im after any info if anyone has put one of these engines in to there patrol or landcruiser. i just picked up a copy of the "just 4x4s outdoors mag. and it has an add in it advertising a engine swap for the 4bta engine to replace the 2h in a 60 series.
basically im after a conversion for my 2.8 gu which is getting a bit old and will be needing a rebuild in the near future, and am looking at different options. ive thrown e 6.5 chev idea cost to much for old technology and is restricted with the indirect injection. am likening the 4.2 td idea but am looking in to all ideas. if anyone knows much about this engine or conversion any help would be appreciated.
im a apprentice fitter so i will be able to do most the labor my self

What's a dodge ram jet? Ram jet is the trade name for GM performance parts open loop efi crate motors.
I've looked long and hard at putting a 4BT in a my Gwagen and they look pretty good. I'd have no issue that they'd do the business power wise. They are tall and heavy though. Bear in mind, adapting a overdrive gearbox isn't the easiest as all the options are for North american boxes - NV4500 etc.
I'd probably run one with a T400 and 3.9 diffs with 35's to avoid the expense of an OD gearbox. That combination looked ok, but only with the higher speed governor mod.
Go for it I don't want to be the only person who thinks this is a good idea (like most of my other ideas)

The Isuzu 4BD1T is a very similar engine, but with the intake and exhaust on opposite sides and a higher rev range.
The Isuzu's rev to 3600, the cummins to around 2500 stock but to 3200 with a little tinkering.
Both will happily push a fullsize 4wd along at 100km/h at 1800rpm all day.
I think the current best for power from a 4BT is about 450hp, but they're doing a lot of work to get that.

I guess the big choice issue comes down to gearbox between the 4BD1 and the 4BT.
Obviously rover boxes are fairly easy behind the 4BD1, but other boxes and especially autos will be harder. The adapter for 4BD1 to t700 offered in the US looks both expensive and complex to me.

There are guys in the US who've used the isuzudieselswapper adaptor to a GM pattern, then another adaptor from GM to toyota pattern.
Seems to work for them. But it's getting a little complex.
If goin auto, marks do the T700R adapter to the nissan transfer, I dont know to much about the rest.
I did do a little reserch into the 4.8 isuzu Turbo Deisel (from the NQR if iI remember right) It would of mated to the manuel (TD42, TB series) fairly easily.
Isuzu use the same splines as nissan manuels, I have an nissan/isuzu clutch combo in mu gq ute.
The 4.8 isuzu did have a 4500rpm redline also so same rev range as td42, stock power was 115hp 480Nm from memory.
I'm not sure if any of this was useful but I am interested in the conversion also.

Yeah, the ease of finding GM auto to most transfer adapters readily makes the 4BT/GM auto look appealing plus, automotive 4BT's normally come with T400s already behind them, from frito-lay vans.
Also, auto/turbodiesel combinations are much nicer to drive than manuals.

i have been reading alot of info on the 4bt swaps site, and with the new cummins 6.5L engine the 6bt (5.9L) has decreased in value 10 fold, and now wondering how hard it would be to put one into a gq, guessing im gonna have the same problems that adam would, it seems like a very practical swap, and would produce a great deal of torque yet still remain reasonably economical.

They are very, very noisy, very very big and very very heavy. (1000lb) You're also going to want a VERY torque capable gearbox, which is going to have to mate to a transfer. Even the factory dodge autos don't last. you're going to be looking NV5600 or 4L80E + an adaptable transfer. $$$$$$$$$$
I'd love a 6BTA, but think the're not really very practical to be honest.

Rogers car....What's a dodge ram jet
on topic i saw a site where a guy had put a 6bt into a 40 series in the states, definately a big heavy motor, had to beef up the front end and then change where the radiator/fan fitted - it's pretty long and yea like steve said about 1000lb in weight.
Had one at work a while ago powering a mobile vacuum pump, really has that TRUCK idle to it, makes a td42 sound like an rb30!! although it was mounted on a skid (no enclosure)
There are no stupid questions, but there are a LOT of inquisitive idiots
looked very seriously into putting one in the gu and they arent heaps lobger than a td42, weight isnt a huge issue, nothing the right set of springs and shocks wouldnt fix, the main problems were find a suitable gearbox to run behind it, casue no doubt most people on here would be like me and starting hotting it up and the torque these thing are capable of producing is down right insane!!!!
Even a built 4l80e would be pushing s*&t up hill tho handle it so you would need a fatory dodge box, the there transfer cases runs down the left of the car not right like ours, so custom diff or aftermarket transfer
and then i started thinkng about diffs, as good as gu diffs are im not rally sure the would hande the copious amounts of torque a cummins could thro at them
I signed up on lots of yanky forums, found cheap motors, asked lots of questions and its definatley doable but by crickey your wallet would want to be rather bloddy fat!!!!!!
If any one does tackle it, my advise, get a 1ST gen 12v 5.9 (88-91 ish), mechanical pump motors like our td's, no electrcal crap to worry about or if your not afraid of electrical work a 2nd gen 12v( they run a better pump and you can buy a sigma after market pump-full billet body, mega power potential and huge huge huge dollars) ,
Most guys are pulling the later 24v out and slamming in 12v's in the hunt for the big hp numbers because they reckon there a better motor
Thats my 2c worth

Must be another reason the 4BT's are going up in price.

The Isuzu 6BD1 is a more civilised alternative to the cummins 6BT. Commonly found in buses and Isuzu's in this part of the world.
I believe the facctory dodge auto is weaker than a 4L80E. Lots of breakages once 6BT's are tuned.
If you think more weight is just "fixed" by springs and shocks you're not ready for a 6BT conversion. (roughly) doubling the weight of the motor is going to play havoc with balance, braking, weight distribution, front axle housing and shaft strength....

about 3 years ago ther was a early 90's 75 series cruiser for sale in Darwin, it was a 6 wheeler [lazy] and it had a 6bd1 [ isuzu] in it.
about 5 years ago when my mate was looking at doing a engine swap [75 series also] he was tossing up between a 6.5 chev diesel and a 6bd1.
he ended up going with the chev [big mistake] only because he trusted the mob doing the chev conversion for him [another big mistake].
next time i speak to him i'll ask who was doing the 6bd1 conversion and see what the deal is.

1000lbs = 446.5kgs
If I'm not mistaken doesn't that put this inline with the TD42 at something like 450kgs?

think the cummins is a bit heavier than that but basically thats what i was thinking, i mean were talking a 4.2 against a 5.9, not a 16l c16 cummins!!! they actually are not that much bigger than our motors, ill try an d dig up the specs i got, there a bit longer but not heapsclm434 wrote:1000lbs = 446.5kgs

The biggest weight gain would come from using the allison autos they come with, they are absolutley massive, if and only if you could make it fit our auto or 5 sp (with out busting to a 1000 bits) it will save heaps
And yeah, a good set of springs would do it, and any one dumb enough to do a conversion like that and not do a brake up grade upgrade shouldnt be doing it, hell im going for bigger brakes on my gu and its only a 4.2, stock s pittiful
