I don't have the answer but I'm just curious why you need to upgrade your fuel pump.

I'm sure you have a plan but I'm unable to connect the dots. How will you create more hp by simply pumping more fuel when you can't cramp more air? Won't you just be running rich and ruin your cats? And how will the OEM injectors handle the high flow?

The high pressure fuel pump on Mazda’s SkyActiv-G 2.5L NA already has very high fuel pressure, rated at least 2176 psi with full throttle.

Just curious, for the intake, are you going to a custom fabricated sheet metal? Also, who are you getting to port your head? Who you choose to do it is the difference between making power and not. Choose wisely.

This is a custom sheet metal intake.
Something tells me you're not quite sure what you're trying to accomplish here. You may want to drop back, punt, and do some research, talk to engine builders, and get a cohesive plan together before you go spending a bunch of money on parts that won't work well together. A reputable engine builder will know exactly what you need to accomplish whatever your goals are.
Do this, and your pocketbook will thank you.

I’m not talking about that in this thread my friend, I’m talking about fuel pumps. I don’t really give a crap what you have to say about other topics. If you don’t want to contribute to what the thread is about why are you posting?

But you absolutely are!
"I’m going to be putting a few other upgrades: aftermarket intake and exhaust, cams, a turbo, and it will be chipped and tuned after that."
Everything in an engine works as a system. When you get one part of the system out of balance, then you lose efficiency. When you lose efficiency, you lose horsepower.
You really, really need to talk to someone who knows exactly what they are doing.
