Hey everyone, I’m trying to get some help with some ideas and best mods. I’m currently on my third deployed to Iraq and I’m having Bent Metal Customs in Washington swap my engine over to the 4BTA. I’m hoping when I head home my truck will be finished. Over the next month and a half I will be updating this thread with the progress Bent Metal Customs makes.

The engine I bought is a 2005 4BTA 130HP CPL 1839, I’m planning on using a Dodge Getrag 360 I bought off Ebay with a Ford NP205.

My plan is to get feedback from you guys on the site for ideas on best gauges, axle ratio, fan setups, vacuum for power steering, air conditioning, governor spring, top mount intercooler heater hoses. Ect

Here’s a pic of the engine mounted and the transmission. The engine sits really well inside the engine bay with no body lift, There is about 2" of space from the front of the clutch fan to the back of the radiator, however it’s very tall and is almost touching my cross over steering and E-locker. The transmission is about 8-10" shorter than the Toyota R150F and you can see its going to need a bent shifter or a relocation bracket of some sorts.

Sorry no new pics yet…

Anyone know the weight of the 4BT/6BT flywheels? I’m guessing around 40-50 lbs. I was thinking if they are really heavy, having a custom flywheel made around 25-30lbs would have quicker acceleration. I’m planning on running a Dodge Dana 70 rear with 3.54 gears so ill be running around 1880RPMs at 75 MPH with 35” tires. I was thinking the lighter flywheel with help out a lot more since I’m not planning on towing anything crazy and this is going to be my daily driver.

Other upgrades I’m planning for next year when this is finished, getting dynode at dynamite diesels... New cam from hamilton cams… turbo upgrade and new injectors I’m also looking for a cut down individual runner intake plenum http://www.puredieselpower.com/cata...498-dodge-59l-valve-cummins-custom-individual-runner-intake-plenum-p-25147.html hopefully these upgrades will help me get to 200hp and drive like my tuck did with the 5vz Toyota engine.

Im still at Fort Sill, Ok for school. I wont be back in washington tell next month and i dont have any new pics. However i bought an AC kit from profitt's crusers, gear mounted Vacuum pump and PS pump.

Anyone know the partnumbers for the brackets for the gear mounted vacuum pump and the powersteering pump that gets mounted behind it?

From what i've read on here it'll just add a whole new level of complexity. I'm not even sure it's possible.. Sure it can probably be done with enough money and know how, but the ISB is completely computer controlled, so you'd need to add all the electronic/computer side of it as well. I've read that the 16v head doesn't even flow as well as the 8v head... how much truth there is in that, idk. If it were me, i'd just stick with the 8v head. WHOLE hell of a lot easier and cheaper to tinker with..

if you can run a cr head on a 24v with a p-pump, why not on a 4bt? You would have to change your pistons though. I have been debating doing this as well. I have a ve pump though, so it would probably not be worth it for me.

16V Head

I had thought of doing this on my p-pumped 4bt But afer doing some research
I think the only benifit would be the neat factor but their is nothing wrong with that :D
but you would have to change pistons get custom injector lines made
then have the pop pressure on the CR injectors set for the P-Pump.
as far as performance a well worked 2V head will flow better than the 4V
but it's all in what you want.
