what do u thing think off fitting an 8.3 l cummins in our trucks would it work how much work is it. is it even posible. but it would be cool lots of power already in it u could bump up power and boost and would last its inline six same block and stuff. bout might be to heavy. dont know what u guys think.

 

I'm not entirely sure, but I don't think it's the same block. It's been put in a Ferd, but from everything I've heard it'd be a lot of work. It's one of my goals after getting through college.

 

the N14/855 is a big motor, same with the M11, they weigh alot more than a 6bt, and they weigh just shy of 3000 lbs fully spec'd.

 

Those are different than the 8.3 though.

 

true, i dont know what i was thinking.

 

8.3l isnt too much bigger, i have wondered the same thing, and even talked to a cummins field tech. he said they are rated for more than they would actually handle, but thought they would be awsome in a pick-up too. i personally think it can be done, and would like to see it.

 

I've often pondered about this too. The p-pumped ones still use the same pump as on the 5.9l correct? And are the injector bores the same? If so, modding would be AWESOME!

 

look at them side by side the 8.3 makes the 5.9 look like a toy. it would be a tight squeeze

 

When we build my truck...that was an option.The CT is only about 5 inches longer and the height about 3inches...cant really remember,but it would have fitted in my F250.

However,having owned both engines and worked them in the same applications,the BT is the better engine for a truck.Make no mistake,the CT is waaaaay stronger off the bat and at low rpm it will out torque the BT by far.

Massive midrange as well,but its hard to explain,at 1800 rpm the CT gets "cumbersome" if i can call it that.This is where the BT shines,and the only reason we chose it over the CT.The BT loves to rev.The CT hates it.

Its in the sound of the motor.When the BT stops revving at the governor,it feels like its too early to stop now....whereas you feel like you are hurting a CT at 2200rpm.

I reckon if you want a lugger that will pull almost anything by merely dumping the clutch,and you have ratios that will let it run at max speed around 1700rpm,youd be as happy as a pig in ****,but for a truck that you want to mash between robots and do the dirty work....the BT is the winner.

Its just a better all rounder.

 

Sounds like a sweet idea, but the weight concerns me

 

Engine weight shouldn't be a problem that an extra leaf or so won't cure. The 6CTA weighs in at 1360 pounds. The added weight of a strong enough transmissiom may be another story. The fellows at work and I have been talking about doing this but, no one is willing to sacrafice a truck for the project. personally I think a 6CTA in front of an Allison six speed would be the bomb. Who needs rpm if the gearing is right? I doubt that it would be a dragster but, oh! what a sled puller it could be.

 

yes thats right more springs keep rpm the same but add more power. u dont need to make motor spin fast to go faster just power and getting it to the ground in the right way by gears . u could put big power in it and if u hav the allison trans with 6speed would fast stronge and fuel would be great cuz it has 6 gears

 

I would like to see a 8 speed with a double low that would be cool.

 

8 speed would be sweet it should be low in 8 gear make the truck run on idle doing 130 km fuel would be big saveings probly get over 35 mpg with mods

 

Step away from the coffee!!!
