Injector question

[Archive]

A friend of mine has an 89 D250 and I was wondering if the 215 injectors I just removed from my 96 will work in his truck? He already said that he wants the turbo from mine when I install the hx40. Does he already have the hx35 on his. If so I think that he would be better of just going to the 16 housing rather then the stock waste gated 12 housing that I have now.

Tom, from what I've read in many past post, your injectors will not work in the 89. If I'm wrong, someone please correct me.

If they are the injectors I'm thinking of, with a sleave kit to fit the 9mm holes, those injectors may work. I am just getting injectors installed today and thats what they are doing, I just don't know if they are the same as yours. The shop and Piers both say that there are no guarentees with them as the pump becomes the limiting factor for fuel flow.
You're right about the 16cm housing. The wastegated versions are great, but have a little more drive pressure(back pressure). If you want instant boost, get the wastegated. But I don't drag race.
One guy posted that there wasn't much of a difference from the 18 to 16 in the '89s. Personal prefference.

The 215HP injectors really won't do much for an '89. Sorry to toss cold water here, but we've tried it. They are really clean running, but don't make gobs more horsepower in the earlier trucks.

I've put them in a couple of times, and the truck really ran good, but it was always combined with doing other work - pump and timing. Finally, I got a side-by-side comparison to stock nozzles, and there's no real horsepower gain.

If you didn't want horsepower gain, but lived in high altitude and wanted to cut smoke, I bet they would help a lot.

For me the upgraded injectors and the stock replacements were the same cost, so I thought I would try them... No big gain, no big deal. I had to replace them anyway. #ad

Thank you for the input. Moparguy I will be in contact with you. We are moving my parents starting this weekend so it may take a week or so to get back with you.

Power Wagon, Now I'm really confused. Is there a difference between the 89 engins and the 92& 93 engins. I guess I'm asking how you define an early model truck. I was under the impression from other threads that the 215HP injectors is a good though not extreem upgrade from the stock 140Hp injectors. I know that early trucks were not intercooled,Is that the only difference? If the 215s are not the ones to go to, Which ones are?And What year trucks need the adaptor for the injector holes and which don't?Just when I thought I had my plans mapped out, along comes this info and I go,WHAT?I know I can count on some one to clarify here. Thanks

Peleeguy, diesel emission standars changed in 1991 which forced cummins to change their engine that year. Some of these changes were adding the inter cooler, a different head casting with 7mm injector bores instead of the 9mm bore used in the 89 and 90 engines. The piston bowl geometry was changed along with larger piston pin bore bearing. The injector tips went from 9mm to 7mm. The oil pump drive ratio was changed to increase oil flow, the piston cooling nozzles have a larger diameter. The oil cooler has a larger surface area and the oil pressure regulator/oil pressure spring changed to increase the consistency of oil pressure regulation. All of this is covered in TDR issue 2.

In '89, the engine was introduced with 160HP. In '94, the automatic truck STILL had 160HP.

In '91, there was a head change, as was referred to above - it made the head more durable, too. The spray pattern was essentially unchanged, however. This coincided with the intercooler being added, and the exhaust housing being changed to a 21 CM2. In 1991, we had a large number of customer suddenly show up with new trucks, complaining about poor performance and milage, compared to the 89's and 90's they traded in. We did not know at the time about the turbo change... but if you timed it a bit different, and turned up fuel a bit, they'd run OK.

During the run from 89-93, the torque rating for the engine slowly crept from 396 ft-lbs to 415 or so.

On other difference. . The tube from the turbo to the intake on a non-intercooled engine is very small. Tube size was dramatically increased with the intercooler, and then increased again with the '94 models.

Injectors from the '94-up engines have very small holes, and use high peak injection pressures to help keep emissions low. The VE pump was not engineered to produce those pressures. Ergo, the earlier engines had larger hole nozzles.

These are a few of the obvious differences and changes that happened from '89 to present.

Thanks,Gentelmen, for the very interesting history lesson. From what I see it appears that I will need injectors that do not require pressure that my pump will not be able to furnish. The 215hp injectors do not appear to do this. I am sure that there are other injsctors that will. I guess I'll do a search to research the subject some more. Thanks Again.

Hey Preleeguy!

I had this very same discussion with Ted Jannetty when I was up getting my pump & injectors installed on my '92. He mentioned exactly what Power Wagon and the Gang is saying here in this thread, that our trucks are limited to which injectors we use because the VE cannot achieve the pumping pressures of the P7100 for the correct spray pattern.

There are a few choices out there for our trucks but I know of the BD High Output (40 HP) and an almost identical set sold by JRE thru a custom builder. Also I believe that DD & others have injectors that function well with the VE pumps.

Maybe "Old School" had the right idea trading up to a 12 valved P7100! Now only if he would of got the front axle w/ manual hubs, leaf springs and a NP 205 to go with it!

There are some drawbacks to the P7100. Namely, static timing. I think that the engine can be slightly more efficient with the VE, in spite of the lower injection pressures. However, the P7100 can seriously cram more fuel out than the VE ever dreamed of doing.

OTOH, the P7100 was designed to pump more fuel and last a LONG time.

Hey KEENO: And just when I had worked thru a 12 step program and a group hug therapy session to let go of the locking hubs and NP 205..... There you go bringing up the ghosts of Christmas past!
I guess I'd better start working on that. The P7100 seems to be good medicine though. Truly STOKED on the truck.

Hey Old School!

Sorry for dragging up all those old emotions, especially after all the extensive therapy sessions. I guess I just have "P" pump envy! It all began when I tried to compete with "Xanderbilt" and that awesome '92 W250 Powerhouse she purchased from you. My truck just doesn't seem to be as powerful as your old ride. Maybe things will be different after I install a 12cm2 housing!

The nice part is that she let's me drive her new truck sometimes... ... ... ... Keeno

KEENO: Glad to see you made it to the salt water with Xanderbilt. Hope you both caught your share of swell.
You're both the owners of some class 1st Gen trucks. I'm sure you consider yourself fortunate that you are "treated" to some wheel time in the Big Medicine '92.
Sure hope you're not getting spoiled with the seats and all.
I'm having a good time with the '98 "P", and am enjoying "bringing it up to the standards". I do miss my cap and Yakimas though. The new LEER is due in next week.

Best.
