cummins diesel swap?
#121
As far as a 4bt into a pickup or 4runner I would have to agree that it would be overkill. Not to mention the fact that it is nearly a 800 pound engine. I have also heard that the engine shakes like no other.

i can understand all the opposition, but there are plenty of people who put 4bts in light trucks.

I've extensively researched the 4bt for the better part of a year, made a lot of phone calls yada yada.... and it all comes down to size and weight. It is not at all a feasible engine for a toyota, as the frames are a weak point, and the low end shake of a 4bt would eventually destroy the frame. The engine is also too tall and would hang down too low to be useable off-road. If it's going into a 2wd truck thats just for the street, it would maybe be okay, but for a 4x4 that wants to get ˟˟˟˟˟ done, its just too big. There are many smaller engines with enough power for this truck that would work much better. Not to mention that the shear torque of the 4bt would destroy any stock toyota parts. By the time you beef up your frame entirely, narrow some dana 60's, get an nv4500 and dana 300 and new drive shafts, your out a couple grand. Then you have to squeeze out another $1500-$2000 just for the 4bt. I can go on all day with cons to this swap, and trust me, I used to be the guy who only wanted to focus on the pro's, but theres just too many cons for this motor.

this is a 4bt in a dakota. used fluid filled motor mounts in i believe two points to minimize vibration
Pulling on a heavy load i see potential for problems, but heeavvy. As far as turning its own tires, i see no issues. 4BT torque is around 350ft-lb this is just as much as a built chevy 350 and i have known people who have accomplished this, and the hp is around the same, while 4bts is high 100s.
Weight for a 4bt is like 800lbs wet, chevy 350 is around 600. Obviously that would have to be accounted for.
the frame is fully boxed, but yes, extra cross members and a few gussets in a few places and that problem should be minimized.
Any engine swap is going to have its challenges, especially when you are going so far outside what is normally in the vehicle. i think that about sums it up. In fact, looking over that dakota thread should clear up many of the what ifs, considering the dakotas frame is weaker than the pickups.(drivetrain as well)
in closing, yes, there are easier swaps, but, you just have to weight the options and prepare for whatever you plan it all will be well.

you can do a 6cyl cummins but theres some major fab and body work going into it. 4bt cummins is more practical, thats what i want to do, finding one within 100 miles of my area is my biggest challenge

not to mention you posted 2 rangers, a commanche, and an s10, which are all not toyotas. They all have different frames and engine compartments, not to mention that yellow ranger is 2wd, which makes an engine swap 50 times easier since you dont have to worry about oil pan/differential interference.

i got the 4bt Cummings in my 86 4x4 works great i have pulled a few heavy trailers just fine just dose not stop good with out the engine brake. installed the engine brake (jakebrake) works good. i have put 28,000 since i did the swap and haven't had any issues. except when i raced it the last time i launched at 2,500 rpms and broke 1st and 2nd gear in the trains. got a heaver duty trains and its going just fine

hmm.. was that really necessary? there are grammatical errors, but the meaning is understood, so what is the difference.

Pick up an issue of Diesel Power Magazine and read through the online forum guru article. It states right in there that you will not be respected if you cannot speak grammatically correct online. I agree with AH64ID in the sense that, if you don't even know the name of the engine, how can you be trusted with information about it? Calling a Cummins a Cummings is just one of my biggest pet peeve's. Sorry 'bout it. It's like calling me Joel instead of Joe.

i never said that i could spell so what the difference.. when spell check auto corrects it that way.
the trans i was running pulled fine. i have pulled my 773 bobcat with it just to see if it would. my new trans is a lot heaver duty i have done 5 or 6 3,200 rpm launches in 4 high and have had any problems with it about step up the turbo with custom twins
aye, thank you for the input, and too funny about the trans, curious how it held up pulling the heavier loads
