Default 98 Dakota cummins 3.3 build

I have been gathering parts for some time to do this build and its time to pull the plug

98 2wd Dakota ext cab manual trans slt

the tranny on my Dakota locked up so I figured now is a good time to get started

what I gathered
Cummins 3.3 fresh build form a student at a tech school in PA
adapter kit for trans from Phoenix conversions in Nebraska
transmission from a v8 Dakota needed the bell-housing bolt pattern
the rest of the stuff fuel pump filter inter-cooler motor mounts misc fittings from our old friend EBAY

below are a couple of links one is where I post my pictures and the second is the engine running before I bought it

Only thing is its gonna lack a little bit in the power department. The 3.9 cummins is a popular choice for swaps. Them being a baby brother to the 5.9 makes them a decent motor that is very reliable. Either way it will be a different swap and will be a fun project! Keep us posted and take TONS of pics

80 or 85hp, 215ft-lbs torque I believe is what they have.

What injection pump does it have?

I was going to go with a 4 bt b3.3 is a little better fit under the hood should do the first fit this weekend that is if i get the 3.9 out this week

You sir have just gave me a reason to keep my single cab dakota, i totally forgot about the 4 cylinder cummins, i think the 2.5 jeep engine isnt strong enough, but one of these would be interesting in a Dakota... i may seriously consider this after i get my accord & RF900 finished..

Lots of pics plz

personally the 3.9 is a better idea for most mainly due to parts availability. And they are really common because they are in most UPS and bread trucks.

there are several reasons I didn't go with a 3.9
the height of that motor is the same as my 5.9 so I would either have do a body lift or some other radical modification or have a 8" hood scoop
I don't believe that I would be able to achieve the fuel mpg i am shooting for
this is an industrial engine so they are known for better fuel consumption than their on the road counterparts and i could use a stock Dakota trans otherwise I would need a nv4500 now we are talking about tunnel mods also

believe me I researched both engines for weeks before i bought this one
