96 P-7100 pump & turbo onto a 93

[Jim Curry]

Hey guys;

Here's a question for you. I may have the oppertunity to pick up a p-7100 pump off of a 96 engine. If I get the pump and all of the front end parts off of the 96, is there any other parts I will need to install this pump on my 93? Furthermore, if I do get the p7100 in the truck is the best injector still going to be the lucus or will the 370 diamond b injectors fit the 93 but have not been used because of pump limitations.

Then there is the question of the hx-35 turbo and 12cm housing verses stock 93 turbo with 16 cm housing?



Any info and feed-back will be appreciated.



Jim

Jim,



Consider keeping the 215 injectors you've already got & just putting in a bigger fuel plate. The 96 & 97 215hp pump has tons of bandwidth in the fueling arena.



The fuel plate is only $300 & tons easier to install & you can probably get all the fuel you want. Consider going straight to the #8 in the centered position & try it out. The 16cm housing will handle extra fuel ... hold on!

Jim,



You will need a lot of parts off the '96 and it's a big job to change. I've heard of it being done but have no details. I do think you have to change the gear case which ain't easy since the cam shaft has to come out to do that. You will need a timing kit to install the pump correctly. I think SnapOn carries them. If not Miller has them at: http://www.spxmiller.com/ A '96 Dodge service manual or a Cummins manual would be a big help.

Either the Lucas or the 370s will make good power but the former has the small threads and won't fit the P pump's lines. You will need the lines, injectors to fit them, oil feed T and lines to the injection and vacuum pumps, gear housing for the P pump, pump gear, pump mount brackets, fuel inlet lines/filter housing as required to match up, probably the 94 up air intake to clear the injection lines. The early intercooler and pipes are smaller than that used 94-up, so use the later stuff if you can fit it to the early chassis--the intercooler will probably be a bear to fit.

This is not a weekend bolt-on project!

Just keeping thios current so it does not get lost in the sauce.

I'm with Joe on this one. A couple guys wanted to do the job and once they got an estimate, they just went out and got the newer truck instead.

It seems as though switching from either of the rotary pumps to the P pump requires a gear housing change. Anybody know if you could swap the VE and VP-44 pumps? Not that I'm thinking of doing this (yet) but the computer controlled pump doesn't have the tuning (mileage) capabilities of either of the mechanical pumps.

The VE and VP44 use different bolt patterns, etc. Not a bolt on, sorry. Moreover, the VE was used in Original Equipment applications for up to 200 hp only (6 cylinder versions) and we know the VP44 will flow a lot more fuel, especially when "enhanced".
