So the time has come to do glow plugs and injectors on my F350 and going to do the Excursion too. I've researched and will be staying with stock split shot injectors for several reasons. I have a spare low mileage set I'll be taking apart, cleaning up, and installing new parts like internal o-rings & springs so I won't have much down time. In my research I can take these stock 140cc injectors and install new 30% nozzles but they aren't cheap and looking at another route...plus the stock nozzles are better for atomization of the fuel. Would there be an advantage to making the injector into a 160cc unit...
How many miles on them? I would be tempted to just leave them be, do new external orings and run them
The wife's Excursion has 250k and it's been run out of fuel several times...these will probably get swapped and shelved. Her truck was getting 20+ on the highway but dropped off in the last year. I did find a couple loose loose clamps on the hoses below the spider a week or so ago and the power is back...hopefully the mileage is too. My F350 has 200k and is running strong with no issues unless it's below 50*, so I may just do glow plugs and shim them if need be. If I have to pull them for external orings, I'm tearing into them to do internal orings. The low mileage set has been sitting on the shelf for years so I'll have to get into them internally anyway, and just debating on either cutting .6mm off the intensifier, install an intensifier out of a 180cc unit, or leave them be. The way I understand the 140cc versus 160cc with stock nozzles is it may not need the extra cc of fuel even with a hot tune and/or turbo upgrade.
gotchya, I am to the point now with both the manners of stock splits, and the increasing emissions pressure, that I find it hard to want anything besides stock splits.
I am one who if I am pulling injectors and am putting time or money into them, then they will just go to a builder for new parts and dialing in on the bench. I figured thats the most guaranteed way to not waste time with continued messing with them. (though you have seen me proved wrong with that theory..)
In my humble opinion, don't fix it until it is broken. Only you know when enough is enough and when more is too much. A while back I replied in a thread about 160cc split shot injectors. The quote below was my response.
When I bought my truck nearly a decade ago to be a hard working tow pig, I had efficiency, longevity and reliability in mind. Last summer we towed our 5th wheel from GA to ID and back reaching a peak altitude of 8,900'. At 18,000 - 18,500 lbs GCVW I achieved 12.3 MPG's average over the 5,500 mile trip.
I have 3.73 gears on a 4x4 platform, 265/75R16 tires and run a PHP 65 HP tune on 265,000 mile stock AD injectors and HPOP. I have a T4 kit with a Borg Warner SX-E 363/68/.91 turbo, but similar results are attainable through the inventory of parts KC offers.
If that isn't reliability, longevity and efficiency, then I don't know what is. I am NOT interested in 25 - 50 HP more and I live in GA where I can do whatever I like to my truck.
Don't fix it until it is broke... Decide when enough is enough with your CA requirements in mind...
When it comes time for new injectors, I will go with stock AD's as I don't see the need to add 25 - 50 HP. Why throw a variable in a well functioning system... Especially since I drive/tow 65 MPH and like I have nowhere to be.
What works well for my situation and use is not suited for everyone, and that is OK. Your choice, choose wisely!
Like Eric, the writing is on the wall regarding the Eeeee - Peeee - Aye and their overreaching tendencies. We have seen this coming down the road for a while now and recently the bus ran over 1023. Many shops have been shut down, fined and some jail time for a select few. Who knows about our dinosaurs and what will happen.
If I had good running conditions, behavior and MPG's with a stock injector, I would stick with that. Some people say I don't know what I am missing by not going with bigger injectors, but I can honestly say I don't desire anything else out of my 23 year old diesel truck. If I do or did, I would be looking at selling and going to a 2017+ 6.7L PSD. I was dead set on 160/80 or /30 injectors until I got my stock 265,000 mile injectors and HPOP dialed in. Now, there is no way I am going bigger in the injector category. I might go with a stage 2 HPOP, but most likely just get a Bosch OEM replacement. Who knows though, perhaps I will be lucky and get 500,000 miles out of my tired and hard working injectors.
You are a brave soul performing surgery on those injectors yourself. You sound like you know what you are doing and I have seen some of your previous work. The only person I know of that successfully operated on his own injectors was Finnishstroker. I and many others look forward to your thread and as many pictures and details you wish to share with us.
my '02 7.3L Excursion is box stock, except for the Alternator.
it pulls just fine at 65 mph, or 1850 rpm.....
I could care less about the joker who screams by me at 85 pulling 22,500 lbs of 35' long RV... **** on him...
my '02 pulled a farm tractor from Utah to Oklahoma and gave me 15.3ish for that trip, and I purposely went over the Rockies because I had not seen them since 1972
it has 285/75/R16 AT tires on it, el cheapo "Americus" brand
I've received and read your PM and was going to response it...
Didn't meant to be ignorant or disrespectful by not answering,simply forgot to answer..
I will try to get back to you by the end of the week.
By no means are you being ignorant or disrespectful...just figured it might be a distance country gap. Thank you for chiming in, acknowledging it, and looking forward to your response...
I own three 7.3's. I installed 160/0's into the newest member of my trio within the last year. I unfortunately had a pretty major tuning headache to work through with this particular truck. Its runs awesome now, zero complaints. If I had to do it over, I would've gone back with stock injectors. My other two trucks will be new stock, or stock rebuilds if/when the time comes. I DO NOT want to rely on anyone or anything other than stock tuning to make my truck behave properly. Too many variables for my liking.

I can agree completely.
I wanna play with 238/80 and what not someday. But have decided if I do, it will be on a truck meant for play, and not my centurion

In the long list of mods in your signature, there is no mention of bellowed up-pipes. I don't know if you have them installed, but if not, I can say that lack of good fuel economy can be related to leaking up-pipes. I gained a full 1-1.5 mpg just by installing bellowed pipes.

I recommend get new. Buy once, cry once. Well worth the extra money.

Yes, the Excursion will get a turbo 360 kit with a new wheel and stainless bellowed up pipes. I've been looking at billet turbo wheels from the 4x4 to a 7x7 that will run with the ais going on. I know the up pipes are leaking some but I think most of the leak was in the loose...as in finger tight...clamps on the boots under the spider going into the plenums. I had noticed a loss of power and a whining noise in the upper rpm's I've been chasing for a bit, and after I went over all the clamps the power is back with no more whining. My F350 had the turbo, pedestal, etc. replaced about 130k ago and I believe the donut gaskets too. I don't believe it has any leaks now and runs strong. Depending on what happens with the wheel I decide on for the Excursion, will dictate if I decide to put a new wheel on the F350...

I'll just say that the donuts are leaky right out of the box and it only goes downhill from there. Mine were leaking and I had to wrench them out of the hole. Lot of people state that they just fell out. Bellowed up-pipes seal up completely so that there are no exhaust (read that as boost) leaks whatsoever and you'll be able to be assured of excellent performance from that day forward. At least on the exhaust side, anyway.
