I’m going to start the chant I hear in the back of my head.  It goes something like this:  Dur-a-burb.....Dur-a-burb..... Dur-a-burb.....Dur-a-burb...... Dur-a-burb.....Dur-a-burb........DURABURB!!!!!!!!

I’m not a nice guy at times.

This is where it needs to go.... but only after he gets home from this first trip. Even if he wrote a check, I don’t think they could get a duramax in it in time for June trip.

Duraburb for the win!

Its a fun truck as it is, but that duraburb went by me like it was idling.

I think I probably should take the leap to diesel it out with a nice ally

But after the trip

And now I need to start the process of talking myself out of doing it!

The burb still has some strange problems, so I am running them down one by one

The right rear door: No speaker, no electric window control

Pulled the panel and found both the switch and the speaker partially unplugged. Wires reattached and everything works fine now

The stereo just wasn't sounding right. So I tuned it in several areas. The amp, the sub woofer, and the equalizer and I would say it now sounds great

The underhood lamp ground wire broke off, so I repaired that

The winch hot lead, attached to a 100 amp mega fuse was not getting voltage and the winch was not working. SO I reattached the lead to the local hot battery post and that unit now works again.

The overhead lights quit working. I have not figured that out yet.

I have brake fluid accumulating on the drivers floor mat. It's not the master cylinder abt seems to be coming from those new -4 brake hoses I incorporated into the parking brake system. I tightened the fittings which were all tight already, so the jury is still out on that one

The six rib belt powering everything that spins on the front of the motor turned itself into a 4-rib belt. I removed it, and ordered two new ones, due in Thursday.

I had two additional sets of lights to wire in to finish that out, so I got started on the top push-bar lamps which will be triggered through a relay from the high beam

Then I finally installed lights powered by the factory fog light circuit and harness. I will use these for side illumination at night.

That installation is complete now and works fine

I am still having a battery drain issue, but other than that, it's down to solving the leaky brake line, installing a good accessory drive belt, amd sorting the overhead lamp issue. After those few punch out items the burb will be ready to travel. I'd make it 98% complete/ready to go at this point.

Funny, you built a wood water tank for the trailer and it leaks someplace.

You built a wood base power system for the burb and issues are showing up.

Actually cept for the drain issue, seems simple.

My burbs batteries showed 100% on one charger and DOA on another. Been cycling and trickle charging em and seems they are doing OK now (little low on water too) Showing 12.4 normally and holding high 11's under a load check. Few more days to tell is I need new batteries

Maybe some woodtrons got mixed in with the electrons, then some termites went in and disrupted things...Could happen...

Battery is up to 13.something and acting normally. Been on and off trickle charging it for daze now

I looked at that and everything looks normal. in alignment. I spun the motor up once, the first time just before I noticed it. I really don't know, but maybe all the wrenching and fitting around that belt could have cut it in some way...(reaching here), who knows. Nick did say that sometimes these superchargers will toss a belt and he suggested I carry a spare. I ordered two which will come in today. And I will likely not spin the motor up again, just no need to do so with a heavy burb.

I just continue to run down the little issues this truck is having.

It developed a problem with the fan circuit breakers popping that I just couldn't sort.

You would be sitting in traffic and the temp just start to creep up. Open the hood, and push in the breakers and the fans would kick in lowering the temp.

I suspected the unit was not grounded properly, and I was right. The fans normally ground to the alternator bracket, but that went away with the supercharger installation. I found everything grounded to the battery tray hold down. I made up a ground cable and attached that to the alternator bracket and while I was doing that, I was running the engine and fans and when they kicked on from low to high I thought I saw a spark near the relay stack.

Upon investigation, I actually found some wires were not making good contact INSIDE A STEEL CRIMP!!!!!

Yep, never saw that before either. So I heated and soldered that connection and remounted everything and so far fans are running strong like they should.

I found that inverter which was bad, and I found some mega fuses which don't seem to be burned but are not working!!!. I replaced them and simplified the wiring and now everything electrical is working.

Finally and it is the last thing, I traced down the brake line leak. Again, I have never seen this before but one of the new teflon/stainless steel hoses is bad. No leak or evidence of any wetness at either end at the fittings, but the middle of the line is wet!
All those years flying hooks which are two big rotor systems tied together by a net of hydraulic lines and I've almost never seen a line fail or leak in the middle somewhere, other than those which were grazed by some high speed projectile.

I'll replace that line and that should bring this truck to 100%. And it is running really well. Loads of torque and accelerates at part throttle effortlessly. We should be hooking it to the trailer for a test run in just days.

Nick and Preston did good, proud of them.
John the transmission guy did too, good people.
I finished the brake line and running down things and have nothing to fix, the burb is 100%
I've been driving it
Only real complaint(s) is the high cruise RPM resulting in poor mileage.

So, I'm tweaking the setup some more. Before I do something drastic I'm going to install larger tires to slightly lower the RPM. I just ordered 5 new Kanati Trail Hogs which I have been wanting to try out. I'm in to these supposedly cheap tires, which from my growing experience are just as good as tires costing much more. I obtained these Trail Hogs for $239 ea which is just killer.

I'll remove the 35" Dick Cepek tires and call it good. THis will lower the RPM about 125-150 depending on the actual outside diameter.

Looking further down the road, I am contemplating a big inch stroker bottom end with a torque cam. I am seeing 500 ft lbs to the ground and although it has no problem moving out quite smartly, it is not diesel like. A diesel conversion is going to get into the couple of ten thousand range, and like RedNeck points out, I would be further along to just buy a used duraburb, which I might well do and just add to my collection.

Anyway, tires first and a bit of tuning to see how this all pans out.

Funny, I am thinking about staying with my 35 tires on my Dmax. I love the way it runs with the 4.56 gears and the 35s. Decent mileage and I am pulling hills all time and towing. I only see 2k rpm at 70mph.

I need to try cheap too, $300 each for the Coopers right now, need to find a sale.

Some thoughts on the repower.

As we have discussed in the other thread, I am looking to repower the burb.

Reason? Well, even is supercharged form, I do not think it is all that spunky, at least not like my much heavier diesel truck.

I have looked at going to a big inch LS short block. I have looked into a Cummins 12 valve. I just got done researching the Chevy 8.1L, 496" motor. I have even looked at stroked versions of the latter reaching 572 cu in!

There seems to be problems with any of the above. The LS motors, no matter how big have to be sun up to build big numbers, and those big numbers only get to a low powered D-Max.

The big block would require a 1,000 gallon tank to have a 500 mile cruising range. Even though it could be built to generate 900 ft lbs at a low RPM, it would never see double digit MPG, so the practicality of that is questionable.

That leaves me with the 12 Valve, A duramax, or leave it alone and live with it.

At the moment, I am awaiting a Flex-a-lite fan to keep the thing cool and have 37" tires sitting here to cut back the RPM some, so it is static until those get installed. The gasser with the 4L80E with its puny .75 overdrive will always have me turning mid 2,000's while cruising so that, too, is a limiting factor.

The 12 valve could be made to work and would be dirt floor simple, but mating that to a transmission that would fit and give me a decent OD while playing with only 360 cu in presents its own set of compromises.

Now stellar warp drive and helium 3 fusion drives have not yet been invented so that leaves only:

1. Leave it alone
or
2. Swap to a duramax.

Now many of you have suggested I just buy another duraburb and be done with it. But would I?

Every duraburb I have looked like were only part of the way there to what I want. THe most recent LMM powered 2007 had this awful pro-comp lift kit which hangs the torsion bars down for everything to catch on. Then gaudy 20's, and so forth.

My old 2002 has been nearly completely gone through. TO do that again would be another 6 months plus and I am just done with the major rebuilds for now.
I just want to use my old burb and get it to act like my truck

Therefore the only thing that makes sense, after all things considered is to swap to a Duramax.

So, I have written D-Max swap to get a line on the conversion harness.

I have located a donor LB7 powertrain to start with. Engine and five speed ally for $1500 and its running.

if I decide to go through with this I will rebuild and strengthen the LB7 bottom end. I'll add LLY heads and top end. The five speed ally will get the treatment and be converted into a 6-speed.

I will lower the lift by 2" and then install a 2" body lift to make room for the Allison trans.

After all that and I have a working engine/trans, I'll bring it all together using mostly stock parts.

The plan will be for a 600-700 HP motor with the 5 position tune switch. The trans will be built to handle all that and thereafter, nothing will remain to be done!

Remember last week when you were talking about excess stuff, and time?

Send the burb off and write the check. Save you the time, use it where it’s more valuable.

Remember last week when you were talking about excess stuff, and time?

Send the burb off and write the check. Save you the time, use it where it’s more valuable.
1- The check is obscenely large
2- That's just for the stock conversion
3- I really don't trust the work of too many folks
4- For the 20K I spend on labor, imagine what kind of motor and trans I can piece together
5- I won't learn anything if someone else does it

All valid points, but even at 20k, you’ll still be well ahead of a new burb. And recoup a little on the sale of the existing guzzler that’s in there.

I understand your need to do it yourself, just not sure if another 6 months of work is worth it. I know I wish I could have written a check many times, simply because of lost time.

Shop in Florida has been doing it for a while I’d like to think they are trustworthy. Maybe find a shop that has a warranty on the work?

I’ll also add, 3 months of mon-fri 8 hours a day, 50$ an hour (I figure your time is with that, and you skill), 24000.

Ok I’m done. And will enjoy watching this transformation as a Burbamax is something her and I have always thought would be a very practical rig.

Hmm, to much logic on both sides.

It is SO much more than just a motor/trans swap.

The style of lift is a shopping point, about the easiest thing to change too.

And to JR's point, he is so right in saying it will be a daunting task

But thinking about it, doing this swap is really in keeping with my whole life. I have never sought the easy path but rather straining to reach something I thought was unreachable. And I'm not trying to say anything to my credit, not at all, but I seem always to gravitate toward the difficult stuff. I don't know, some psychological quirk??

But, that's really it. Going from a gasser to a diesel will test me to the limits of my patience and ability. But it will also produce an inner satisfaction that cannot be equaled by "writing the check" so to speak. Making it into the NightStalkers was not easy. Staying there was not easy. All the training, new equipment, new maneuvers and then the missions. Crazy stuff that the Army looked on rather dimly. I thought that was silly of the regular Army folks to think of us that way, but it is clear to me now. They were jealous of a few men who could and did do things they could not do.

So all that is to say, a man is cut from a certain bolt of cloth. My people jump into the raging river, believing in their abilities and hoping with a certain degree of luck that they make it out to the other end. Because, you know what happens in between the jump and the end point? LIFE happens, and experiences that few will dare and almost none will experience. As crazy as that sounds, the lure of trying to get this D-Max suburban conversion myself is just too much to avoid.

It starts tomorrow.

Sweet, a hot rod duramax build. "fluid change" on steroids!

Funny, I keep bouncing around with the sub on motor work. Need it to run good for now but that 6bt is sitting there to. Not like I have anything else going.

Are you going to rebuild the tranny or just get built unit?

OK, time for another update
and
discussion

So I was off and runnin' trying to find all the parts to convert the suburban into a duraburb thing. That was going well. I had located a donor LB7 and allison for $1500 which was worn out, not running, but rebuildable.

Then I had to go and get heart surgery

That turned out fine, but after I sat in front of the monitor and TV screen the required 5 days, I got busy about going to fetch the donor parts

Well, the guy sold it all in the past few days and I am left with nothing

That caused me some pause and time for reflection.

A quick check of FB marketplace and there are plenty of donors at 2X-3X the cost and mostly 400 miles away...hmmm

Then I started to look at the cost of this

Cores/harness/front cooler clip: $3K
Rebuild Ally: $5K
conversion to 6 speed: $1.5K
LB7 injectors $1,700
LB7 Pistons: $1,700
Rebuild kit: $500
Machine work: $1,500
Heads $1,800
Rework driveshafts: $1,000
ECM/TCM HP tuners stuff plus new harness $1500
New radiator/IC $800
fluid damper, studs, things $2,000
Transfer case $1,000 at least
instrument cluster and assundry things: Who knows
Camshaft $1000
Lifters: $800
Turbo: $2,000
Exhaust, down pipe, AC lines redo...$$$
and on and on and on.

Looking at it in the aggregate, WTH was I thinkin'???

I'd be $20K plus deep into this thing without a second thought and maybe more. I'd have everything I needed and more, but is it really worth it?

I started this thing because I really wanted to lower the cruise RPM and the 6 speed ALLY which needs a duramax to shove it around is an add-on. Since I'm putting in an Ally, might as well do it right, Right?

So with a long exhale, I said to myself, "Don forget this crazee idea you bonehead!" Have to admit I am surprised I spoke to myself disrespectfully, but, hey, it's me, OK?

So he sez, Don, why don't you just drop in a 6L90E? Has a .67 top gear would lower RPM a good deal, sure enough
I added up the costs and when the figures started to eclipse the $8,000 mark, I had to question meself once again.

So I calls me transmission guru, John over at SS transmissions in the Alexandria of Kentuckee. He sez, what the heck you thinkin? He literally says, Hey, I've never done a swap like that, mostly because it doesn't make much sense, but if you want to spend the money, I'd love to experiment on your suburban. John is a good one. He will always tell you the truth even if it is costing him money. He's just honest and since he has to go to bed and wake up ever night with himself, he wants to like the guy behind the morning shave.

Then I did some calculatin' excuse me, for you rednecks, good ole boyz, and numbskulls, I did some cipherin'!

Check this out:

Stock 2002 Suburban 2500
4.10 gears, .75 OD ratio and stock tire, 265/70, 31.6" tall   75MPH = 2452RPM
Mine:
4.88 gears .75 OD ratio 37" tires                                       75MPH = 2493 RPM

So this setup moves up the revs, a measly 41 RPM, like as in less than half a hundred

So, its a big burly 3.4 ton truck. It is meant to be spinnin' up whilst truckin down the highways and byways.
I'm gonna live with it.
Yea sure, I think I'll get John to rebuild the 4L80E and add in a good converter and call it a day with all that
I think I'll bolt in another 40 gallon gas tank to increase my range to over 100 miles
And I think I'll have a little fun and build a stroker short block and go for like 800+ ft lbs of planet destroyin torque.

Yessir, That's what I think I'm gonna do...

Now theres an idea that doesn't break the bank. Not cheap, but doable.

Now, what about the overheating issue?
