ok I have a T3 turbo and I want to run 6 psi on my ECOTEC

what do I need?

FPR (wich to buy?)
FMU ?
bigger injectors? size?
better fuel pump?

OR

a SDS?

and what if I want to upgrade to 8 psi later?

thanks

k........
fpr i dont know for the ecotec. search.
fmu the 2025 cartech one is very simple to install and should work very well. I got mine from lightningmotorsports.com. Pretty good price.
Injectors. for only 6lbs I suppose some 35#around 330cc or so should do. Something like that.

Alright, the fuel pump is a def though ( not like the fmu isn't but you get what i'm saying) autoperformanceengineering.com has the walbro 255lph pumps. Look under applications and get the fpg0003 or something like that. The high volume high pressure one. Pretty damn good price for a fuel pump.

will the 2022 cartech FMU work??

i don't know.
Go to the website and read about it. It might be one of the N/A ones.
Do a search here on it and see if anyone else is running it.

someone here run 6 psi with stock injectors?

I'm sure somebody is, but it's definately not a good idea. Stock injectors were designed to fuel a stock motor, not a boosted one.
