ok so yea here is my issue i have a 95 s14 stock KA maunal trans. The problem is when i am playing around and bounce ot off the rev limiter its dies like the fuel has cut off or something. In order for it to start back i have to turn the car completely off then back on. I am thinking it is the fuel pump not pushing enuf fuel to the car aka dieing fuel pump. I know its not the filter since it is new pretty sure its not the injectores cause the motor is 2 years old and seafoam every 6 months. So am i on the right track or not?

You shouldn't be touching the limiter with a KA in the first place.

You are planning on building your engine yet you can't figure out where to start on your own? I have a picture in my head of what you look like. It isn't good

If your building a motor why are you considering a stock fueling system.

i am in no way considering a stock fuel system im asking if the pump is going bad or what cause until it gets tore down and redone i want it to run perfect but i will be changing to a walboro with 550 nismos and a water meth setup keeping the side feed style cause im not going crazy with power just a decent mild build
