Great startup! I gotta ask since I’m rebuilding a 4bt for the first time. What did you give 12v to fire up the motor? Obviously the starter, but something to the injection pump? Could you explain? I’d love to test run it before I put it back in the forklift
Just fuel to the lift pump on the block, 12v to the fuel shut off solenoid and two fully charged 12v batteries in parallel to wing that sucker on over!
Hello! Could you please tell me what model of turbocharger is mounted on the engine, along with the numbers on the nameplate? I'm also interested in the size of the turbo housing. 6; 7; or maybe 8.5 cm. Regards!
That turbo is a Holset HX30w but with a 12cm housing. It is supposed to be pretty lazy so I switched to a Holset HX30w with the 6cm exhaust housing. My new one is a chinese copy and seems to work well.
Contrary to what Ed said, I bought it off craigslist. Guy was asking $1700 for it, I gave him $1500. I had to get an on road injection pump so that was another $700 for a brand new one (lucked out). I also bought a chinese HX30w for $200 plus $150 for an intercooler kit. Time and labor were all me of course. I would say $2500 or so installed. The little things add up. Like you have to build your own AC brackets your own alternator brackets and stuff. I have a welder and can stick metal together so that helps.
@@mikegrassi4537 you'll need an onroad injection pump plus a matching timing gear cover. If your engine has a VE pump already, then get a VE pump that has the onroad governor and you are set. They arent cheap. I would suggest hopping on 4btswaps.com and do a bunch of research. Everything is pretty much covered there.
It usually does, but Cummins at the time did some weird stuff when it was transitioning to the QSB series. This model is the QSB4.5-30 and originally came with a computer controlled VP-30 injection pump.
I stand corrected. You got a rare one there. You basically got a stroked 4BT there since you put a mechanical injection put on it. That thing needs a P-pump!

Looks exactly like a 3.9, never heard of a 4.5
The last 3 sec of the vid makes it 😂
Very nice ❤️👍
4.5. Interesting

you make sure to tap the death pin back in, and install it's keeper?
Yep, I did that months ago. I assume you mean Killer Dowel Pin...
@@marshallnoise3557 yes the KDP
Literally waiting on my KDP kit for my 4bt bread truck lol
So, just what can that be used for?
A swap into my F150. Muahahahahahahahaha!!!!
Turbo shaking🤣🤣
Where did you get your 4bt? and how much did you roughly pay?
It was free his uncle passed and he gave it away.

@@marshallnoise3557so that was an industrial 4b? i just picked one up..trying to learn what i need to put it in a truck

@@marshallnoise3557 thank you i need to do my homework
I thought the 4bt came only in 3.9l package?

@@marshallnoise3557 ah I had no idea about that.
@@plainsabertooth7828 I honestly don't think it has all that much more torque, but it ran good until it didn't!
@marshallnoise if I recall the original 3.9l had about 105hp?
@@plainsabertooth7828 Indeed. This one is rated at 110hp but 305 ft lbs. Now that I have a VE pump on it, it's any one's guess.
You better put the carburetor back on it before you start it again....
Lol it don't have a carb lol its diesel all that goes there is pipe to turbo to connect turbo to motor lol 😆
@@supremeautomotive6749 Then he better make sure that the spark plugs and the distributor are in good working order.
4.5L? Not 3.9? 🤔
Yep! I believe the designation is QSB4.5-30.
Learn something new every damn day.. thanks for sharing.
All 4BTs are 3.9L 8 valve engines. The QSB 4.5 is a 16 valve engine
@@pablo_santos29 do some duck duck going, especially the model number I listed. You will come away with a different understanding.
