8% but so far, everything else is zeroed out. Remember, its better to go too big than to go too small.
