The 4bt was manufactured with several fuel injection pumps. The 4bt is manufactured with no method of attaching a transmission, an adapter plate is needed to connect the 4bt engine to a transmission bell housing.

I have no knowledge of what injection pump and transmission/bellhousing the Venezuelan Ford truck has.

Consider using an engine and transmission from a Venezuelan Ford truck. That way, you would not be searching for adapters to attach a random transmission to the 4bt engine. In North America (USA and Canada), we have options that are getting harder to find - In your case, these options also would be expensive to ship and possibly difficult to import into your country.

The 1986 Ford F150 (see my signature below) - My 4bt came out of a 1986 Ford E350 (bread van) and had an adapter to a common Ford small block V-8 bellhousing pattern. I was able to bolt a 5 -speed overdrive transmission to it.

mine also has that bell for me it would not be difficult to import it or make it in iron myself my intrigue is in what is the limitation and what modifications should be made when mounting it in a common truck he brought a rotary injection pump I would like to know what it is what I must modify to be able to make the changes at more rpm the box that I am going to adapt is very similar to the relationship to the nv4500 but it is a 5-speed manual toyota that brings the fj-80 Land Cruiser friend thanks for answering my questions very nice of you

We have to start with some information.

Rotary pump is a partial answer - they come in different types VE (most common in trucks), CAV and probably a couple that I do not remember - In general, the governor (engine speed regulator mechanism in the injection pump) is modified by changing an internal spring.

On the transmission, I can not help. I have only done this one 4bt engine swap and it was many years ago

Send us the engine specifics, and we can help you figure out how to increase the RPM it produces. Give us a picture of the engine data plate.

As for the truck, did your 62 have a 3fe or a 3f? If you have a factory cable throttle, you can connect the cable to the VE injection pump throttle and that's pretty easy.

Which transmission? H150/H151F?

Ask questions and I can help.

friend an intrigue that I have is that in the ford truck where the engine was mounted on the dashboard the rpm meter indicated the red at 3000 rpm the mr who sold it to me told me that if I pass it at 3000 rpm the crankshaft is damaged and many more parts of the engine because that happens what modification must be done to increase the maximum range of rpm the other thing is that the engine came without intercooler the turbo is direct to the intake that intercooler you recommend mounting

The stock 3f radiator will cool the engine just fine.

To go above 3000rpm you need to put better valve springs (60# (pound) valve springs) and change the injection pump governor.

As for mounting the H151f, there is no one in the world I'm aware of that has mounted a 4BT to a H151f. You would need to machine a replacement flywheel housing to allow the H151f and its bellhousing to bolt to the engine, then figure out a custom flywheel to allow you to use the H151f 300mm clutch.

As for the intercooler, use as big of an intercooler you can fit in the truck. I used an intercooler out of a ford 6.0 diesel, but many modifications were required.

friend and where can I buy the valve springs and which one do you recommend talking about the turbo which is the most suitable model to use on the road and off the road that gives me a good push as well as the injectors
