wasn't sure if anyone was interested but i'll throw up a thread about my truck.
i startednt this project when i was 15. i was into diesel pretty early and i wanted something a little differerent so i came up with the idea of a small truck with a diesel. i had it built and driving by the time i was 16 with alot of help from my dad. I've been driving my dakota as a daily driver since. last year i did some mods to the engine including fuel mods, a huge intercooler, twin turbo's, and a streight piped 4 inch exhaust.
here is some pictures

some big plans for the future i want to have new axles, transmission and a race suspension.
i also picked up another 4bt with a different injection pump capable of supporting huge hp. physicaly the pump can be capable of moving enough fuel for 1000+ hp. where as my current one can't support much more than 300hp worth, it also can't handle high rpm's very well.
anyways depending on the money situation i'm either gonna build up the new engine to hopefully around the 700hp mark.

or if money is a little tight then i'll just do some smaller mods on the current setup such as a major head port and probably hook up the nitrous kit that i've had for almost two years now.

plans are to get big power and then test the strength of the rest of the parts at the 1/4 mile and replace broken parts with stronger replacment parts

I might recommend dumping that 4L80E and getting a 47RH. I can not say from personal experience but I have been on a few conversion forums, and what I hear is the chevy trans is good for stock, nothing other then that without extensive work. The 47RH on the other hand has shown over and over again that it can handle massive amounts of Cummins power... lol I'm a cummins guru and I have every intention on dropping a 4BT in my rango with a 47RH behind it.
The 47RH (note RH and NOT RE) needs no computer because it is hydraulicaly controlled, and OD can be put on solinoids. If you have any questions I can get you all the info you need to make a 47RH run all by itself... Not to mention the plethera of aftermarket Diesel specific parts for the 47RH makes it a much more viable option. After all the 4L80E only ever saw its worse diesel duty behind a Chevy turbo 6.5L, and the 47RH and its varients have been backing the Cummins since its Dodge introduction in 1989...

Just my $.02 take it for what its worth

The 47RH was fitted behind the 94 to 97 Cummins equipped rams (SECOND generation) the 1st gen 89-93 came with a NON-lockup 727 with overdrive.
I most deffinately agree a hopped up 47RH is an excellent choice just for the aftermarket parts availability and ease of use. a 47RE is the route i'm headed...
that non lockup 727 with overdrive, was a 518 model which is the SAME as a 47 RH exactly they just changed the name of them.... same tranny
Brain fart! yes that is what I meant the a518 not a 727. And yes essentially, you are correct, just no lockup option.

I can't wait to get my project off the ground, gonna do a 4BT Durango. I love the whole concept of it. Power, reliability, durability, and most importantly, fuel mileage! :drive:

hehehehe and I got the 'ol lady on board with it! lol now to collect the 3+ thousand dollars its gonna cost to pick up the parts and refresh the engine and build the tranny...
