I have an 06 mr w TB exhaust, a test pipe, apexi int & induction box, will have a Nisei or ets licp, I have a hallman rx mbc and aem uego WB and boost gauge. I am cranking up the boost to 24 peak hopefully tapered to 20 and will get a tune thru speedfactory. Do I need fuel mods, ie injectors and or pump for this set up? I know the ix's have better fuel but want to make sure before I show up to the tuner with no gas lol

 

Injectors no. As for fuel pump, the IX pump is good, but I would upgrade it now if future mods will come into play.

It's cheap enough to get anyway.

Good Luck

 

But as of right now I don't need the pump to run 24 psi

 

Upgrade your fuel pump. It's cheap insurance and easy to do.

 

I installed my Walbro last week and before I did I was logging fuel pressure. My stock IX pump was dropping ~4psi fuel pressure at 22psi of boost. Installed the Walbro and it now holds pressure to red line. You really need to have the ability to monitor fuel pressure to answer your question.

Based on what I saw, you should probably add the pump.

 

Thanks for the info. So when u installed it do u have to run the tank dry to do it and will the walbro behave the way the stocker will until I get a tune. I will change it myself but will have to drive the car two hours to the tuner?

 

Subscibed

 

Why's the fuel pump insurance? I thought the ix pump was good for 350 whp

 

I'll assume you're going to tune on Pump 93 Octane? If that's the fuel being tuned for, you will not need a Walbro for 24psi. Anything beyond this point will require an upgraded pump for more fuel.

 

The lower the fuel level the better. Try to not have more the 1/4 tank of fuel for the install.

 

What mods are on your Evo, 240Z TwinTurbo?
