torque.. the love of the gods... rip motor mounts, crack / break metal frames.. etc.

just looking for 15 - 20 miles per hour... more...

3:00 to 1 rear gears... or 2:80 to 1 .. BUT the truck will move from a STOP a little bit slower. every thing is a trade off.

 

Well, there is a reason Dodge didn't put the Cummins in the 1500s. The diesel won't rev as high as the gasser. You'll top the motor out pretty quick.

 

Take some pics and tell us more about the engine swap. Those 12 valves have a lotta potential when setup right.

 

well for starters here are a couple of sites that are dedicated to us diesel conversion nuts

http://www.dieselbombers.com/ http://www.4btswaps.com/forum/forum.php

first of all for what you want you can do a couple of things you want to keep the 47rh it is a manual shift trans and you wont need a stand alone computer there are a couple of final drive options you can do might give you 5 mph I would make sure you are shifting into overdrive sounds like you are not to me change the gear ratios you can change tire sizes some to achieve what you want

you can change Governor springs you should have a ve pump

I hope you did some frame and suspension work on the 1500 that engine weighs 1000lbs and stock has enough torque to twist your frame

 

Is that a 4bt you have in your dakota? I want to put one in a ram 1500 and tune it up a bit.

 

no its a b 3.3 it is a industrial engine designed by cummins and komatsu very durable and turbocharged for a full sized pickup I would recommend the 4bt 3.9 p pump engine then use a 47rh or a nv4500 for trans

 

How hard was mounting the engine? I'm not worried about electronics, but the fab work would be the hardest part for me.

 

well i used the stock tranny mound because I used a nv3500 and the littler 3.3 engine for what you a looking at I would use the stock tranny mounts the engine I would use a 4bt use some liquid filled motor mounts the pan may have to be modified but that is really no issue it is very doable and has been done already

 

he said he is running a 47 rh not a 47re if he is running a 47rh as he indicated there are a couple of ways to make overdrive work

just to clarify 47rh is a non electronic manual shift trans a 47re is the electronic shift trans


he first needs to make sure what he has if he used the trans from his donor truck then he needs to enable the overdrive and torque converter
lockup

the easiest way to make it all work is on the passenger side there is a port to test the pressure on the trans it produces about 1 psi per mph so get a 55-60 psi ac switch so when you get to 55-60 it will enable the overdrive and torque converter lockup there are some good write up's on this on diesel bombers 4bt conversions and the conversion section on ford truck enthusiasts

now if he is using the the 47re I would get a controller from http://www.fordcummins.com/ or http://www.destroked.com/ these 2 companies deal with cummins conversions



some of us feel that ford put in the 6.0 diesel so that they could be converted to a superior drive train with the cummins conversion

 

Thanks for all the advice. I just uploaded some pictures of the truck. I think my transmission might be messed up, im going to rebuild it and see how that helps. Thanks again
