He is doing a frame off resto on a 1971 FJ40 and he is going to run a NV4500 and stock axles transfer case and gears with 35's and ARB's F/R he is going to run a engine that has both good fuel milege and power he will be doing a bit of rock crawling and mudding and various other trails. he is really conidering a diesel?

4.3 chev vortec
carburated chev 305
chev 350 LT1 or EFI
6.2L or 6.5L diesel
5.9L cummins diesel

or which engine do u think that he should run? :confused:

i think he should run a gas turbine from a chinook helicopter:D

He will think about the gas turbine but i dunno if that will fit so what ever u guys think will be good say it?

LOL LOL LOL ! :beer: :beer: :smokin: :D :D

Run a Chevy V8 and be done with it.

1st choice would be the 350 TBI or Vortec, second would be the 4.3 vortec, third would be the 6.2, and last, and least would be a carburated 305!

Jeff

whats the 5.9L cummins from?
whats some basic specs on it?

whats some basic specs on it?

Lots of torque, no Horse power, small, but very loud!

Jeff

Does anybody else have a sugestion, does anybody know the specs on the 3B, on size, HP, Torque, how many cykinders is it? what 5 speed bolts up to it, can a NV4500, and what kind of performance can u get out of it with a turbo? will the turbo be able to go under water if it gets hot and then wet?

I just traded away my 75 FJ40 to a friend... I am keeping the engine tranny Tcase and axles... he has a Dana 60, and HD70
and a cummins turbo diesel with a big inline pump and big injectors!!! these engines can easily put down over 800 LB/FT at the rear wheels. I would go with the cummins 5.9. it is a way better engine than any mere v8 and they came with NV4500s bolted to them!

there should be no question, go with the 5.9!!!

I always regreted my v8 swap. the six cyl is a better engine for 4 wheeling, and a diesel is only better.

If you mean 3B as in stock Toyota engine.

Not in the same league as the engines you mentioned!
4cylinder, 3.5Litre, NUGGET!

I got one in my cruiser. It goes alright, definately no rocketship.
It chugs along off road. I would not go putting one into a cruiser though. Too many other engines that will outperform it for less money.

I think with low gearing it is a good, not excellent, engine for off road.

You don't need any more opinions, Jeff nailed it. Notice the complete ommission of the cummins.

Does anyone have the weight of the cummins 5.9? :question:

Funny, I was reading the "Land Cruiser Portfolio 1956-1987" (collection of articles), and noticed one Australian (??) writers comments that "the 4.2 liter engine is too large, wish they had fitted a more economical 2.0 liter engine!". :eek:

So I guess it is all about what YOUR needs are. Admitted many swaps are based on "what is lying around the place". My 3FE maybe retrofitted to a tractor! Well, too much $$$ in it to toss out, might as well find a use for it. Good Ballast. :D

There's a lot of kewl factor in building/installing a non-standard swap into your Cruiser....those cummins Diesels and whatnots that people are playing with sure are fun to see.

However, they are not fun when something goes wrong....

Chevy 350s are the cheapest to rebuild, are available everywhere, are easy to find parts for, the aftermarket loves them, adapters are made all over the place, and they perform well in a Cruiser to boot. TBI is nice for it's simplicity, but a good ol' quadrajet will suffice almost as well.

I can rebuild my 350 for $156 and a weekends worth of work. It just don't get no easier or cheaper than that. I've got almost 4 years on the rebuild now, and if you don't count the fact that I subbed it at 5 days old, it runs great. (now, it includes the non-factory "foot-massage" feature...)

why not a carb 350? of course...when i go to a v8...im not dikin around with carburators...but i see a lot of carbed 350s as easy swaps...:rasta:

The EFI V6s 4.3s are getting to be pretty popular in Idaho. By years end we will probably have a half dozen of them running around. Mid to High 20s for gas mileage is the reason why. 700r4s and 420s and 465s to three speed cases is what they are running. The motors are fairly cheap as the hot rodders don't go for them. I think the Cumins would be cool. But it is way overkill for a 40 and you are looking at big bucks just for a coolness factor. 350s are sort of the standard. The 6.2s and 6.5s are a motor that you either love or hate and it all depends on the year and phase of moon as to whether you get a good one or a bad one. In the summer of 96, I worked at a Chevy dealer we had 13 sold while I worked there, 12 of them came back with injector pump problems. I think there are fixes for this. Good luck in whatever you decide it is a lot of work.

Hey, I LIKE my carbed 305!

And the quadrajunk carb works surprisingly well off-road.. it really only acts up on me on a downhill, which doesn't bother me much at all.

I think that the 5.9 is over kill, and seems like it will destroy the cruizer, He likes 6.2's but they have to be turboed, and with some luck maybe he can steel his dads :) And the 3B might be interesting if it can be souped up n such, do u guys thik its a good swap? and he wants gas milege so the carbed 350's and 305's are out I think, sorry guys, And I think that the vortec 4.3 is a bad moter because I have heard that it gets problems after 200 000km's, This leaves the 6.2, 6.5, 3B, or EFI chev 350, Are there any other engines you would recommend? does a chev 6.2 or 6.5 bolt up to a NV4500? And thanx for the help and advice u guys are giving, It helps A LOT.

I've read that the cummins 6bt=5.9? is very heavy about 1000 empty. I think the cummins 4bt witch is a 6bt minus 2 cylinders is a better choice because it weighs less. I have a na 3B and it's great offroad, but a little bit slow on the highway.

for all around driveability, ease of installation and maintenance as well as performance on and off the trail i'd go with the 350 tbi for sure. plenty of power for a cruiser, cheap to install, parts a plenty, virtually no maintenance (except for oil changes) lots of after market support, tons of conversion parts available,...

and on top of that, 1000s of peolpe have done that conversion into a lot of different rigs so finding somebody who actually knows how to do it does not take a brainiac!:rasta:

So does anyone know wut a 4 cylinder cummins come in? and what year it was produced? and the HP and torque? and does a Nv4500 bolt up? and i was also wondering what kind of milege does a TBI chev 350 get in a FJ40 running stock gears and 35's? And is there anyone running 6.2's and 6.5's and what do u think about the performance of them. Thanx for all your help.:cool:

dont know what all bolts to a 4b cummins, but you will typically find them in forklifts, grade tractors and misc. construction/industrial type machines. they put out desent torque numbers, but horsepower is in the samurai range, i think around 80HP. but really thats fine if your not doing much high speed driving, look into AA for adaptors i'm sure they have stuff for it.

Here is some information I have save from different posts about diesels...
<hr>
The Isuzu swap has become a favorite in Venezuela, especially in the 60 and 75 series, but also in a handful of earlier 80 series. The preferred engine is the 4-cylinder 4BD1-T, it's got the right dimensions, decent HP and torque specs and best of all, has a GM-pattern bellhousing that would open up a slew of different tranny options. Like Charlie mentionts, gearing is critical with a diesel engine, you want to stay within the effective powerband, remember that diesel engines in general reach their top HP and TQ ratings at lower RPM's than petrol engines.

Personally, I don't think the 3B is a good candidate for an engine swap *unless* you come across a cheap one (and I do mean, cheap). Yes, it's a bombproof industrial design, but it's also a dog, it's underpowered for a hard-core wheeling application unless you run an aftermarket turbo with it, and even then, for a serious wheeling truck that won't see a lot of highway miles but will most likely be trailered to the trails, you're better off (economically and technically) running a petrol engine, and in the US at least, *nothing gets better than a SBC*.

I really like Toyota diesel engines, in particular the LASER 6-cylinder series (1HZ, 1HD-T, 1HD-FT and 1HD-FTE), but the sheer cost of the powerplant and ancillaries makes it a practical conversion only if you plan to drive a LOT of miles on your Cruiser. For example, my friend Jeff put a 1HD-T in his US-spec FJ60, mated to an H55F and combined with a FF rear axle. He's put a ton of miles on his truck, driving from NorCAL to Tucson, AZ several times a year and back. In his case, the cost of the conversion (close to $10K, with him doing all the work) can be amortized by the fuel savings, but if you don't put a lot of miles every year, that kind of money can buy a LOT of gasoline.

The Isuzu 4BD1-T is an excellent turbo diesel engine, commonly found in the US on Isuzu NPR cab-over medium cargo trucks and their GM counterparts. Plenty of engines floating around, and they've been retrofitted onto several different models of Land Cruisers, so we know it fits!

HTH,

So with a vortec chev 350 and NV4500 and stock gears and 35's can u get over 20MPG on the freeway, or what milege? and what kind of city milege do u get, If its over 20MPG he is going to go for the tried tested and true SBC.
