just wondering what the biggest sticks you can go with having stock turbo. i have heard 75hp is about as big as you want to go . true or fasle? please chime in. plus what about the RV275 injectors? i don't sled pull or race. just want a injector that will deliver more power but get o.k. milage and will not raise the roof with hot egts!!!!!!!!

I would give chris and jamie @ SDX a call for you injector questions/ goals.

That being said I really do not think there is a general size injector that is a "max" for the stock turbo.

i thought if your not pushing enough air then a larger injector does you no good but to roll alot of coal and have some really hot EGT'S.

Hot is a relative term.

well relatively speaking what would be the best injector that won't make it warm?

215s work pretty well. Really though the stock charger can't flow enough air to support a whole whole lot without seeing some impressive numbers on the gauge face. I know with mine when I pulled my plate out and fiddled with the for 2 minutes I could still wrap my gauge.

Agreed one mans "hot" is another mans "not bad".
I have had 2 96's that were basically twins except for how they were modded.
Same gears, trans, turbos, fuel plate and exhaust.
Truck 1.
Stock injectors and different delivery valves, but I don't know what delivery valves.
It would get very warm towing and the power came on hard and strong and smokey.
I had to get out of it on some hills, it was downright annoying.
Truck 2
140hp injectors and stock delivery valves....night and day difference.
The power is just as strong if not stronger but comes on much more manageably.
Temps are quite easy to keep in check, it will still smoke if I punch it from a dead stop but it clears up much quicker.

I would go with a used set of 90's or 140's and try to find a used turbo.
You can buy a plain new s300 rather economically.
It's when you get into buying the HTT and other branded S300's and such you get into the big money.
HX 35/40's hybrids can be had economically too.
They are sort of "old school" now but do work well.
Injectors aren't too bad about using more fuel....your right foot is whats bad about using more fuel.
With stock injectors you can mash it and it won't dump enough fuel to cause it to drop alot of mileage.
Bigger injectors WILL LOL

Th erv275 are 24v injectors, and if you have a maunal transmission (the 215hp pump) those injectors are decently size for your turbo, if you have an auto look for some 215hp injectors.

He's got a 180hp pump.

215 or 5x0.012 are about the highest you want to go on a stock holset

hotcummins's Sig:

its a 12valve with a few performance adders

The RV275's are a 24v injector and can not be used for a 12v truck.

Adding injector size will add temps and lower fuel milage some.

Anyone who tells you that they added bigger injectors and get better fuel milage is telling you a nice story.All that added black smoke out the pipe does not equal fuel milage.Your going to have to think about what you want to do with the truck,power or milage and then make your decision.The injector size and tunes for both are very different and if your on a limited budget like you are then this needs to be considered.......Andy

I have stock injectors and stock delivery valves. I get heat and black smoke just from them with little pump fiddling(no plate and afc adjustments which I still don't have adjusted right yet) and 19* of timing. I get 18.5mpg sometimes but on my last tank went down to 11 for some reason. Part of my problem might be the H1C that I have now, but it was free and I needed a charger.

I have no plate and havent messed with the afc much, stock 181 dv's, stock injectors, stock turbo and it will wrap the pyro pretty quickly, Lucas and I were messing with the timing a little bit and when we put the gauge on it it had slipped to 11 degrees bumpin her back up to 16.5 and see how it does. Should cool temps down a hair. If your on a budget go with some 215 injectors or just save your money till you can afford both the turbo and some good injectors.
