woouu not an easy homework .. but I will !
I have been looking into this as bought a 13BT rebuilder awhile ago and could soon be buying a 14B and rebuilding it as a 14BTT ( just have to stop being in-decisive ), as far as i have found out >>>
The 13BT & 14BT have the same bore size of 102mm , but the 14BT has a 6mm longer stroke crankshaft giving it the extra CC . The 15B versions have the same cranks as the 14B's but they have a bigger bore aswell . 15B's are harder to come by & cost a bit more becuase of the extra size & Multi-valve head , etc
I think the 15B block is a wee bit different than the ones before it , but curious if they are same head bolt pattern , wonder if the 15B is either "dry" or "wet" sleeve ?
As far as a 14B crank going into a 3B, 13BT block- give it a month & the answer could well be on here, as will be waiting to get the 13BT frieghted down here ( i should have already organised , slack ass me ) once snailtrail gets back from his wicked holiday in the Himalayas, etc

This morning I went to a diesel engine parts supplier & Jap diesel engine importers >>>
firstly went to the diesel engine parts supplier and had a look at New 15BT pistons & liners compared to the 13BT . both were on the bench that has just been unwrapped . the 15BT ( but that is stated as finished , once the sleeve has been installed bored & honed- they are like 1.2mm less and are called semi-finished ) has a sleeve of 108mm comapred to the 13BT of 102mm. funnly enough the whole 13Bt sleeve virtually slips snugly into the 15Bt sleeve , plus the 15BT sleeve is just a straight tube , when the 13Bt is a wee bit shorter & has a step and a ridge at the top of it like and O-ring .
then went to the Diesel importer , he told me the 15BT
s are really hard to come bye as they are late model , he had a 15B non turbo sitting there , i had a look at it .
Curious as to whether a 15B head will fit on a 13 &14B block , will go back to the engine parts place and see if they have a 15B head there and caompare it to the 13BT & compare head gaskets .
off to work now as seriously running late-lol

14 b engine should be a straight swap for a 3b engine.
They use the same bel housing bolt pattern, and even the engine mount locations should be the same.
Main difference is that the vacuum pump is integrated into the front case. so the alternator doesn't need a vacuum pump.
Thats good cause you are not limited in choice of alternators.
Even the starters are the same.
I'm not sure the radiator capacity is the same though, but then again. its only a few more ponies difference, but with alot more torque.
A 14b Turbo conversion must be a super strong engine.
A friends 13 b with a turbo kit runs super . Good speed on freeway , Cruises at 70 mph, and great power off road. The added torque lets him run 4:10 gears and run 38" ground hawgs with a transfer case reduction gears.
It's still a low reving truck engine, not as exciting as a hz motor but it does the job well.
Cheers.

looks like i could be gettn a 14B soon & rebuild as a 14BT with turbo rods & custom forged pistons. its not hard to speed up some diesel engines , their just like petrol/gas engines in that stock engines are similar , once you start to improve certain areas like exhaust , filters , intercooler & boost , injectors & pump ,etc - its not long before you start smoking your tires . thing is most people just do the stock rebuild with diesels and wonder why they are slow , jump onto some peformance diesel sites and you'll learn otherwise , like a site called competitiondiesel.com , they have clips of big dodge rams with 5.9ltr turbo cummins dragging off new mustangs & Vipers on the dragstrip !
The thing is that once you do that you weaken the engines as well, so you have to be able to compromise and have a bit of performance and reliability (If that's what you want). Honestly I bought a diesel for the long life, reliability and torque. If I wanted to smoke a mustang off the line, I would have bought an RX-7.
but you can't tow a heavy trailer full of stuff with an RX7 can you ? depends what diesel you buy really , there are alot of slow sluggers around , all depends what you want in the end, you can still build a performance diesel engine that will still be able to clock up 200,000 miles plus .

I'm pretty sure that is a money question .. why not with the apropiate reduction you canpull a heavy truck with RX-7 engine . ?
I believe you do a HP toy diesel engine and good reliablillity it's a metter of money ..
plus diesel technology has taken off in a major way the last 5 yrs , with oil prices the way they are , people are looking for more efficient engine designs & with cleaner emissions and diesel's seem like the way to go for now .
you can HOTrod any engine really , Pushrod V8's were popular some time ago , now its right across the board . just like you can "Hop Up" Diesel perfomance instead of being a Slug , most people have experience with gas/petrol engines , reason why theres not that much Performance Diesel information around !

So how much gear reduction would you need ro Tow a B-double road train traliers behind an RX7 ? what like 5,000:1 & what about the brakes & everything else - LOL

Bumping this - any work in putting a 14b crank in a 3b??
Its fairly uncharted territory on this forum. Wiki and other places have the bore and stroke for each B engine. Some of them are restroked versions of smaller B engines. And you would have to note compression ratios for direct and indirect engines. And there is at least 2 types of 3B.
