3B in a 4Runner, I did it! A few questions now...

[huckthehaus]

no pics of the swap yet, camera broke, but here is a pic from a couple months ago:


questions first:
1) how do i get my efi tachometer (sending unit was the distributor) to work with the 3B's flywheel sender?
2) i currently am running the glow plugs off a 25 amp switch w/o any relay. i don't think the switch will like this in the long term. i have both the primary and secondary glow relays from a 12V 60 that i can use but there are more than 4 pins. which relay do i use and what pins? also i'm using new sheathed BOSCH 7V plugs. Are they ok for manual? How long should i have them on for? 15 secs is working great but is that too much for the plugs?
3) Is there a choke on this motor? I don't see anything on the throttle body.
4) The engine misses when starting cold. normal or am not glowing enough? (15 secs)
5) anything else i should know about this motor? ~200,000km runs great, i'm gonna adjust the valves and do the injectors when i have some time. also burns a little oil when started cold for a minute or 2. normal?

background:
always wanted a 4x4 Toyota diesel, a BJ60 actually, but around here they're always rusty and overpriced. 2 years ago I came across an '85 efi 4Runner in good shape for cheap, and I sprung on it. I was actually happy I ended up with the 4Runner- mini trucks make great rockcrawlers, the build up is cheaper than a croozer too.

But i always wanted efficient diesel power... i looked into the factory L series diesels... expensive, rare, timing belt, cracking heads, still pretty gutless... So I started looking at 3Bs they seemed cheaper and more readily available, and I always wanted one in a 60... the idea of a 3B in a mini truck has been debated before, too big, too heavy, too much work. I didn't care. Before I knew it I had a 3B sitting in the shop.

I started just before Christmas and finished (well started driving it again) about 2 weeks ago. Still need to finish the hood and put my winch back on.

How i got'r dun:
i'm forgetting everything at an alarming rate but basically i took a '85 Toyota Landcruiser 3.4L 4cyl diesel (3B, 12volt) and '83 cast iron bellhousing, ('85 bellhousing is aluminum) and hacked the tranny side of it off, milled it down to a total height of 6.285", and welded a .375" plate to the bellhousing. i had predrilled this plate to bolt to my '85s stock w56 tranny prior to welding. I used the W56 bellhousing as a drill jig for accuracey and to save time. I also took this opportunity to clock my entire drivetrain about 10 deg when welding the plate. i used the 3B clutch assembly, the disc is the same 21 spline as my W56 tranny, pilot bearing fit too. I used the 3B clutch fork and bearing, had to weld a nut to that .375" plate on the bellhousing for the fork ball-pivot to go into. for motor mounts i had to shorten one of the arms bolted to the block, so both sides were roughly equal. hacked the old mounts off the frame, made new frame brackets from 3.5x3.5" x .1875" tube. burned them on, finished deleting my rad support so i could fit the rad (stock 4runner for now, have custom 4 row for later), and that was basically it. no wiring except for a manual glow plug system, which is easy enough, and of course all the sending unit plugs were the same....

i guess this makes my truck a bastardized land croozer, model code BN65

[seapotato]

great job man !

I love it when people listen to "experts" saying it'll never work, then do it anyways....

not to mention the world of tranny tcase options this opens up....

you must provide pics.

I can have a go at a couple questions, I'll leave the hard ones tho , the miss could be an iffy glow plug or maybe just not enough glow all around, the smoke, unless it's truly gawdawful, is probably normal...( mine smoke too )



choke, well, there's a hand throttle, and on the edic motor, it does move the arm to "overinject' at startup, guess you could call that a choke?

now if only T.T. would do articles about this sorta thing instead of what folks from the southern states with deep pockets can buy, I'd actually re-subscribe....


cheers,

Yah now you see Huck, if you don't post some pictures and great detail about this swap the cruiser gods will curse you to a thousand years of bad luck. So don't piss the cruiser gods off, better get a write up on here for the sacrificial lamb.


That said.

No idea about getting the tach to work. I personally would get an aftermarket one and have it hook up to the alt for signal.

The relay you want to use is the primary one. It is the round heavy looking one. Yah it should have four wires. Two smaller ones are for the field, and large ones are for the glowplug flow.

Just wire your switch to the field Like this... fused power(small) to a switch. Then to the field coil of the relay. Other side of the field to ground. So when you turn on the switch it is energized. Use a fuse on the field wires, cause if the coil shorts to ground it will burn the wires if no fuse is present.

The main wires will go from the battery thru a large fuse, then to the main wires of the relay to the busbar on the glow plugs.
7v plugs are not ideal for manual. But don't glow over 15 seconds. With the 10.5 v I imagine you could glow for 30 -40 with out problems.

Use a push button switch only. No rocker. Unless the rocker is spring loaded to off. Otherwise you could for get it and then when driving cause it to either melt or burn out. Either way can't be good.

No choke. but on the BJ60's there is a hand throttle to set after it starts so that it can idle with out quiting. You need to be able to bump it up to 1k Rpm for idle when cold. Try fitting the 60 series on in there.

Yah if the idle is too low it will miss or improper detonate. Normal.Bring the idle up

A little smoke when cold is normal. Its not oil, its unburnt fuel in a cold engine. No problem. If your glow is heathy and it starts readily it is normal. Otherwise you could have a glowplug problem.

Ok now go make the cruise gods happy.

Congrates on a cool build. I want to see pics of this bellhousing work.

[huckthehaus]

Wow, thanks for the fast replies guys!

I didn't bother wiring the EDIC motor up. Just a cable to cut fuel and overinject. Choke=handthrottle, good to know. I need one anyways, i'll get on that.

The smoke is blue for about a minute when cold starting, pretty sure its oil because its blue, not black, but I've never owned an old diesel before. could be wrong.

As for the bellhousing, I wish I could have taken pics when it was out of the truck. But I can put the truck on the hoist for pics when i get a new camera.

everyone asked me why I didn't just use the stronger croozer drivetrain and rear axle, less hassle, and I had access to one. The answer is I've got dual case and lockers in the 4runner already, and have you compared prices on the mini truck and croozer aftermarkets?!

oh yeah, one more, i have mediocre heat. the heater outlet on the motor is the one 5/8" pipe on the driver side, right? and the returns are the 2 one the passenger side?

many thanks for the encouragement guys! write up coming soon!

[Rigpig]

Hey that's awesome! Been wanting to do this swap for some time, either Runner or minitruck, but i'm not home long enough to do anything about it or get sidetracked with other stuff. Like the "Potato" said, lets see some pics, and then turbo that thing.
Sawwweeetttt!
Cheers!
Dan

[HZJ60 Guy]

How'd you get this swap to work? Didnt it require an offset rear differential?

Good job.

[huckthehaus]

i was planning on a turbo before i did the swap, but this truck is a lot lighter than the croozers so i'm doing ok for power. besides, i don't think my stock tranny would like a turbo.

and i'm not running the whole croozer drivetrain. just the 3B to my stock W56 tranny through a custom bellhousing, to my dual stock tcases, stock rear axle

pics coming, need a new camera!

[Tapage]

Nice work dude .. this 4runner means nothing for this 3B engine .. !

Well the fuel is like oil. Fueloil as they call it for heating... cold it can look blueish white. Which is normal. A minute is a bit long. But we are not sure on the glowplugs/injectors.

Black is unburnt fuel underload when the engine is hot. Not cold.

I would not worry about the colour of it yet. Wait till the nozzles are serviced. Then do a compression check too.

A 3b though should not fog out the neighbourhood... so I hope thats not happening.

[knorrena]

Wow, thats just cool. Congrats. Say, do you have a part number for those glow plugs?

Karl

[huckthehaus]

Thanks for all the free answers guys!

not fogging out the neighbourhood, and the blue is probably for more like the first 30 seconds or less. i dunno why i said 2 minutes.

i'll look for the glow plug p/n tomorrow at work

anyways, this didn't happen overnight, it happened over 7 long days and sometimes nights in a 2 week bracket. i want to make a write up addressing every aspect of this swap to make it easier for other like minded nutbars in the future. i'll be honest, I did get some info from an Aussie named Jim who dropped a 3B in his Hilux, but he was having computer troubles while i was in the thick of it with my swap, so i did it my way. i'll probably end up doing the writeup first, pictures will follow when i can afford another camera.

[lumpy70]

Congrats! I wanted to do this exact swap but I wound up getting my 70 Series instead.

I'm happy that it's been done though,
Craig.

computer problems on a 3B?

[huckthehaus]

PC probs,

knorrena, i forgot that p/n today, i'll try for tomorrow

update:
i have since tied up all the loose ends but one:

i was having an issues with my hysteer draglink and tierod rubbing the oilpan while crawling. one time the draglink dented the pan in the middle of the ardbeg south trail in parry sound. the crank was hitting the oilpan and i was ****ting myself. i started solving that problem by making a custom bent draglink that drops around the oil pan, but i still need to make a custom tie rod and chop the oil pan (diff hits the corner of the sump in extreme articulation)

so thats a solid afternoon of work

everyone has said just lift the truck more and lower the bumpstops, and that would work great but i'm only running 33's. besides that's just a bandaid IMO.


I have put about 15,000km on the truck and it drives awesome. i also moved to north van from toronto a couple weeks ago, towing a 3,000 pound trailer. up to about edmonton this thing hauled ass. when i started getting into altitude towards jasper, i lost a ****load of power, and thats all it took to convince me i need to turbo this thing ASAP. so there is turbo in the works, i'm working in a diesel shop with tons of stock and a full shop, so it shouldn't be that hard.

i'll keep updates coming

cheers

i have a few questions if you don't mind sharing,

do you think there would be clearence issues with an IFS 4runner and a 3b?

what pilot bushing did you use?

did you only have to cut and weld the motor mount since you offset your drivetrain, or was that necessary either way?

same radiator as the 22re?

how about exhaust? same side as the 22re??

oh yea, awesome job man!

[Radd Cruisers]

Come on, a toyota without a 350 swap in trails???

LOLOLOLOLOLOL


PS, great swap.

We have a 1986 pickup in the shop getting a 3B and H55, tight sqeeze with the H55 espcially once the marling crawl box is installed.


Looking forward to the pictures...

now if only T.T. would do articles about this sorta thing instead of what folks from the southern states with deep pockets can buy, I'd actually re-subscribe....

If you saw the first pic you will se a SAS for this Runner so no IFS issues with the 3B.

[83 chif]

well i know he has an SAS, so he didn't have any ifs clearence issues, but i was asking to see if he thought there would be any clearence issues since he has seen a 3B in a 4runner's engine bay and i haven't.

[crushers]

what did you do for the added engine weight?
what rad did you use?
a 3B in a 4humper sounds cool, go buy a camera and get some pics up.

personally, i never thought it would work due to the height of the 3B and the weight issues...glad i was proven wrong...
