Here are some of the early pics. Putting an '06 Cummins 5.9l in using Destroked parts. Just got the wiring harness and computer back from them so I'm guessing another two or three weeks until its finished.

 

I'm jealous. I'm going to start resealing my 97 12V this winter and start buying up parts for conversion.

That's gonna be a nice swap! It's unfortunate the powerstrokes are heui instead of common rail

 

08+ 6.4 and 6.7 is common rail...

Sent from my mind thanks to the Internet and an app.

 

I meant the excursions engines. I hate the new quiet diesels too.

 

I am sure it would be a nightmare to try and shove a 6.4l or 6.7l under the hood. Not just physically getting everything in but on the electrical end as well. Everything is more complex as compared to the 7.3l or 5.9l.

 

5.9L 12v 6BT is about as dead nuts simple and reliable as they get...

 

That they are. Such a simple yet effective motor. Looking forward to the progress.

 

With the V-10's being cable throttle's, would it be easier to put a Cummins in a V-10/gas powered Ex, or in a fly-by-wire PSD Ex?
Just trying to see if there is an advantage starting with a V-10 Ex over a PSD Ex...
Thanks!

Starting with a diesel is WAY easier. I believe gas engines use a different style of brake booster, gas engines create vacuum where diesel needs a vacuum pump to operate climate controls, no need to swap out entire fuel tanks and lines, intercooler brackets there already (modifications usually needed but easier than nothing) if it was a 6.0 it has a much stronger transmission, but the 4R100 is much easier to adapt to so it's a catch 22, diesels usually have a bigger cooling system (engine and tranny). Theres probably more but that's all I can think of now

 

I've have a 12 valve/NV4500 I swapped in to an 01 Ex, V10.

As far as which is better to start with, IMHO, I would start with a v10 over a diesel anytime. The purchase price alone will more than make up for any extra work or parts chasing. V10 Excursions can be had in great shape, much cheaper than a high milage, beat diesel.

The V10 and the diesel use the same radiator. The mounting tabs for an intercooler are also already there. I picked up an intercooler and pipes for $20 from pick a part. The Cummins will have a vaccum pump on it so you can just keep the normal vaccum boost brakes or pick up a hydroboost setup which I chose to do. Once again, $20 from salvage yard with one line.

The tank will need to be dropped and the fuel pump removed and replaced with some steel fuel line, along with the pressure check valve. You will also need to knock out the restrictor in the filler neck.

The diesels have a tps for throttle on the pedal and the V10 has a cable. Depending on what year Cummins, you wil probably need a cable type pedal the gassers have anyway. Just use the Cummins throttle cable and use a file to square up the round hole in the firewall and the Cummins cable will snap in like factory.

My personal recommendation would be to use the Dodge transmission and modify the crossmember if you have to. I made a simple mount to adapt the NV4500 to the 4R100 trans mount and crossmember that still mounts in the stock location.

If you have a diesel Ex already and want to swap, it makes sense to use what you have. If this is a project you want to do from scratch, find a nice V10 Ex. A running V10 motor will bring decent money when pulled or buy an Ex witha blown V10 for dirt cheap.

 

well i guess i overestimated how hard it was to overcome those issues!
is the nv4500 the auto or standard tranny? i know the autos are horrible in stock form.

 

Thanks Brutus! I have two V-10 Excursions right now, one here in Alaska, and one in WA state for when my family of 6 travels to visit family. When we move back to the lower 48, we will then have two Excursions. If the V-10 in WA dies, I would like to do a Cummins and a ZF-6. I also know of a Dead V-10 Ex here in Alaska for $1500. (Bad V-10) so that is one I'ld like to take on, but too many projects here right now anyway... Might get it for some needed parts, and then part it out... We'll see...

NV4500 is a manual transmission.

 

$1500 isn't bad at all. I paid about that for mine with a blown V10 and still got close to $1k for the drivetrain I pulled on Craigslist. If you have the space and the $$. I'd pick it up and just start on it slow when time allows.

I suggested the Dodge trans just because it is sometimes easier and cheaper to find a wrecked Cummins powered truck with everything you need vs trying to control the Ford trans after spending $$ on an adapter plate and $$ on upgrading it to handle the power the Cummins can make. If you have an upgraded trans already, by all means, use it but I personally wouldn't try to adapt a stock Ford trans to a Cummins. In stock form, either trans will need upgrades anyway so just build the Dodge trans and save the adapter plate and controller cash.

I prefer manual trans over autos so I chose the NV4500. Once again, if you have a ZF6, use it but unless you really want a ZF, I would use an NV and use the adapter plate $$ towards a good clutch. 6 gears over 5 would be nice but 1st is rarely used in either unless towing so it's really 5 gears vs 4 in a daily driver. If you have to buy either, it's a crap shoot on which you one you'll find cheaper. I do see probably 5 NVs for sale for every ZF6 so they are easier to find. A full NV rebuild kit including an upgraded, fully splined mainshaft, syncros and 5th gear fix can be had for $600 or so and you can rebuild it with only a bearing seperator. The NV has better aftermarket support and all kinds of upgrades and most weak points can be addressed. I know some people prefer the ZF to the NV for smoothness or gear ratios but for me, it made more sense. If you use a dual disc clutch, IMHO, either is going to loose some shifting qualities just from the mass of the clutch. The 3rd to 4th ratio drop is the biggest complaint I have with NV but with anything over stock power, it's not that bad.

ETA........ Sorry for the thread hijack. We can start a different thread here in the Ex forum or in the conversion forum but this thread is Scott's.
