im upgrading my blacktop to a 2871r .64, z32 maf and nistune. I'm looking at a set of 740cc hks injectors, is this overkill for my setup and will these even be in a good duty cycle for 18-19 lbs on that turbo?

search for an injector size chart, it will ask you for a horsepower goal, which you need to set yourself, and the duty cycle you want to run on the injectors.

740s are perfect for that setup.

MR_Nissan, If you were going to dd that setup with the 740cc injectors how much boost would you be running?
