They were 2 petrol engines, early in the game, the smaller one shared the 4 cylinder OHV layout of the diesel version, it was 2.3litre with five main bearings.
The other was he 3.5 V8. ( With the LT95 Same as the Perentie ( Sorry Thread now as Perentie in it )
Then the 2.5L Petrol came available in 1986, replacing the 2.3 unit.
Like Garry Said the smaller one not sold here, and I don't think the 2.5 was?
Gary did we get the 2.3L Diesel?
