255 low pressure or high pressure?

Wich one is better for my turbo set up, trying to run 12-15 psi.
I have 450 cc dsm injectors and a resistor box.

Also this car is my daily driver, do you recommend 2.5 or 3" exhaust and down pipe??, I want to keep my a/c, I have an apexi turbo kit.

what turbo? chances are you can run the stock fuel pump without and issues...

DP and exhaust: if you can fit 3", go for it

If it was me, I'd upgrade the pump to be on the safe side. The bigger exhaust you can run with the turbo the better. It just all depends on how the turbo's mounted to whether or not you can run a 3" dp or not and keep the a/c.

that one I'm not sure of unfortunately :lol:. I have the 255 in mine, but it came with the boost upgrade when I had my jrsc. So I don't know which one I have.

I don't think it really matters because you have a fuel pressure regulator that sets the pressure where it counts. Maybe check with walbro?

^^^good read.

With your setup you would be alright with a 190lph............but you could run a 255 if you plan to upgrade.

Low pressure will be fine. thats what i bought and i am shooting for 300whp.
