Iownastang · December 9th, 2007, 08:54 PM

whar are your mods and 25lbers with any mods and a tuirbo are way to little and that fuel pump,put in a 255

Speedstang302 · December 9th, 2007, 08:57 PM

yeah who sells 25lbers...with an turbo you're talking bout 60lbers..and def an 255lph pump...stock is like 80 something...155lph is way too small

with a turbo on a stock engine you'll need "AT LEAST" 42 lbs/hr injectors..And you need a high pressure 255lph pump...

this car is my daily driver and like to add a turbo. if i keep my foot out of it what am i looking at for mpg my car is complete stock right now

For that matter, what is a 155 lph pump? Is that something they made in the 80s?

I have heard that out of the gas at 75 or so and 3.55 gears, mpg is around 20-25. just what I heard.

60lbers, on a stock engine with a mild turbo setup? Thats way to big of an injector. An injector that big can support 700hp.. which is way outta the stock blocks league. Hell, even a 42lb/hr injector is big for a stock blocked build. A 36lb injector would be just fine for 400rwhp, and there would still be some leg room with that. Stock 5.0 pump is 88lph. A 190lph will feed enough fuel for more than 400hp.. so theres no NEED for a 255.

Just because people use a 42lb injector, doesnt mean you need one. Most people run bigger, to stay safe and for future modifications. Thats okay, but assuming hes just going to keep it stock for now and drive... that means it needs to be reliable and stay alive. Spend less money, on what works. 36lbers... and a 190lph can tickle the limits of the stock block, why spend more money, when you dont need too?
