Ready to pull the trigger on injectors. Last minute advice needed.

[Frostbite]

Ok, yes I am slow but, I have new glow plugs in the shop and I have read several sets of instructions on how to change the injectors.

I'm fairly certain I will be going with the Stage 1.5 injectors from Jim at Rosewood Diesel. I have a very unoffical goal of 400 hp and most of the supporting mods are done for this step (see my signature block for listing). My question is, do I ask Jim for 160cc 30% over injectors, 175/cc 30% over or 180cc 30% over injectors?

The stage 1.5 injectors appeal to me because they claim to provide better fuel economy, more power and allow me to maintain some level of sanity. I am not considering them but, Swamps offers a 175/146 injector, what does the 146 mean? Not 146 % over stock? The reason I ask is, they claim 2-3 mpg over stock injectors.

Would my BB in the FPR provide plenty of fuel to run these injectors while towing in the mountians?

Would a D66 be necessary immediately after installing these injectors?

If I drive sensibily, can I use this setup with the stock transission for a while until I get my 6.0 torque converter and BTS valve body?

Am I barking up the wrong tree? No I am not intersted in hybrids. My truck will be for dump runs, towing my pickup camper and boat or my four place snowmobile trailer in the winter. I do tow in the mountains but, increased fuel economy and reliability are more important to me than raw horse power numbers. I have no plans to run my truck across a dyno.

Would I be better off going with stage 1 injectors (160cc with stock nozzles)? Or I could go with 175 or 180cc and stay with stock nozzles. Would the stock nozzles allow the full 180ccs of fuel available per injection cycle to used?

I bought my Tony Wildman chip from Raul at Stealth Diesel. Can I send it back to them for a reburn after while the injectors are being done or do I have to send it Tony for the reburn? Do you guys have any advice on what the best tunes to order might be with my new injectors? I currently have high idle (so I can warm my truck when snowmobiling), daily driver, tow, heavy tow, street and extreme.

Any advice would be greatly appreciated.

The 175/146 is 175cc and stock nozzles

Really.............. I had no idea.

These are the injectors that claim the 2-3 MPG gain. Now, I am wondering if 30% over nozzles drop the potential mileage gains if the truck is driven in a sane fashion?

as for your question on fuel..... your stock fuel will fun thoes injectors but keep in the back of your mind, any time it drops below 50psi you are slowly destroying your injectors so an E-fuel upgrade will be good and you will love it once its in!! so im told, its on my list to do

[yngbuck19]

E fuel is awesome that cam driven piece of junk is worthless

Ok, I will add that to the list. I will have to do some searching and research how it's done.

What about all the the other questions I asked? Surely, someone must have some answers..............

IMO go with 80% or 100% nozzles, instead of 30%. DO NOT go with stock nozzles, there is no point in ever leaving a stock nozzle on a non-stock injector. I'm running 175/100%s on stock tuning, getting 16.3mpg's doing 70 with a headwind and a 7.3 in the bed. Plus i had no problem passing cars or getting up to speed with traffic, all of which my stock 7.3hated with any load and a wind.

A D66 is not needed as long as you don't go much past 30-35psi, i'm hitting 29 right now. Same with a trans, don't run it hard until you have some mods. But it could go out today, or in a couple years, no real way to tell. And TW tunes are free re-burns for life.

Thanks Jimmy.

I was looking at the Farmer's Diesel 200cc/100% over injectors but, I was told; "why would you do that, why not just go to hybrids".

However, I certainly don't want to get carried away and have to buy a BTS transmission, new up pipes and a huge turbo to be able to run larger injectors.

If i had the cash i'd go hybrids no doubt, but if your looking at "small" 2's the nozzle prices are the same so it wouldn't be any more to go to 100% which would make more power cooler, and cleaner than smaller nozzles.

With 2's or hybrids, or really any injector it comes down to tuning and how you drive the thing. I could go out and get a set of 400/300%'s and drive it for a while on a stock truck no problem. But one hard run and i'd have pieces of the turbo in the hood and half a transmission on the ground.

But honestly, if you are even looking at any sort of mod, be prepared to get a trans at any moment. You don't have to drop $5k+ on a BTS though, there's quite a few cheaper options out there that will suit a lightly modded truck just fine.

Budget stage 1 are $500. About 325 hp

Budget stage 1.5 at $885 About 350 hp adds new nozzles

Budget stage 2 at $885 About 400 hp adds new nozzles

Premium stage 1, 1.5 or 2 are $1235. Overhaulsed with new nozzles, plungers and barrels.

Premium stage 2.5 for another $400 ($1,600 vs. $1235) I could go with 200cc single shot hybrids with 30% over nozzles that with supporting mods would reach my 400hp goal.

Premium stage 3 for $50 more money ($1650) I could go with 238cc 100% over and be capable of 500 hp and tune them down with programing.

But no............ I do not want to scatter parts all over the road.
