i might hav the opertunity to buy a injector pump off a 2001 dodge 2500. can i make it work on my 92 d350? would it be worth it?

jimbo486

doesn't seem possible. even though the VP44 is a rotary/distributor type injection pump, it's electronically controlled. but, if you're an electrical guru, give it a try. in my opinion, it might be more work and effort than it's actually worth. you'd be better of throwing a p-pump on it. in comparison, you'd probably spend less on the p-pump swap than you would trying to make the VP44 work.

You'd be better off going for a P-pump. You would need the ECM from the '01 to control the VP44 and even if you did get it all working, the track record of the VP44 isn't that stellar which is why you have VP44 guys going back to the P-pump.

oh ok thanks guys. i might hav the opertunity to buy the turbo off of this truck also. would it be better than goin with and 16cm or 12cm housing?

jimbo486

depends on what your ultimate goals are for the truck. if the turbo on your '92 is stock, either of those will be a huge upgrade compared to the 21cm housing aka the lagmaster.

Is the '01 a stick or auto? The newer auto's had the HY35 with a 9cm housing. Not that it is all bad, but something to be aware of. If it is a stick it would have a HX35 w/12cm. This is provided it has not been previously swpped out.

The 24v has a different wastegate actuator, too.

it is and automatic

This is kind of OT, but kind of on topic.... has anyone ever put a (98.5-02) 24V head on a first gen engine and still utilized the VE pump?

Just curious. Seems like it might be a waste of time unless you had to get your truck running and had a busted 24V engine to pull the head from.

JustRamIt91

and i'm sure there would be other problems to consider as well.

jimbo486

i'm sure it could be done. given that the head is fully assembled with valve bridges and what not, the only things i can think of that would be needed are the exhaust manifold and custom fuel lines. the cold-side intake tube would probably need minor modifications. spray angle of the injectors might be a little off but if someone was really into it, they could have nozzles with the right angle put into the bodies.

CaptainChrysler

You would have to use 24v pistons and injectors. The 24v has lower rocker arm ratios, so you would want to change the cam to make up for it. You would have to adapt the VP lines or get custom ones. The VP uses 14mm DV threads.

It has been done. We threw the idea around, bench racin' ya know.

The reason why nobody has done this (the VP44) is the same reason why hardly anyone (only 1 that I know of) puts a Powerstroke into a Dodge.

EDIT: I want to find a 24v VP44 truck with no pump and put the VE on it. That takes care of everything!

Well said!

Cummins has the lines for a VP to 12 valve engine. Use CPL # 8300. That CPL is for a 12 valve with a VP44 injection pump on it.

For a PCM you would need the cummins PCM used for that combo.

In a stock 12 valve engine the VP based engine pulls better than a p-pump engine does.

CaptainChrysler

He was talking about using the 24v head.
