84-92 4bt swap


How do I make my 4BT move like this?

🤔 this truck isnt moving as fast as the first time I watched the video..... must have been a sped up video before.
 
I would suggest robbing a bank and have the fear of going to jail be real.

An Eaton m112 supercharger and a HX40 turbo would be a good start. Not that I have any compound boost plans or anything. ;)

I figure fire ring, 5.9 rods and pistons, head studs/work cam. And p pump with a bigger turbo and intercooler would be a good start. I dont know if a zf5 will handle it and np205 I may have to go nv4500 etc...
 
Obviously the guy had to rob a bank to pay for his engine upgrades...
 
Out of curiosity has anyone ever seen a 3.0 ecodiesel from a ram put in anything? I never thought they would be a good engine but maybe I am mistaken. Thoughts?
 
Or depending on the year TDI I find I think the early 2.5 dodges have the same bellhousing pattern.

I know you're a old mopar lover like myself but that engine is a fiat, not even a Chyrsler design while they were owned by fiat but a straight up Italian made fiat engine. I wouldn't go near that thing with a 50 foot pole. German diesel eh ok maybe they make some reliable stuff, but italian? No you're insane...
 
🤷‍♂️ 4bts are getting to be a pain to find so I wanna look at some other more available options. Before I get to far down the line and im rebuilding a 5k motor.
 
Is the ecodiesel really more viable? Even if you find one, what are the parts cost and availability for those things? :dunno:

I've never driven one or worked on one but I've dealt with other fiat crap before so I'm leary with anything they make. And again I don't mean chrysler products owned by fiat, I mean the things fiat actually designed and built.
 
Considered a cummins R2.8 crate engine? I'm not super familiar with diesels, but I've seen this crate engine they released a couple of years ago.
 
I found 2 wrecked rams with then in it bot really cheap but I know I could get my hands on one.

That r2.8 is just as expensive as a rebuilt 4bt. So its a toss up.
 
Generation 1 trucks, when you will be utilizing a completely different power train and straight axles, the 2wd trucks are usually cheaper and in better shape..

so for work like this they tend to be better candidates.

They have a smaller k member so exhaust fitments, oilpan and starter room are generally better ....

it's when you just want a sas.....a 4x4 is obviously a better start.

With that said you should sell me the one you just found.:)....clearly you don't want that thing.


As to the r2.8. Money well spent .. depending on goals. A very sound investment.

A 4bt in its best form sux to daily in regards to NVH.. ...an obnoxious pos.

From a reliability stand point ... accessory drive withstanding...they...the 4bt are epic.

But compared to a vw or benz for REAL WORLD USE.....they are garbage stockish for stockish.

But in the case of a ranger on sub 40 inch tires that you want to ACTUALLY drive on the road, the r2.8 excells.

For max performance builds the 6bt is the way to go. They are generally cheaper all the way around...and easier to procure. So for the money to do a 230hp 4bt... go 6bt



The reason I have tolerated the humvee engines so long...stock for stock, it actually blows a 4bt or 6bt away to 50 ish mph...with no turbo....is quieter, and much better NVH....I have run stock 4bt Jeeps and a stock 6bt land cruiser and was surprised to outrun them ....because my truck is slower then smoke off of shit. That changed my perspective.

The 6.x early gm builds are weaker...Not as good fuel economy...and harder to start cold. .... But cheap and easy. with hand tool mods will run on alternate fuels... And under a 100 bux can renozzle the injectors.

So ..it's been 13 years . I have broke a few... But Still in there. And all for less then any cummins swap


And consider this. The later units are over 200 hp with turbo. .and hold 300 hp easily and cheaper then you can get a mechanical cummins to.. WITH BETTER NVH...and a 4l80 ...


So as always. . .your actual goals and intended use are key
 
Im thinking 353 now I might have a line on a good one..





I cant wait to really piss of the neighbors 😂 they hate the V8....
I love the sound of those Detroit diesels
