Background: Almost finished with turbo lsvtec build up and have fuel system questions. The motor will be fully built @9:1 compression and a t3/to4e turbo. I'm planning on 350 to 400whp for the track and I was wondering about my fuel system. I have hondata 2b and I plan on running 720 cc injectors when I'm turbo.

Question: I have a walbro 255lph intank pump and a MSD inline pump both not installed yet and I am wondering if I need to use both and if these fuel pumps will support my fuel needs for the power I want to make.

 

for hondata all you need is the intank pump. good luck tiger. and about 14 to 18 psi boost. in my opinion. take it for what its worth. hondata oh and get the 3 bar map sensor
