Default High Flow Fuel Pump for NA Baja?

Hi all,
was wondering if there's an benefit from using a high flow fuel pump on an NA baja. I currently have a PP6 from rallitek and have an air intake, am about to do a cat back from TWE, and hopefully the headers and cat at the end of the year. Wondering if replacing the fuel pump will add any extra umph...

I wouldnt think that it would do much for a NA baja especially with stock injectors and a stock top end. I think the money would be better off spent on pullys maybe

already replaced the crank and alt pully. waiting for a swap on the wrong part for the ps pulley... hence the question.... guess i could extend it... is it also feasable to swap out the injectors as well? would it do any good in an n/a setup?

well in my opinion the more fuel you pour to it the more air it needs bigger intake bigger throttle body bigger valves or ported heads I would think the stock fuel pump is good untill you make tons more HP for example I own a sporttrac and modified it with a chip,MAF,throttle body, Borla CAT back, pulleys, injectors,and conical filter which dyno verified bumped 35 RHP and did not need a new fuel pump. as well as my baja which is unichip'ed downpiped, manual boost controller CAI, turboback 3" and its on the edge for needing a fuel pump prob do that next though.

What kind of performance increases are you experiencing with the mods you have so far?

actually not really sure. Guess I just want it to have a bit more umph. If i can get it
to 200hp from the stock 165, i'll be happy. I'm already happy w/ the bits i've added to this point, as it just makes the car more fun to drive, and the changes have been noticable. Very glad I went w/ the engine mgmt, as it smoothed out the acceleration in a noticable way. Hoping that I'll notice a bit more once the cat back get's put on.

You probably wouldnt see any gain from a fuel pump at this point. Infact if you swapped out the regulator and puel pump and ran higher pressure it would probably just be rich and boggy. Look into some cams and headwork first. If you are worried about the fuel pump for some odd reason, you can pick up walbro 225lph pumps for around 100 bucks.
