Engine/Transmission (1994 - 1998) Industrial P7100 questions?

[roachcoach]

Hey guys, I've got a 92 VE. I've also got a 230hp P-pumped Cummins out of a bus. I'm going to put that P-pump in my 92. First though, I'm going to do all the mods I can while the engine is out of the truck. I've got a general idea of how to get to 500-550hp. I've got an Industrial Injection Phat-shaft 64 with a 14cm exhaust housing, I think that'll support 550 horsies well enough. I know that I'll end up needing a lift pump system, whether it be FASS, Air-Dog, or any other reputable electric lift pump producer. I also know that I'll need some sticks, I read that a 7x. 012 would be relatively good, then somebody mentioned that a 5 hole injector is the better way to go. I'm going to get a 3-piece manifold, not that that's going to help me achive my 550 goal, I'm just doing it. While the engine is out I'm also going to have the head o-ringed, maybe a little porting also, and get some ARP's. I think I've got a pretty good foundation of parts here.



Now to the pump. From what people are saying, this is only an 11mm pump, because it's an industrial application I'd guess. I know I can do all the work myself and get enough fuel out of it to reach my goal. So, please, give me some advice on what parts I need to get to get the fuel comin' out of this thing. Can I just do a gov. spring, fuel plate, delivery valves, and tune the AFC or would I need more?



Thanks,



Craig



Alright guys, I've got a few more questions now. I've run into an odd situation.



Question: What size is the threaded part on the top of the injector where the line connects on a 12v p-pump engine?



Odd situation (I think): The injectors on this engine have a 14mm connection on the top of the injector. My VE and the p-pump in our D41 komatsu have a, I believe, 12mm connection. Also, the female part of the connection on the line itself is a 19mm(wrench), compared to a 17mm(wrench) on my VE and the p-pump in our D41. Is this thing just odd or what?



I also took some pictures of the progress I've made in the last few days. I'm not killin' myself working on this thing, I'm just taking my time and trying to do a nice neat job.



Day 1, I got the pump off (I didn't get any pictures with the pump off though for some reason) and got all the industrial type junk removed (air compressor, huge alternator, and a bunch of junk on the front of the engine).

I went four wheeler riding yesterday so I didn't get anything accomplished.



Day 2, I got the head off and some other odds and ends removed:

Sounds like a good plan and you are off to a good start.



What I found on my '96 is that the injector threads were 14mm x 1. 5.



As far as the p-pump I am not much good since I am still learning my own.



Your pictures make me want to tear down my core block and start building again, then I remember I need a better reason than that since I would either end up dead or divorced. :-{}

Okay, I'm extremely happy to hear that the threads on our injectors are the same. I was worried I'd have to get new injector lines and I know those are not cheap.

Thanks for the help, I think I'm going to take the barrels out of my pump and mic the plungers to see exactly what size they are. If they are 11mm like people have said they are I'm going to take the pump to a shop and try to exchange this pump for a 12 or 13mm pump. If it's already a 12 I'll just build it up a bit.

 

[roachcoach]

It is indeed a 12mm pump, I put some vernier calipers inside the barrel and it measured out 12. 014 mm. I found that it had no fuel plate though, which discouraged me a bit.

Also, how far should the arm thingy in the AFC move back and forth? Mine wouldn't move at all. Here's the arm thingy I'm talking about.

Got the oil pan off of the block this evening and wire brushed it. I'm going to get some engine enamel and other things tomorrow so hopefully by the end of Friday anyway I'll have it cleaned up and painted. I am in the process of finding someone to o-ring my head. I have to order injectors, gov. springs, delivery valves, I think I'm going to get a fuel plate of some sort, 60lb valve springs, that should be the extent of my parts list so far.

Also, for somebody that may know, will the stock lift pump supply enough fuel to hold 500hp?
