Has anyone heard anything about high flow injectors on a 300 (i believe they are 19lbs, but dont quote me on that). what will this do for me if anything or should i stick with a set of stock ones? My current ones have about 185,000 on them and i think it might be time to replace them??

 

Don't waste your money unless you are planning some modifications.

 

what kind of mods would i need to do to make them worht while?

 

comp or crane cam and headwork basically.

 

And exhaust and you'll have to adapt an adjustable fuel pressure regulator from a 5.0 to work. After all that a computer chip might be a good idea to make sure you get your money's worth out of all the rest.

 

Custom intake will help too

 

thanks for the info guys, i guess im gonna stick with the stock ones. ebay has a set of bosch ones for 160 bucks. Is that a good deal?

 

Not really. I think I paid $25 for mine and got a set of 8.

 

Check out RC Engineering or Cruizinperformance about getting your injectors cleaned. A friend of mine builds and rebuilds 3-series BMW's and has used both. He's seen LARGE improvements on all sets he's had processed. When he gets them back, he has data logs on flow patterns and rates, so he knows their all flowing within a certain percentage of each other.

 

summit racing has them in 15, 17, 19 and 21 lbs./hr, i was going to order a set of 19lbs./hr tonight along with my ignition, cam, and headers, and was going to have a chip/ecu programed to what mods i have.

 

Hey swamp,
I have several mods on my 92 and the plugs are showing lean so the 19's are in the works for me too. A friend of my sons gave me a set from his mustang and they are orange. The ones in my truck are orange too but a slightly lighter colored orange. I have been trying to find p/n to find out if maybe I already have 19s but so far no luck. Do you have any ideas on this one?
I was figuring hp and outputs at different pressures and found I need about #21 or #22 so do think there is a pretty good chance the #19s will work with the stock regulator?
You mentioned getting a chip done based on your mods, can this be done like that or does it take a dyno pull to get it right?
Sorry to ask all this but I can't seem to find the info. Sure would appreciate any help you can give.

Ricahrd

 

get the #19s from a 92 ish or newer v-8, newer design and better spray pattern.

oh and with the stock regulator u would be pushin them injectors and flooding the engine. u need the 5.0 regulator. set the fuel pressure about 50 (needs 45-60) and ur good. BTW, stock 14s are being pushed to 17 with some kinda duty cycle calculations accoring to strangeranger...

 

is there a number on the injectors?

there are a few places that you can call up and tell them the specs on the cam, and other mods and they will custom make the chip for you.
my setup is going to need quite abit more power so I'm doing the following, deck the block, mill head with major valve work, cam, injectors, header, auto tranny conversion, ignition setup, and really thinking about doing the 460 throttle body.

Here is what I have now
1995 F-150
solid axle conversion with 14" lift
5:13 gears with posi front and rear
18x39.5-15 swampers
true dual exhaust, no cats or mufflers (too loud but great for what I do)
and a bunch of cosmetic goodies

 

Thanks for the reply,
The number as well as I can see it on # 1 is:FIZE-B or 8 4 ?(covered by the connector. Number 2 is a different p/n, it appears to be:F 0 or 9 F 5 or 6 3 ??? no dashes. I need to get a mirror and flashlight then stand on my head.
I have a 92 super with a m5od (started as my wifes truck then I inherited it). Hated it at first but now I love it. Had intended to give it to my son when I got a new one but I liked my old 6 better than the new one so we switched. The new one was 4x4 and mine is not, wish it was.
A long time ago I decided 200k was the point I would rebuild and did. The machine shop told me I had less than .010 cylinder wall wear and the crank did not even need turning. Says a lot. I have a fresh engine now I am trying to do the final touches on, bigger injectors is one of them.
Engine
.030 over bore
Crane truckmaster
.040 off the head
Balanced
Hyperutectic pistons
3 angle valve job
bowels opened up
Deck was only .011 in the hole so left it-not sure if this was the best call but too late now.
Left the EFI manafolds and a single 2 1/2" thru a magnaflow
3:08 rear and 30X950 (lots of highway)
Runs good but seems to run low on power between 75 and 80. Gas mileage could be better too, a little over 15 overal. Seems city is not a whole lot different
The truck looks pretty good other than the parking lot dings and a little surface rust in a few places. Plans are to take it back to showroom. Beats doing "Honey Do's".

 

how do you like the crane cam? I'm kind of stuck when choosing a cam, hydraulic or mechanical, lift, duration, etc....
i have everything figured out but the cam, and tranny. there is very little information that i can find on which one is better for the efi, only a bunch of different opinions from people who havent actualy used any of them.
I find a lot of helpful information on this website but it would be better if there was another section for the EFI inline 6's instead of having all the useful info hidden/mixed in with all the non-EFI info, it would stop alot of the repeated questions too
