Hello members of Zdriver. My name is Caleb and I drive a 1986 Nissan/Datsun Z31 300zx. So, this vehicle is a recent purchase, and the plan is to not let it be a garage decoration. The plan is to do an E85 tune on it but there are some things I don't quite know yet. Number 1, what size are the fuel injectors? I've done some research on other forums and founds answers such as 259cc or 315cc. Second, done some more research for the E85 tune and have invested into possibly getting this *High-pressure fuel pump. * Now to accommodate the new fuel pump what size injectors are supposed to go with that? I have not ordered anything yet before I know for sure it's right. I posted the links to the High-pressure fuel pump and the E85 tuning kit below for feedback. Any knowledge on E85 tuning in general is much appreciated!
Also of course let me know what else I should be upgrading in the Fuel system for me to run this setup.
For those who are wondering why I'm upgrading my fueling system, I'm shooting to make 350whp, 400whp if possible, in the future and the fuel system is the first thing I'm upgrading.

Thank you everyone for the help! -Caleb
