So I'm finally finishing the\\ purchase of a great looking 1987 FJ60 here in Oregon. I will now spend a lot of time (more even than I have already) researching and considering options for a diesel swap.

My goal is basically converting this nice FJ60 over to a diesel, with pretty good fuel efficiency, good highway cruising speed and enough power for commuting in ~70mph traffic without getting stuck in the slowmo lane behind semi trucks going 50. Bring on the flames, but this really isn't going to be a wheelin rig, as much as a utility rig that I'd love to get good enough gas mileage that I could commute with it instead of my 'fun' car. Primary uses will be occasional trips to home depot, maybe a move every 4 or 5 years when new homes come along, and ski/snowboarding and camping trips and road trips.
I will run biodiesel in it, if anything else to support American farmers. Okay, let's cut to the chase:

I've seen several rusted out but 'running good' BJ60's up in BC with the H55 already in it. I am aware of the fact that the H55 is pretty easy to swap into my vehicle because of the Driveshaft length in the late model 60's. The question is what options motor wise would I have? I would consider rebuilding bottom up whatever 3b comes with the car, and a good turbo to make it right.

Would there be a major difference between early model BJ's <'84 and late model >'84 ones as far as swapping is concerned? Would it be in my best interest to try and find an 85 BJ or a HJ for that matter? I am aware of the differences between the designs of the two motors and the cooling method the 3b uses being a good feature especially for turbos, as well as the sleeved cyls being a nice feature for rebuilds. That's why I lean towards the BJ. Swap wise, is the H series just that much nicer to do, that it would sway some of you towards it just for the fact less fabrication would be involved?

There's another route I've considered. The 'do it different' route, or not so much different from others, so much as different than toyota or the factory. I've looked into the cummins 4bt and considered the fabrication and cost associated with going this route, as well as the mercedes 602 series, and the bulletproofness of that motor. All in all, I've read much of what people have to say already, but I'd really like to start a more self centered discussion. Call me self absorbed :D :o I guess I just am.

Thanks for reading. Thanks more for input :beer::popcorn:

Let me start by saying that my experience is limited. I own a BJ70 and an HJ60, and have worked on a number of other BJs, mostly doing basic stuff, like head swaps.
the HJ we've build up from the beginning though, since it was a complete wreck, so I can say a little bit more about that (https://forum.ih8mud.com/showthread.php?t=66496&highlight=hj60+build).

First, many, many HJs run turbos in australia for many 100ks of miles, so I am not convinced the piston skirt cooling in the B engines makes such a difference.

I like both, the 3B and the turboed 2H in my trucks, of course the 2H has loads more power. You can actually accelerate in 5th gear at 70 mph to overtake at a good speed-but as I said, the 3B does not have a turbo.

Both engines are rebuildable, and the kits cost the same.

In the end the economy is the same on both trucks, and I think you will be happier with the bigger engine for a truck as heavy as a 60 series (famous quote: There is no replacement for displacement).

If you get the donor truck, a swap is not that hard. You will need the wiring, gauges, relays, and engine.
The advantage of the 2H engine is that the pilot bearing and spline count to the transmission are identical to a 2F engine, so if you buy a H55F for a 2F, it will bolt right up to the 2H bellhousing.

parts for both engines are readily available in the US, Canada, and Australia.

Canadian HJ60s were 24Volts, whereas Canadina BJ60s were 12 Volts. HJ60s in most other parts of the world were 12Volts.

Engine mounts will not be identical, but they are swappable.

It's true. I do love the 6. HJ to FJ very much at the top of my list as well :whoops: didn't put it in the title though.
 
a few things to consider,

-the pre 10/85 H55's use some different internals so if you buy a high mileage truck (donor) the tranmission input swap or rebuild could take more time and $.

-the driveline changes for about anything are under $250 at a high number. no one should be afraid of a H55 conversion except in earlier fj40's (size, frame tubes)

-2H's can crack rings and some can loose vast amounts of power.

-a donor JDM engine may be the best way to stumble into a turbo 13B-T, 12H-T, or sometimes a 3B can be had.

-fabbing motor mounts and using the existing tranmission crossmember as starting point is <1 banana job. setting the engine is 3% of the conversion. wiring is 65%.

-a/c is rare in CDN BJ60's and sourcing parts can be impossible.

-12 to 24 v conversions have been covered in detail and they are essentially a non issue.

-25 mpg is realistic high highway for us gallons and us miles with the best conversion. do not believe 30+ quotes as imperial gallons use 40 oz qt vs 32 oz us qt., therefore many others (our brother canucks) quote 20% more mpg.

keep us posted!

Unfortunately the pics weren't coming up for me anymore, but I believe stickboy is in Idaho so he is relatively close to you and could be visited to see the real deal.

EDIT: I forgot to say I think the 13BT+H55F is the way to go. If you're not towing and not doing hardcore offroading (and even then, I'd spend money on gearing rather than HP), the 13BT is all you need and will get great mileage.

Too bad... I drove my recent FJ to BJ60 through Beaverton yesterday enroute from Tillamook back to Seattle... it was the maiden voyage for my rig since the swap. Next time I'm in the greater Portland area or you're up here in Seattle I'd be happy to show you my results... oh, and with 33 Mud Kings and a 5" lift I still managed 22MPG for the trip. PM me if you'd like to see her!
 
Funny you mention that. I'm going to a Maxima meet (hopefully) at Fry's electronics in Renton (I think?) or wherever your fry's is on Sunday.

thanks. I have already read that entire thread, as well as probably every other swap thread in here. I spend a lot of time searching and reading through threads in forums. It's my "book".

i'm well aware, as I stated above, thank you though

I figured as much. I have read through about my model year being direct swap for the H55. I imagine it can't be any harder than swapping my FWD maxima transmission..

-2H's can crack rings and some can loose vast amounts of power.

I didn't really read much into this... It's my experience that when a motor is built (rebuilt) correctly, problems like this are much less likely. I would probably spend the extra money taking such preventative measures.

-a donor JDM engine may be the best way to stumble into a turbo 13B-T, 12H-T, or sometimes a 3B can be had.

If you read my intro thread, you'd see my father and I are diving into an importing business. My entire family resides in Tokyo. We are looking into doing this already.

-fabbing motor mounts and using the existing tranmission crossmember as starting point is <1 banana job. setting the engine is 3% of the conversion. wiring is 65%.

It's a saying known to me and possibly others that 'for some people, wiring and electrical is a nightmare, and fabbing is easy. For others it's a flip. For even others still it's all the same.' I don't know exactly where I'd fit into this, but I can tell you I've been flip-flopping my major in school between electrical and mechanical engineering (though this in no way means I have that under my belt yet, it does mean I don't mind either really)

-a/c is rare in CDN BJ60's and sourcing parts can be impossible.

That's a bit of a dissapointment. What about HJs? I live in Oregon, we don't use the A/C much more than 2-3 months out of the year.

-12 to 24 v conversions have been covered in detail and they are essentially a non issue.

That's a bit of a relief. This kind of stuff to me is more of a fun project than an 'issue' This whole swap will be kind of a spare-time deal, a learning experience, and most of all for 'fun'

-25 mpg is realistic high highway for us gallons and us miles with the best conversion. do not believe 30+ quotes as imperial gallons use 40 oz qt vs 32 oz us qt., therefore many others (our brother canucks) quote 20% more mpg.

Well.. I would hope for more, but I wouldn't expect it in a rig like this. It'd still be the same as my Maxima, which is good enough for me. This would definately be a top deciding factor for me, right next to power.


keep us posted!

I will try my best!!
