Out of all the Cummins engine years, I found the 1996 year to be what I wanted. That year for the manual version of the truck had the most hp/tq, a little bit larger stock turbo over the auto, and had intercooling. Sometime during the late 96 year, the went from 12 valve to 24valve. Also for the fuel pump, it responds well to tweeking, and you can run wvo (waste veggy oil) or refined veggy oil through the pump with little to no worrys.
I chose the 12 valve. If you prefer, you can strip the engine of the wiring harness, then add only what you want.. the only problem you will run into is if you use an engine from a manual tranny, and hook that up with the auto tranny. you gain the 15-30 hp/tq with the manual.. but you loose the little device that reads your throttle positioner when using it with the auto. . Im told its easy to make one up. Anyways.. you only need a power wire to the starter and to the fuel injection pump. everything else is optional. oil, water, batt, charge indicators, tach, etc.
After that you have to decide on weather or not you want to go with the hydraulic tranny which uses no electronics, (47RH) ... or go with the other two options which are electronic, the 47RE and the 48RE. If you want to run the electronic trannys, for the extra gearing, and options they allow, you have to get yourself a seperate computer controlled valve body and a stand alone tranny computer. whcih you can program to do just about what ever you want. for an additional 1200 or so on top of the rebuild of the tranny which will be needed.
If you do the swap right the first time.. its not a cheep swap.. but I belive its worth the extra up front, than down the road when somethings gives out.
Id say.. about 2500-3000 for a rebuilt tranny with its stand alone computer, and a better tq converter. and up to 10K for all Billit parts. if your gonna be running over 400-500hp
.. Then you have to decide if you need to upgrade the rest of your drive train... Ohh and dont for get about the Killer Dowel Pin mod... Youll have to look it up for the excact details .. but if it lets go (the dowel pin) so does your engine.

ok so is the hydrolic tranny a standard or..? was there a standard transmission offered for these engines. also you mention better gearing in the electronic trannies, whats the gearing like compared to the standard tranny?
 
Do you know there are 17 pairs of volvo 303 axles with 4340 shafts and CVs, custom machined portal boxes, custom R&Ps and willwood 4 piston disc brakes, sitting in a box in south phoenix ready to sell?


....No... I didnt know that... How custom do the R&P get? Ill beable to get about a 2.1 or 2.3 R&P for the portal-teks, which will keep me at about 4.5:1 final drive. Id like to get the final to 4.10, With the Ft.Lbs the diesel puts out, Ill be fine with that ratio, and will beable to drive on the streets at 75mph. @ 2600-3000rpm.


As for the 47rh, H for Hydraulic, its a beefed up 727 3-speed transmission used for the cummins, I have a 727 tranny in my charger, but its different from the one they use for the Cummins.
It relies on hydraulic pressure to shift the gears rather than a computer. no computer, no headachs eh... but the 47/48re give you over drive.. which out off all the car manufactures that I looked up, has the lowest numerical drive gear at .69 overdrive. allowing for the cummins to cruise at 75 and still get good fuel milage.

Dodge also offers the Manual tranny, Much stronger than the auto, and you need no electronics. you shift and it goes. I chose the auto because I did not want to have to shift while on a hill, or in traffic, and I didnt want to modify the firewall or trans tunnel for the additional foot petal, hyd. resivore, and mounts.

With the Auto and the stand alone computer, Ill beable to by pass the engine magment, get my correct speed with out a seperate box, have 2 sets of custom shift points, the ability to start out in any gear, it can also be hooked up to a computer for on the fly changes if needed. so no need for a preformance chip, when you can change it anytime yourself.
 
oh ok, i forgot that the 80 would be a auto...yea, not really worth all the trouble to convert it to a stick
 
nice man cant wait to see more!

midnight landscaping comes to mind when talking about HOA :D

Well, After many talks and disscussions and setbacks, Im going to be getting a pair of loaner portals so I can at least get the rest of the truck up and runnig, untill the final ones are compleated. Ive been waiting on the axles before I weld in the engine and drive train mounts. After that Ill get the Radiator, Fuel tanks and Intercooler installed. I figure this should take no more than 3 months after I receve the loner axles, which should put me in the month of June or July.
If I would have known it would have taken this long.. I would have waitied to pull out the Toyota engine this year. Oh well, Live and lern eh?
 
Man that sucks, what a sweet build. Can't wait to see this up and running. Hope everything else goes smoothly.
 
Yes, It is indeed time for an update.. It has been over a year now, about 15 Months since the last time I have driven my cruiser before I parked her on the side of the street and began disassembling her.
I thought great, it will be ready by June, no July... ok I can wait till October, November great, right before surf and turf, before Christmass you say.. no problem, its my x-mas preasent, .. Feburary, well ive waiting this long, April the magical month, new picts, new updates, an actuall set being used on the trail. should be shipping soon. Well its may now.. and this time it sounds like the temporary axles should be shipping out soon. .. soon as in this month.. If not, well, Its ok, There has been much going on inbetween then and now. Patience seems to be the key.

The extra time as also giving me time to ponder what to do with the rest of the truck. Changes here and there, upgrades downgrades, In the end it all comes down to time and $$$. I will say it has taken a lot longer than expected, but only because I have been advised to wait on the compleation of the build untill i get the axles so everything else will be in align with the drivetrain. This has cost a lot of time, but better to wait then to tare the engine out again and reweld everywhere.

Its not much af an update, cept for that the axles should be shipping to me this month, with in the next 2 weeks. But this is where I am today and how I got there, there are a few picts of the truck Portal-Tek has on thier website with the axles bolted on front and rear. It looks very professionaly done, almost stock looking.. at least I think it does.

Ill see if i can get a few picts and more info to post up with in a day or two.

P.S. yes, they will be the same as the pictures in your link.
 
Man Ron you have about 1000% more patients than I. I would have told them to shove it along time ago!! 10K and you have to wait a year or so to get axles....that sucks!!
 
That is some serious bull****, do they have to mine the metal they use to make them or something? Can they only be worked on under a full moon?
 
Dude, please tell me you're still not waiting? I know I'm making a big assumption, and I'm certainly not in on your conversations w/ Portal tek, but I'm gonna call full-on BS on them ever coming through for you.
What's it now, 1 1/2 years?
I think your patience is being taken advantage of, and then some.
 
Yes I am still Waiting..:crybaby: but... I did give them some measurements for the axles.:grinpimp: So I am hoping that something is in the works.. Though... I cant seem to get ahold of anyone as of late.. :confused: I think they might have left the country... :ban: Hmmm.... Maybe they are personally checking up on thier equipment.
Unfortuantaly, All of this waiting time has hindered alot of my built time.. I cant finish anything untill I get thies axles. So I unintentionally went out and bought a new car for a really good price... only to realise later... :doh: I could have used that money for the Truck. I keep doing that.. speding all my money elseware.
So.. I now have 2 projects just sitting at my house. 1 dodge charger thats waiting for me to win the lottery inorder to finish, and now my Landcruiser..
So.. ... .. Yes, I am still waiting .

Though I do here that coolcruiserfj40 is getting some parts sent in. Well have to wait and see.

Damn dude! How can you stand not driving it? That is a sweet ride! It's been so long!
 
Just found this thread and thought it was going to end with finally got the axles and everything is running great and I am getting 23 mpg :). But that happy ending has yet to transpire. How can portal-tech stay in business without delivering a product in 18months? about the only bright side to this is your back on budget 10K per year. but that is hardly a consolation. dont think I would have been as patient as you.

I Think you should post up portal tech's number so everyone that reads this thread can call them and ask when they are delivering. :idea:

best of luck on finishing before 2008
 
Well, The good news is that I got ahold of someone. :) Dont know where Russ is.. I think hes super buzy.. But I did get ahold of Rob. So I was able to get in the rest of my measurments in... I should here something monday..
Since I have changed the entire drivetrain from toyota to dodge and ford, I think i have a Toyordge.:rolleyes: Well, inorder to get everything to work around the dodge transmission., I need to move the front pumpkin over 3 more inches to the right. But im only moving the alxes out 2" on each side, so well see if this can happen with out causing too much problems with the suspension. So they are going to use Russes 80 for the mock up. I need the 2-3" over so the front axle doesent chew up my tranny pan, and I wont have to cut so far into the custom tranny pan I just bought.

I also just got a copy of Australian 4wd monthly in a few days ago... Marks adapters also has portal axles out.. looks like they are starting at around 16,000 aud.
 
PORTAL-TEK portal tek AXLES

Who all has these axles, is due these axles (has deposit in ), or waiting on parts??
