Isuzu 4BD1-T

This is my Isuzu 4bd1t that I spent all summer rebuilding and it is finally running. This is my first diesel engine rebuild so it was a pretty steep learning curve.

There is a guy building adapters for NV4500. His site is 4bdconversions

This engine is from an 89 Isuzu NPR

Actually, this is a used engine from 1989 that I spent a few months rebuilding myself over last summer. I wish we could get these new here as well.

Yes, I put it in my 85 fj60 with a H55F 5 speed. I finished it up just before the holidays and now have about 3000 miles on it. I love it! It is still breaking in but I am getting about 25 to 26 mpg on average. I am running 35 inch tires with a spring over lift so this gives me a little better final drive ratio. Are you going to keep the auto or convert to standard? If you keep the auto tranny you will probably have to convert to chevy 700r to get it to mate up to the Isuzu adapter. Don

I guess the dog doesn't care for it too well!

@73SDR

You're right, she didn't. I didn't know she was back there until I looked at the video and it was too late. :-)

Kudos sir, kudos. Someday my '73 FJ40 will sound like your FJ60.

Job VERY well done.

what year 4B motor is that? out of an NPR? im planning on building a tow rig and using a NV4500 behind it and want it simple, no electronics etc....

thanks

Really perfect. one kick start shows fuel pump perfect. no black smoke. Good.

But not good for the dog. shock.

@longbowdon Nice job right there brother! Where can i buy one of them? Thank you.

Great post.

I want to do the same swap into my FJ60 - what transmission / transfer are you using? will a Toyots 5 speed mate up to this engine? How is the power in the truck after the install? Any clearance / oil pan issues?

Thanks

Disculpa, yo tengo un isuzu 4db1 pero vibra bastante. Lo coloque en un Chevrolet 1980 y caminando funciona excelente pero cuando estoy en un alto todo el automovil vibra bastante. Sabe usted o alguien mas como puedo eliminar esa vibracion? Gracias de antemano

@longbowdon thanks for the update. I already have the FJ62 with an H55f, 5 inch lift, 35's, so it sounds like it will be very similar to yours. I have stock 4.11 gears, hopefully that will work as well with this engine.

Sounds great. If the 2F in my 60 dies I'll have to go this route.
