Bye 300HP 6.5

[DogDiesel]

Will have it pulled today.
Have a 1997 12V 5.9L Cummins uprated to 300HP all adapted to drop in.

The fun begins.

...another one bites the dust...

Just kidding! Good luck with your new project, and keep us updated on how it goes.

[DogDiesel]

... the 6.5TDA is pulled.

Shopping to get bolts to attach the clutch to the new 5.9 GM flywheel. I'll set the 5.9L tomorrow. Other than clutch, it is ready to set.

My clutch kit is a LUK. They're right here in Charlotte, NC and I dropped by and got one - it was cheaper than the one I had behind the 6.5. Nice.

Had my (OEM Chrysler) Nippen Denso alternator "chipped" to become an internal regulated, complete with tachometer output. We put it on the tester, it rated 144 AMPS and 14.3V consistently. Neat. I have doodle diagrams to wire it up.

Once set tomorrow, I think the big challenge will be just plumbing the intercooler. Wait, let me set that big thang before I talk about intercooler. Wow, that thang is big. It dwarfs my 6.5, although the weights are similar.

Theoretically, it will fit. Tomorrow.

Have a 4" exhaust kit; hmmm- my 3.5" Banks PowerPack exhaust kit is up for sale. Have the K&N Cummins kit. So the 6.5 '93 K&N (complete with housing/plumbing), and intercooler kit will become available soon, as well a butt-load of other 6.5 uprate stuff.

I'm taking a few pictures.

More later.

Keep us posted on the total cost of your conversion.

This is something I have dreamed about for a long time........ Do you want to do another? For me.

[javadog]

I want to get in line behind Mark.

[DogDiesel]

Tempting.
I'm using the Auto Crafts shop on Fort Bragg. While I have a cherry picker that will pick up the engines, I do not have a cement pad in the back yard to use. I considered buying a couple sheets of steel and using that, but after 25 years in the military, my death wish is on low priority.
If you can get on a military post, we can work something out.

Maybe I could lay a pad near my shop...

I think I enjoy fixing them more than driving em.

I'm on hold till Wednesday. The LUK clutch didn't feel right. I'm taking it back on Monday, and shop for another model. Gotta feel this thing out. I took the flywheel off, we'll get it right this time.

Cut the rivets on my drive shaft carrier cross member, and have everything ready to shift the transmission/transfer back 2" to allow for more room under the hood.

I bought my engine and mounts from a fellow named Robby at ADC engines in Salt Lake City. He gave me free shipping after he found I was calling from Iraq to make the deal. Seems like a real nice fellow. Vietnam Vet. The engine and set-up seems top notch. My unit has 58K.

Did I mention that the 5.9L just seems huge? yeah, I know, its like less than 50 lbs heavier than the 6.5, but geeze it looks huge. I think I am going to appreciate the extra room under the hood on each side.

If there is a line forming I am in.
Pictures and some kit info.
Does the kit make it a bolt in swap?

You may want to consider getting a South Bend HD clutch. Upgrading the power on the Cummins is so addictive that you'll soon run out of clutch holding power if you don't do it right the first time.

I'm going to install their 13" Con OFE to hold the 400HP/800ft/lb+ I'll be making with my 1994 12V 5.9L.

The goodies so far:

191 Delivery Valves
4K GSK
60lb valve springs
300HP 5 hole automotive injectors
PDR HX35W turbo set to 36psi
2nd gen. DC intercooler
NV4500 hybrid Chevy with Dodge input shaft

[DogDiesel]

Yeah,
We're constrained by choices on this clutch thing. NOT! I can change the input shaft on the NV4500 from GM 1 1/8" to Dodge 1 1/4". If not, I am limited to 12" clutch, which I will be satisfied and running the LUK gold series 12". If I change the input shaft, change the flywheel and go to 13' clutch plus put in the adapter to space the starter... that's way to too damn many expensive choices. My 12" stock clutch with a 300 HP 6.5 looked brand new at 44K use.

But I am really not bad on clutches. While I probably tow as much as any on this board, I get more than 100K per clutch, always.

Tech advice is often to tell others on tech forums to put in the expensive part, a sure fix to all problems. Sure,I use the truck. I tow. But will NEVER pull a sled, or compete in a trailer tow for free. No off-roading except on the farm. Won't and don't drag race, knows diesel is less competitive than gas. But I only drive Diesel. My lawnmower, that lowly yard implement uses gas....

I thought things thru and the 12" clutch will suit my need. Not a youth anymore.

Here's how simple it is to harvest RWHP from the CTD: Doubling HP

I can see now why there are so few 5.9 Cummins conversions in a Chevy 4x4.

Analogy. Same as fitting a size 12 foot in a size 10 shoe.

Almost have the 5.9L set. The Bragg auto crafts shop did not have a tilt-able engine sling, and this caused havoc. A must on the job. My work-around was a chain hoist and second cherry picker and two chains. And patience.

First; to even get this engine to go in the engine cavity-without removing the entire front front radiator body support, you have to remove the harmonic balancer and speed sensor off the 5.9. Did that - move on.

With 4WD trucks: getting the 5.9L oil pan to slip in past the front diff requires loosen the diff and push it forward max. The oil pan will not slip past the diff without this. I had already pushed the transmission/transfer back 2". (Final set will have the tranny/transfer back 2" and drill new crossmember holes.) You have to remove the rear drive shaft in initial install. Once marrying to tranny input spline, you re-install drive shaft to lock the input.

I'm in, past the diff now, have the tranny input in clutch spline. Lacking only rotating engine to allow tranny align pins to seat. Sounds much easier than done. Everything fits and, but mass and gravity of the 5.9L in the size 10 shoe cavity takes any notion of "man-handle" out of the install equation. I stopped last night, because to rotate the engine, will require a bottle jack and bellhousing to tranny bolts just about 5mm longer for set. Of course the crafts shop did not have a bottle jack. Must rotate engine weighted to hoist chain which in effect pushes against chain. The adapter is aluminum, and OEM bolts might stripp. Err on caution and just buy longer bolts for the install.

So here I am, 1/2" to tranny seat, a mere rotation and few bolts away. Only the align studs prevent total seat. Spent 4 hours in that position last night. Should finish set tonight.

This job is like wrestling (no fake though). It looks easier when watching and theorizing than when doing. Don't try this at home without proper training and facilities. Somebody could get hurt.

Seriously. Wow. What a job!

When I have the 5.9L in motor mounts, and truck back in movable condition, I am trailering it home to plumb and fit and wire. I could go broke paying these bay fees.

Which way round is your oil pan sump? Is your truck lifted? I didn't have to loosen the axle or remove the balancer during the pilot install to drop in the 5.9L CTD.

I have the rear sump configuration, so it's about the same position as the 6.2L.

I'm not using the original 1994-1998 motor mounts, but instead have installed purpose built mounts from AutoWorld in MT (great shop with excellent aftercare assistance). These make full use of the height in my engine bay and keep everything clear.

Finally have the engine transmission mated.
My pan is stock pan, rear sump.
However, I am installing in IFS 4x4, not solid axle.

I have the engine sitting in the mounts. The mounts are not bolted. Better to slide.

I put the entire weight of the engine on the truck and the IFS sits at the same height as the 6.5. Didn't think there was but about 50 lbs difference in weight.

I only have to slide the entire engine/tranny/transfer back 1.5" now and set onto mount holes.

I was told I would not have to cut my drive shaft, but she don't want to slide any further back...

I will disconnect drive shaft - SLIDE- bolt mounts, and figure the shaft thing out. I may even have to trim the cab to allow the tranny shifter tower not to rub.

My goal is to finish today and trailer her home for plumbing.

BTW--there is so much more side room in the engine compartment. I can get to those frame mounted steering arms now easy. It was a killer to change them before.

IFS is definitely more challenging .

The 5.9L Cummins is in. Out of the shop. Ready for plumbing work.
--Had to notch front bottom bolt area of AC pump.
--Also had to modify right motor mount, to raise R/S engine to accomodate AC. Without AC, mount would have been OK.
--Trimed the bottom of left motor mount, as well right to allow space for pan bolts.
--Also will have to shorten drive shaft. Need less than an inch. The shaft into the transfer has 1 1/8" sticking out, but will not go in further.

I'm tired. Came home, got in the jaccuzzi tub and soaked for well over an hour. What a job!

I can see why so few of these conversions are done.
