A p-pump conversion is around 12K. You can bolt the parts on for cheaper but making it all work in harmony is the key. Trust me there is a lot more to it than just removing the vp-44 and bolting on a p-pump and that doesn't even cover the tuning issue once its all together.

but that is the only place i have seen that can take the money. travis will be doing all the work and the tuning. unless there is some 8k dollar magical bolt i can't see where it would cost near those figures. and how hard would it really be to tune it in. he can set timing and check pressures. i advised him not to put in a 4k kit till it is tuned in right.

Didn't you read Jetpilot's post and sig? I think he know's what he's talking about. I'm sure he could inlighten you as to how light his wallet is now that he's P-pumped and to how much trouble the tuning issues can be.

Don't get me wrong I think it's cool as heck but I also don't think you're going to do it for under $8k in my life time.

Good Luck though.

obviously the 98 24valves are more prone to losing the VP44's, but don't you get the "newer" versions when installed after losing one? a guy from the tdr is on his 4th pump in a 98 24valve. dunno..

i know i can bolt on a p pump to the motor and hook every thing up for under 1500. and i am counting a new frount timing cover, 215 hp pump and a set of lines from one of the shops. so where is the other 10,500 bucks in stuff? i heard that geting the timing right can be a pain with the pop off pressures being different. but i think he will be able to figure the timing out without to much trouble.

Dr. Evil

Im not saying you cant do this for under $1500 - but wouldnt there be a lot of guys doing that if it were that cheap???

gunracer1

heck it sounds like people talking about building twin turbos acouple years ago. everyone said it couldn't be done, now it is done all the time for cheap.

well i'm going with this , one question for jet pilot .. did he do all the work himself , also scheid does not change the injectors they say there fine , tons of people get rid of there mech lift pumps on 12 valves so no cam work , electronics ive learned are simple as pie , ive got the pump , ive got the case , ive got the lines ,and pile of misc parts , and ive got less than 600 $ in this thourgh swaping and selling my boxes ... ill repost later and tell if this is a disaster or a success thanks everyone for the info , travis

Travis:

You can contact Mike Wood @ Scheid Diesel about the
P-7100 pump conversion. He is driving a truck that they
did it on and he should be able to help you. His phone
number is: 1-800-669-1934.

Also, Doug Smith (Jetpilot) recently had his 24V changed
over from the VP-44 to the P7100 pump. Piers did all of
his work for him and I believe he is very happy with the
conversion.

The P-pump actually runs at higher pressure (16,500psi) than the VP-44 (14,700psi).

rick at scheid said that you DO NOT have to change injectors , he recomended 275's or larger though... thats what i've got , anyway no matter what the popoff, it would affect the timing ...i can time it any way i want

Jetpilot

The p-pump conversion is not foe the faint of heart. Another member did his own and is not happy with the results. I am not saying that none of you can make it work, just that there is a lot more to it than just bolting on some parts.

There are LOTS of little things that go into making it work....... The lift pump issue is not a real problem, you can run a high pressure high volume pump and set it up for around 40 psi to feed the p-pump. The injectors do not have to be changed, but trust me the truck likes it when the injectors match the setup. I learned this personally!

There is headwork to be done so that you can get to components that you will want access to. Also the timing cover needs to be machined for the setup.

As mentioned prior PDR did my conversion. I love it and it runs awsome! But mine is setup to make max HP not for everyday towing etc.

Good luck,

Doug

Think that biggest issues for this swap is where are you gonna get the injector lines that go from the injection pump to the injectors. Who make these one of a kinda lines? Alot of stuff runs off and thru the VP-44 pump. I was told that your dash wont work and your cruise is useless. The best way around that was to leave the VP44 pump installed but off to the side. Ya you get it put together but is it really worth it. I was told $10k and you have to make your own injector lines. Buy a trick VP44 pump and a Fass fuel pump. It will be your last injection pump for 1/3 the price.
