Stock FPR and a 255 high pressure

[B005T3DT5i]

i recently bought PTE 880cc injectors for my talon. i dont have money for a AFPR but i do have money for a pump. i dont think that the 190 will flow enough fuel to feed the 880s. thats why im set on a 255 high pressure. so on that note dose anyone know what psi the fuel system is with the stock FPR and a 255 high pressure? that way i can install the pump and injectors and compensate for the higher fuel pressure in DSMlink.

PS:im running a FP 18g turbo.

Stock fuel pressure is set at 43psi. Your high pressure pump will overrun that though. With 880cc injectors I would wait to install it all until you get a FPR. It's not so much that it will hurt your car but you will have to compensate for it. I see you listed you have DSMLink so you should be fine to run it until you get a FPR.

1g 5spd pressure is 38.

But yes, you will overrun the stock regulator with that pump.

a 255 regular pump will flow alot of fuel, not sure if you need a HP version.

He drives a 2g though so his stock fuel pressure is 43psi. You will be fine with a HP pump. TONS of people on here run 255HP pumps with no FPR and run perfectly good tune. With the DSMLink you will be able to tune it quite well. Shouldn't be any problem.

doh! I got his pic mixed up with the one below it, sorry.

yes car will run, and maybe even ok, but not as well as it will if the pressure is even and steady.

I ran my car like that with an in-cockpit electric FP gage. There were zero ill effects of running a 255LPH HP pump over my rewired stealth TT pump. The pressure did raise 2 psi at an idle but never fluctuated from the +2psi.

I'd still wait, but then with my 1G and no FPR, I ended up killing a set of injectors. Was running at 43+ with vac, and it's only supposed to hit 36-38 without.

I'd still wait until you can get an AFPR, though.
