The compromises involved in fitting a turbo to a petrol make them less efficient.

Which is one of the reasons why a toyota prius isn't turbocharged but the diesel lupo which uses less fuel is.

50hp 4wd's. Plenty of them around. Landrover, Suzuki, Daihatsu etc. They surprised the world with where they went.

Yep , well , I 've got one of those 50hp engines in my rover and it went no where near as far as the 4.6 petrol engines went on the dunes

A standard 4BD1T puts out 86 kw/320 Nm at 3000 rpm and 1800 rpm respectively. A standard 3-53T industrial engine has output of 98 kw/423 Nm at 2500 rpm and 1600 rpm respectively. The little Detroit should have considerably more torque at clutch engagement, 800 rpm. This is a characteristic of Detroit two stroke diesels. The 4BD1T weighs 340 kgs. and according to Joe Hawkes, the little aluminium Detroit weighs not much over 200 kgs. Main problem would appear to be driveline strength in using the Detroit in a Land Rover.

Sounds like an interesting motor, are they hard to come by and very costly?

As for the driveline, i think a rat in a wheel used as a motor would probobly put stress on the stock rover driveline

Those are industrial engine specs (86/320).
My JDM 4BD1T was 103kw and 330Nm stock.
The stock fuel pump delivers enough to double those figures. Just needs more boost.

The BSFC figures show the detroit using around 20% more fuel than the average tdi (like the 4BD1T) to do the same job.
So fuel consumption would be on par with a nissan 4.2 diesel.

Those figures for the 4BD1T were taken from the Land Rover 110 Australian Supplement, what was fitted to the 6 x 6.

My experience with Detroits, mostly 8V92TA's at 435 hp was that they use about the same fuel as any comparable truck doing the same job. I had one out, (unapproved modification) at marine spec 545 hp @ 2300 pulling triples, gross >90 tonnes, that was a bit thirsty. But if you are not fed you won't work either. Detroits do the work easy and just about forever if you keep clean filters up to them. DDA had an oil analysis programme that would tell you if you needed to change oil. They maintained that changing oil for the sake of it was unecessary expense, "Change it when we tell you". They had a very low cost per mile due to low maintenance and longevity.

Yes, the standard landy fitment was an industrial motor. The truck motors have a higher state of tune.

What exactly does a 3 cyl detroit sound like? I have a mental soundtrack which is a cross between a perkins 3 cyl tractor engine and an electric hair-dryer.

I agree on un-necessary oil changes.

As Dougal said. Landie engines were the industrial 4BD1/T.

The civvie 110s had an uprated pump for more power - 99Bhp IRC compared to 85 for the stage1s and perenties. Not sure what the civvie 6x6s had, but as there were only a few sold it is a moot point.

Here is some good info on the 3/4-53T:

I must admit the 4-53T sounds good:

3-53T - hard to hear the engine over the screaming though:
