24v transplant!

[hickracetruck]

Hey guys, I have a 1990 cummins with getrag. and my motor has 650k on it and do not want to touch much to make power with it since its higher mileage. and i have found a 2002 24v HO 245hp motor out of a 6spd manual. It is without the injection pump with 211k on it so i figure i can get it cheap. But i am wondering how hard it will be to put in my truck. I will be p-pumping it, which is an easier choice for power down the road. Do they use the same wiring for sensors and everything? Just wondering how many big problems i will run into with the swap, and i plan on finding an nv4500 or 5600 to put behind it when i do the swap. Any help at all will be greatly appreciated! Thanks so much! and this is the truck its going into after its built up. dont mind the rust, it will be gone very soon, Thanks for any help!

I would just find a P-Pump 12 valve. Finding a whole truck would be cheaper then piecing it together.

comp-d has a whole section dedicated to p-pump 24v cummins'.... might want to check it out

well i found a complete motor with all wiring and everything for like 1250 with no injection pump so its perfect for what i want. and i would have to peice the parts for the p-pump together anyway, and i know guys who can get parts from junk yards. and i want more of a challenge. since im 16 it will be a good accomplishment

what is your end goal for this truck ?

it maybe cheeper to inatall a P=pump onto that old valve keeging the getrag

heck if your only looking for 400HP the older VE pump you have will do that with the rite tweeks and TLC

[hickracetruck]

my goal is the most streetable power possible without giving up reliability and mileage. this motor is to worn to be trustworthy. keeping it stock will let it live forever, adding 300hp will only let it live on borrowed time so long. But thanks for the input

i have seen that truck, and its fast and everything but i have found a very cheap 24v without the i/p but everything else to drop it in. just find the parts for the p-pump and let er eat. all i wanted to know is if i could swap it into my 1st gen without many problems, mostly from sensors and connectors.

To me it seems like you're going in the wrong direction. Going from an ALL mechanical engine to an all electrical engine. I wouldn't worry a bit about your high mileage. Put that $1200 into your engine. My twin motor had near that many miles before I starting 'bombing'. Along the way it received a new style head (wasn't anything wrong with the old 9mm head/just was told how 'bad' they were way back when ), new injectors and turbo(s). The rest of the engine is high mileage and it still runs great.

Find a 1994-98 5 speed and rip out the engine/transmission. Sell the rest, axles alone would fetch you $1000. Judging by the rust on your frame the old body is shot.

Is that true or a rumour?

$1200 for the engine $1000 for p-pump parts equals $2200. There are p-pump engines going for $1500 on toronto kijiji.

i dont have the money to buy a complete other truck that has lower mileage and it has to be 4x4 . and the body is shot, but i got 2 parts trucks with different good body parts for scrap price so im set in that department. if i had 5g to spend on a p-pump 12v with nv4500 and 4x4 i would have gotten one in the first place. and put a first gen body over it.

To answer your question to the best of my knowledge by putting the p pump on the 24v you will pretty much be eliminating any of the electrical nightmare, along with a standard tranny. I'm not sure on the motor mounts for it. From what I've been told it is usually cheaper to find a whole ppumped 12v to get all the parts you need for the swap. I think you will also need a set of aftermarket injection lines to run it on the 24v. I actually think it would be a sweet set up if you have the cash to complete it. But if it was me and I had a motor out of a truck with the mileage on it and I was wanting to build it to eventually someday hold some high hp, I'd rebuild it and go through the whole thing before wasting my time putting it in a truck. I kick myself for not going through mine, and now I plan on pulling it this winter.

My suggestion seeing as to how you said you are 16 and can't afford a newer truck is this. Before you start spending any money is very realistically price everything out. I can tell you from restoring my 90 that it is the little things that you don't think about that end up costing a lot of money.

You sound a lot like me, but something hit me smack dab in the face over the weekend.
While I may have a shtiload of good parts and engines, it doesn't make a good tinker's damn, 100 miles away and dead in the water.
When I'm out on the side of the road, with a tranny ready to let go, and I don't have 2 nickels to rub together because I spent it on some BS I "THOUGHT" I needed, then I couldn't afford the tow truck I may have needed.
It tends to make a person wake up and decide about the priorities they keep missing right there in front of them.

I'm tired of mucking with everyones else's leftover, used up junk that noone else will buy.
It's time for something REALLY GOOD.
Let's just say there's going to be a lot of "EXCESSIVE" stuff LEAVING by any means necessary.
If not on this and other "Enthusiast" forums, then on Ebay.
But I digress, more on your topic.

You already have a running, but very high miles engine.
You want to buy an engine with no injection pump that'll cost more than double what you can both build, AND modify, your current engine for.
In reality, there is a better than even chance that all you'd have to do to your '90 engine is de-glaze the cylinders, install new guides in the heads, a good 3-angle valve job, polish orr re-cut the crank, new rings, bearings, gaskets, turbo re-build (good time to upgrade), re-seal the pump (Also a good time for the 3200 GSK & mods), change to hotter injectors, upgrade the lift pump, etc.
Then you'd basically have a NEW engine with some noticeable horsepower gain.

Figure a basic rebuild on a VE engine, then figure the extra cost of the "performance" parts you would want for it.
Now figure the initial cost of the 24 valve, plus the cost to rebuild (you should rebuild), plus the additional cost of the special injection lines, the P-pump conversion, add in a bunch of agravation and headaches of sorting out a "unique" combination that presents it's own set of rules, variables and issues, which few people understand, much less share information about.

i have a 2002 24 valve , 4x4 , auto .
if it was a manual tranny i would have replaced the vp 44 with a ve pump .
it is a much easier and cheaper swap than going to a p pump .

hey-Hey!!!,
saw this one:
http://washingtondc.craigslist.org/nva/ ... 74347.html

it is a complete, low miles P-pumped 12V with a gearbox you could sell. Also has a big IC along with it.
cheers,
Douglas
