Thread: Isuzu 3.6 4bb1

I don't know much about them, but have heard they are not a bad motor, however have been known for breaking cranks in trucks. Hence the reason for the updated 3.6L (4BC1 or 4BE1 - can't remember which). But in a Land-Rover it should be fine.

No experience with them, but looking at the figures they are a higher speed and lighter weight engine than the 4BD1, suggesting they are a totally different design, although probably sharing a lot of common features but not parts. Coming from Isuzu I would expect they are a good design.

However, unless your S3 is a Stage 1 (with the LT95 box) or has a foreign gearbox as well as engine, I would be very surprised if the gearbox lasted long with a 3.6l, 4 cylinder diesel of any kind (it was designed for a maximum of 2.6l six cylinder petrol). Diesels are a lot harder on gearboxes than petrol engines, and fours are harder than sixes.

My Father has one and has just clocked 700000km.s with 7000k oil changes I know it is the 3.6 because I called him a dislexic old fart ,its 3.9 and he showed me it is 3.6l, aren't I a stupid boy

I have a 3.6L 4BE1 in my County. Good engine. Yes it is hard on the LT-95 (currently being rebuilt)

Owners of the 3.6 could verify, but o beleive they have the same powere output of the larger 3.9 ?

Model kW Nm
Isuzu 4BE1 74 242 @ 3500 rpm 3.6L
Isuzu 4BD1 66 245 @ 3200 rpm 3.9L
Rover 3.5 litre V8 - 83-86 84 249
TDi200 79 256
TDi300 83 265
Toyota 1HZ NAD 96 285

Isuzu 4BD1T 90 314

There is some confusion here between the 4BB1 and the 4BE1 - they are a very different engine.

The 4BB1 produced 72BHP (54kw) in most configurations, and was not a very high revving engine. It also has a bore/stroke of 102/110mm whereas the 4BE1 is 105/105mm. 4BB1 is 3595cm³, 4BE1 - 3636cm³.

The 4BE1 was the first of the more modern higher revving high output isuzu diesels.

hay ! have a 4bb1 that was a hydraulic power supply , ran for ever still runs , it use to power one of our directional drills . dont drill any more . was going to put it in a front end loader , cant find a #2 sae bellhousing , now am going to put it in a ford truck ?? mite work for around the farm !! those engines are built solid and with maintenance will out last me !!
