Cummins 6BT in FJ80
I know this is a question lots of people ask or wonder about.
What I want to know, Is .. Is it possable to do in an 80?
I have ready about the one in the 40. Very nice.
Nothing like going from 8-18mpg up to 28 if you tune it right.
I am a heavy machinery Diesel mechanic, so I can do all the work except for the fabbing of engine mounts and custom machining.
This is a future plan i plan to do. meaning sometime between 1-5 years from now.
I have done lots of reading and serching and studying on this...
I know that its a heavy engine and the LC is more of a light weight.
But opinions are priceless.. and you can always learn something weather you mean to or not.
My plan is to get a 90-94 cummins 6BT 12 valve from a dodge truck.
I know thier more louder than the new ones.. but I dont want to have to mess with computers.. i just dont like them telling my engine what it can or cant do.
Also .. theres no way to shut down that year of diesel unless you shut off fuel or shut off air flow. no spark needed.
The noise can be reduced by tuning also.. matched parts, exhust, intake, turbo etc.
As far as weight, I can get the block ground to remove many pounds, I can relocate the battiery(s) to the rear of the rig. (50+ lbs) more costly, a custom exhaust.. save 80lbs, rethink arb front bumper/winch, = 300lbs
and last but not least beef up the frame if needed (get rid of airbags)
So .. I dont think weight is the best excuse to use as a Dont get that cause its too heavy.
As far as adapter, tranny transfer case, etc. I donno what im gonna do there.. Yet.
Now when i open the hood of my 80.. theres a lot of room in there, Enough to stuff even a Cummins.
I can go with electric fans on the radiator, add a vacuum pump for my hydro brakes,
The motor mounts would have to be custom made and frame reinforced to take the added torque.
I would leave the axles stock for now.. dont plan on boosting 600hp and 1000lbs of torque, ... but would like around 300hp and 300-500torque.
I dont plan on racing this.. so .. I don thave to worry about Ripping anything apart from anywhere. just want the milage and the dependability of a Cummins diesel.
I have concidered the new 06 Cummins.. but Pice and avi make it a 15-20K project.. im not looking to spend that kind of money..
I plan on doing it for less than 10K
First.
Buy used Dodge Cummins 90-94 no computer on engine.
auto tranny 4x4 turbo, $2000-$4000
Find someone to do the engine swap who knows how to Fab. $500-1000
Misc. Parts and Supplies $500-!000
Tranny, transfer, install and relocation, driveline $1000-2000
I do the rest of what is needed.
Ok.. So., I am looking at an Estemated $5000 up to $8000
not to shabby concidering what you would pay for a used toyota turbo diesel with a hard to get parts and avi. + $$$ shipping and Parts.
Next...
Do i want to keep my Existing Drive Train.. or Should I beef it up.
Some people say it wont take the extra torque,
Pluss ill need a custom Bell housing $$$
If not.. Ill need to go all new (used) from the Engine to the drivelines (F&R)
Keeping the stock axels.
What do you think?
I know that I would like to do this... but Id like to here from everyone else,
I only here Its too Heavy, Its too expensive, Its too much work, go with a holden, or v8 OR AT ONLY 200-300lbs lighter,... the Duramax.
I currentaly have a 6" slee lift and 38" tires... so unless I need a body lift.. I think I should have no problems with clearence.
