at minimum you'll need the blue injectors.
you'll want to weigh your options here:
purchase blue or black injectors (pre-machined for fitment) + 650 pulley (pre-machined) from ESS with the accompanying tune (they have different tunes based on injector size). it'll be an expensive package.
OR
purchase off the shelf bosch green injectors + spacers + your own 94mm pulley (will need to machine for correct offset) + green injector tune from BPM. cheaper route.
