p-pump conversion...?

[TxDieselKid]

Ok, so just wondering for the sake of thinking, what all parts WOULD be needed for this. I know a cam with a lobe for the pump is a must, and a timming case, and injector lines, and so one, but anybody care to tell more? I would like to have a nice list just to look over.



Email me if you want/need to, -- email address removed -- .

The only reason that you would need to change the cam is for the fuel pump. Why not just run an electric with a 7 psi regulator?

I've been wondering too, especially if you can get a deal on a good p-pump--isn't that the most expensive part?

On a P7100? Needs to be more like 25-30, for constant use like he is talking about an Aeromotive A1000 comes to mind! Andrew, call Al or Piers and ask them about a kit, I had heard from the NW Bombers they were looking into building a kit to sell and yes it would be high no doubt!

It figures...

Just as it looks like I may get the honor of hooking up the wire on your comp your looking for ways around it. Oh, well the grin on your face after I install the DTT goodies will be some solace.

Hey TDK,



Call Al or Piers for details. It is supposed to be very easy to do if you have the parts.



Piers charges 2500 in labor if you supply all of the parts.



Best bet is to buy a complete 12 valve motor and pull all of the parts.

I think some of you guys are missing the point of this post. It is not because I want to do it, well ok I do but it won't happen, I'm just trying to get some technial discusions about something other then trannys.



Just so happens that this is something that I think is cool to talk about, but would LOVE to have done also.



Now, anybody know of some other parts?



Andrew

TDK,



24 Valve injectors that match the injection pressures provided by the P7100.

Little plugs and what not to cover all the sensors not used by the mechanical engine.



Just make sure when you put it all together you dont forget to pierce the wire!!!

Jeez, I think there's more about that wire on this thread then there is about what parts are needed. Just because I have had the self control to wait, and most of you couldn't, dont' mean you should give me a hard time about it.

The first time my VP-44 goes out (out of warranty) I'm gonna do the P-7100 conversion. So far it works perfectly (no bombs). My question is this, do you get an eternal "check engine" light? What about the cruise control? My cruise is through the VP-44 (2001 late build). anyone done this?

 

[HoleshotHolset]

Threads like this make me so glad I already have a P-pump... .

Don't change just the pump. Put on that high flow correctly valved (yes, of course, the 12 valve) head.

 

[TxDieselKid]

Joe,

I don't think I'll win a debate with you, but why would I want to do that, when a Stage2 24v head from Piers will flow more then a Stage 3 12v head from him.

There are more parts involved than you are thnking. It is a major undertaking. There are some OEM parts that need modification to work in addition to your current list, along with more to add to your list. Technical know how on this conversion is very important when you get into it deep. Remember these guys that are doing it are not telling everything about the parts or the pitfalls.

The p-pump conversion has been around for awhile but some of the trucks run a little rough from what I hear so make sure you select the right p-pump. Its more costly then you think and more involved then you anticipate.

If you're going to tear down the motor that far you may as well do the rest because you're going to need it... . ie the head, cam, yada yada.

Change other parts to support the p-pump. Fuel lines lift pump etc.

Mechanical timing and fueling. The engine light is on all the time. No VP44 harness to plug into that ECM port. If you throw a code what is it?

The cruise control works fine, there's a little bit of a surge but otherwise its O. K. that may be another characteristic of the p-pump. Make sure those governor springs are adjusted so you can drive in traffic. If you run an hx40 these things fuel so hard off the bottom you'll probably go through a couple of those.

Then there are the confusing parts of the conversion:

When someone who knows diesel looks at your engine they don't know what motor it is.

What do I do with these fueling and timing boxes I bought?

It sure sounds like a 12V!

Is that a tachometer or a boost gauge?

You constantly say to your wife, that is light throttle!

You say to others, if it smokes that bad don't follow so closely. Then you coast it when you go by the police.

You're always asking the the 12V guys, Are you sure there's not any 24V sled pullers?

Do I read the 12V or the 24V forum?

Its kind of like being a half breed in the old west, you're hated by the White man and the Indian.

Sounds like it does have it's negitive effects! :-laf



I have heard of Schieds doing the conversion, but if I had the money and he was willing to, Piers would be my man no doubt. However, this was just to get my mind off that damn transmission thread.



thanks for the input Mr. cabrokr, i know you've been there.

I can relate, Andrew we need to go for another ride, it spools stupid now, nope same pump same turbo's!

Why, so i can have more p-pump envy?



Well it obviously looks like there will be no part listing huh.

I really don't have and can't make a list of parts. And as you know its not your everyday request for most shops. I would say that if someone is serious to inquire from a shop well aquainted with the 12V. Piers is the man.

I agree completly David, I was just wondering how many parts we(TDR) could come up with. I have seen more on other threads, but I guess they are busy arguing about trannys, not me, my DTT is on the way.



Thought this would be an intresting topic, guess not.
