24 valve w/p series pump

[SixShooter]

I forgot who has the dodge with 24 valves but has the old p7100 pump on it. What was done to convert it over, and how does it drive? Before I found this group I thought about that idea and cummins said it was impossible HA HA proved wrong and I even thought of the C 8. 3 in the dodge and they said that was impossible but if a Phord can do it than Dodge can do it better.

 

[Evan A. Beck]

I have seen the 24V with the P7100 on it. LOTS of work needed to be done... New injector lines, fuel supply & return lines, timing cover, and mounting for the pump all has to be made. Yeah, it can be done. Yeah, it creates a LETHAL setup. And yeah, it is expensive. Worth it? Probably not, but it is really cool!

Evan, how about starting with a 12-valve and slapping on a 24v head? That way you wouldn't have to mess with electronics or mounting the pump. Then you should only have the injection lines and tweaking the pump to deal with.

If you start with a late model truck, you are kind of stuck with it.
P pump on 24 is only way to fly when original pump fails.

There are dozens, if not hundreds of these out there already.

I heard a pump shop say the electronic pump on your overvalved Cummins is WORSE than the old 6. 2 pumps!
Fighten words!

I've researched this one alot. .
its easiest to do the 12 valve p pump to the 24 valve head, the problem is you need to change pistons, the 12 has a offset camber compaired to the 24 center combustion chamber. That is the most of the work. The just bolts on, nobodys told me how bad it would be to just put the head on stock pistons but its not a good idea. Next issue is you have to use 24 valve injectors of course but they are smaller(stage 4's) than the biggest 12's (370's extrude honed to stage 6's) then the last thing is fuel lines, I've been told it would be all the bad to make them, around 400 bucks, but people that make these already like Enterprize engines sell them for around 1000.
Another benifiet is the guages still work in pre 98. 5's but would not in the later versions with the opposite construction.
just my 2 cents thow. good luck

That's the set up I have on my engine. The reason I went with this set-up other than the obvious power/reliability issue is to be able to achieve higher RPM's without the rapid decline in torque as commonly seen with other set-ups. The retrofitting was done at Schied Diesel in Effinham-IL and the work is meticulous. My opinion is it was well worth it for my application as now I can run the engine at around 4000 Rpm's for prolonged periods of time without any worries about running out of power.

Hadi, I'm told there are five engines at Scheid getting conversions, that true?

Maybe you could give us an idea what the cost would be for such a task #ad

 

[hadi]

Yes, all those are being converted before they come down here(TX)and find a cosy home in a Hummer.

My 6, the piston dish correlates to the injector pattern, not the pump. You only change pistons to match the nozzle spray pattern... T

hey hadi,
Do you think we could meet so I could see this excellent engine? I would like to see what the mighty Cummins looks like in a Hummer. Time and place up to you, I am free every night from 7 on except for wensday. Hope we can get together.

 

[Steve St.Laurent]

When I was at the Scheid rally last fall they had a 24v truck there with a P7100 on it. They were quoting $4500 to do the conversion. The Scheid guy that was at the truck didn't know if that took care of the gauges or not though. The gauges on 24v trucks run off the ECM.

[Evan A. Beck]

Easiest thing to do is take a 12V 98, and swap in a 24V with a P7100 pump on it. Not very cost-effective though.

A different route is to take the 98 12V gauge cluster and put it on a P7100 24V engine. That way, the gauges are all mechanical, or through the PCM.

Guys,
Maybe i am not reading the post properly, but why don't you just put the 24 valve head on the old 12v engine??? I know you would need to change pistons also, but... . no ecm to fool.

Why? Because those of us with late model trucks, built after 98. 5, have a reliability issue with the VP44 pump that comes on 24 Valve engines. If you had a relatively NEW truck, would YOU want to pull the 24Valve block, and put in an old rebuilt 12Valve engine, just to get the P7100 pump? I think not !!!! Common sense says if just the pump can be changed, that's the way to go.
The obvious answer is to call Scheid's, and get some EXPERIENCED and KNOWLEDGEABLE answers, rather than a lot of speculation about swapping entire engines.

Tom:

I forgot to tell you. I drove Mike Wood's
96' Dodge CTD with the 24 valve/P7100
pump engine when I was at "Scheid Diesel"
in January.

It is very fast and to my knowledge he
has no problems with it. Like "hadi" said
"the work is meticulous!"

thanks, John_P... . I'm working on contacting Scheid, among other people, concerning parts, prices, and techniques. If the scope of the project is way beyond my means in terms of time, and special tools, experience, etc. I would have no problem trusting Scheid to do the work. Other than the pump timing, I have yet to find any part of the project that I couldn't accomplish on my own, with the assistance of certain friends & family...
Information, information, on a quest for TECHNICAL information... I'm getting there #ad
