Diesel or Gas

[1Bad4Runner]

Ok, I am in a predicament.. I have a couple options. I know where there is a 3.4 with no computer or wiring harness and I also know where there is a 84 (I think) Landcruiser with a 4cyl diesel in it, which is a better choice?   

[hudlenutz]

Which diesel is it?  Is it efi or mechanical fuel pump?  How many miles?

What engine was orginally in the vehicle?

[1Bad4Runner]

It is a 3B 3.4 liter Diesel, assuming it is mechanical... the mileage is fairly low I think. My 4Runner has a 3.0 in it and the engine in the cruiser is original.

Deisel is way more unique. May have better MPG too.

[hudlenutz]

I'd go diesel.  I think it'd be easier to hook up than the wireless 5vz, and much cooler.  Buy both, sell the 3.4 for a profit to fund the diesel conversion.  Most likely transmission would be the H55F.  I'm not sure on the compatibility with the mini truck trannies.

It'd be sweet to turbo the 3B too.

from brian894x4.com...

All B series engines are 4 cylinder, 4 cycle diesel engines. Most were manufactured by Hino
Industries, a sub-contractor of Toyota. Some were manufactured by Daihatsu, identified by the letter
"D" on the timing cover. Apparently Hino engines similar to the B and 3B are used to run the
refrigeration units on some tractor-trailers.   Most diesels in Japan and Canada are 24V (and
therefore meet NATO military specs), with the exception of Canadian BJ60s and 1985 BJ70s which
are 12V. In Europe, all diesels before 1984 are 24V, and most B series after 1984 are 24V as well.
Australian diesels are 12V.

The most widely used engine from this series. It apparently came
in at least three versions with slightly different stats. One
difference is that until 1986, it came with an inline injection
pump, and then after 1986 it had a rotary injection pump. In
Japan the 3B was used from 1981 to 1990, but Canada stopped
importing vehicles with this engine in 1987. The 3B is found in
the BJ42, BJ43, BJ45, BJ60, BJ70, BJ73, and BJ75. This engine
is a favourite to turbo because like most turbo engines, it has oil
nozzles that spray the bottoms of the pistons.

· displacement: 3431 cc
· injection: indirect
· horsepower: 90, 93 or 98 at 3500 rpm
· torque: 159, 163, or 167 ft-lbs at 2200 rpm
· valves: 8 ohv
· bore: 102 mm
· stroke: 105 mm
· compression ratio: 20:1

A turbo kit for the 3B...

A concept 3B which claims 220hp, 300ft-lb and 30 mpg

This 3B's starting to sound pretty good... wait a minute... YOU should run the 5vz and sell ME the 3B   

[1Bad4Runner]

I like the sound of that, not I wonder if it is worth $800?

Also I could put a Supra turbo on it and it would be much cheaper!

[kneedownnate]

So on the 3.4 with no harness and computer, any idea how much they'd get rid of it for?  I was just talkin to a friend today about fabbin up an intake manifold for one and runnin a carb.  Could make for a very simple (or atleast more simple) swap in a first gen.

[1Bad4Runner]

The guy wants $500 for the motor, tranny, and t-case. But I will not go carb again. 

[kneedownnate]

We are talkin 3.4 v6 right?  Seems like a fairly good deal if you get the trans too.

[1Bad4Runner]

Yes, I know it is a good deal... but Its missing the wiring harness and computer, which will probobly cost me like $800 or something.
I have been looking around and found non yet.

[rockscrambler]

just my personal opinion I would perfer and am looking for a diesel to put in the rockscrambler but I have no ideal about toytas and diesels . I just prefer diesels!

[1Bad4Runner]

I'm with you there, especially the 30mpg. I love diesels, they work awsome.

I'm which one is beter, but I think I will be going diesel just to be different! 

[kneedownnate]

You're in canada right?  I've seen on toyotadieselmadness.com where a bunch of people are sayin that you're lucky if you get 23mpg in a 4by diesel, and one who's gettin about 15-18 mpg.  Then again, I've talked to one guy with an 82 toy diesel 2wd that said he consistently gets 48mpg, so it really varies.  Either way, with the popularity of bio diesel and the process refinement that goes along with it, I'd gladly snap up a toy diesel if I found one.

[rockscrambler]

I think MrW said something about that bio diesel or maybe it was someone else around here  but I do know the MAMMOTH is diesel so you might ask him

[kneedownnate]

I know nissan had diesel pickups back when they were called datsun, but the other day I saw a hardbody king cab 4by at the grocery store and it sounded dead on like a mercedes diesel.  Wierd, maybe it came down from canada or something.

[1Bad4Runner]

...Wierd, maybe it came down from canada or something.

Lol, whats that supposed to mean? 

[kneedownnate]

You guys get all the cool stuff, like toyota diesels and straight axles up till 95, lwb sammys and on

[1Bad4Runner]

Sweet, where do I find a 95 straight axle? lol, I've never seen one... but we do have a lot of ramdom crap around here!

Be sure you check into the gearing you will need. Diesel engines run at lower RPM than gas engines.  The LC transmission may be geared right for you to run down the road, or you may have to step up you differentials too. See what differential gear ratio the LC has. Surprises at the end of big projects always suck.

[kneedownnate]

All over canada man, I've seen a bunch of em for sale.  Not sure how much I'd worry about the gearing issue, I've seen an 82 toy diesel tach that redlined at 5k rpm, but the LC engine could have a lower rpm.  Maybe do some research and see what redline is on it.

[1Bad4Runner]

I can probobly just go and check what the truck redlines at, it only 45 minutes away. I have 5.29 gears, So I hope thats fine... but If not, I'll have to go a step down.

[rockscrambler]

A friend of mine from when I was in the national guard bought one of the military diesel blazers very low geared 55mph and your near red line and he added and overdrive he got out of some old car and says he can make 80 easy now before he even comes near red line

just a thought

[1Bad4Runner]

Yea, maybe a nv5600 or something... if they are compatible.

[kneedownnate]

Weren't those military blazers really low geared though?  My friend bought an 83 diesel blazer a while back and I was really surprised that it didn't seem to be reving too high on the highway.  Maybe his was running 3:07s or something high like that, and military ones are running 4:56 or ??

[rockscrambler]

not sure but I know he said that this was the only thing he could do to get it up to freeway speed and he tried everything else and nothing worked but he wasn't a mechanically inclined person so    what his everything was .

[1Bad4Runner]

Yea, the military ones ran 4.56's I'm pretty sure, but they are also big engines in them to. I may have to come down to 4.88 to get it back to normal... even though I am running 36" tires.

The LC only has a 4 speed too 

[hudlenutz]

The peak horsepower for the 3B was listed at 3500, which isn't that much different than a 22r, so I wouldn't worry too much about the gearing until you drive the vehicle with the new engine.  If the gears are too low, you can always underdrive it with bigger tires.

Yea, I like your thinking!

[rockscrambler]

my friend> is an idiot and I'm > an even bigger idiot for repeating the drivel that comes out of his mouth . I called the chief at my old guard unit who is the one that did the install of the overdrive on his blazer and he said he installed an overdrive and 1bad4runner is the winner of the million doll hair question he also changed out his rear end and installed an OX Locker the one with the shift cable

Huh, how much do I win! Where can I pick it up?!
