Im interested in making a cummin's 4bt toyota crawler. it would have loads of torque and would clime like crazy with low rmps. Just not sure bout what transmission and adapters would be needed. I have seen a 4bt in a 92 yota its on youtube!

NV4500 i believe is what came behind a 4bt, if you want a stick. thats the way i would go, i hope you aren't thinking of attaching the toyota trans to it, i highly doubt that thing would survive a trip down the street (idling mind you) mated to a 4bt.

Hm, maybe thats what i was thinking.. I know you can run them behind a 4bt (no idea whats involved to mate it, if anything), a bunch of guys over on Pirate run them. It'd be a cool swap for sure, but practicality-wise, not really worth it IMO. You'll never be able to tow the kind of weight the engine was designed to pull because now you're running into frame strength/suspension issues…

Yes they don't come behind 4bt's stock, many people run them though. 4bt and 6bt's are pretty much the same except the 4bt missing 2 cylinders. 4bts are great engines though I wouldn't recommend one for a toyota pickup. They are big and heavy, unless you plan on a SAS and complete drivetrain upgrade.

For what it's worth, there is a modest 4BT Toyota Pickup running around, and by modest I mean it's got stock axles vs. full widths that make it illegal in a lot of states, and isn't a mud queen sitting on 44's. It's sitting on 35's with stock Toyota axles, and it's only getting 20-27mpg with the average being closer to 20. Not very good mileage after all! Guess it is just too heavy!

better mpg with 4bt
I would think a 4bt in a first or second generation Toyota 4x4 would get better mpg than you guys are saying. In two different half-ton Chevy 4x4 on 35' tires I've seen , they were getting 23 to 30 mpg. Both with 700R Tranny's.
And a 4bt weighs a little over 600 pounds loaded. I would definitely run my batteries on both sides next to the tailgate.
