Re:stock injectors with turbo
 

You can use stock injectors up to about 5-6psi..

You do realize you're going to damage your stock fuel pump in doing so?

Say you get a 12:1 ratio FMU.. for every 1 psi of boost, you're going to raise your fuel pressure, 12 psi. Stock is say 42psi @ 5psi boost 42 + (5 * 12) = 82psi.. your stock fuel pump will fail at 120psi.

That was only a calculation of idle fuel pressure. I can't remember the rate of increase in fuel pressure at NA WOT.. I believe it's 60psi.. So, with the same idea, 12:1 FMU will be pushing your fuel pumps limit at 5psi of boost.

So, you counter that remark with, "I'll buy a better fuel pump."

Why? When you can get a set of injectors, cheaper, and run your boost correctly, and safely, up to your 9psi... you're just not making sense. ::)

Re:stock injectors with turbo
 

yeah; i bought a set of 450cc dsm's for a whopping $25 shipped.

i also pushed my 240's with about 5psi of boost for a few days before i got the 450's...
i'm sure my duty cycles were over 100% and those injectors wouldn't have lasted long at all but i needed boost and i sold my FMU.
