I think you can find your engine capacity in your car rego details. I think all D2's in Australia can with 4.0 from the factory. In the States they can with the 4.6 as standard.

Tow something,,,,

By simply typing a random engine number prefix in the "search" box I have found this:

That's factory fitment. Then there are the replacement engines.....

9.35:1 is HC

Cheers and happy searching

If the engine fitted is as built it will be a 4.0.

As noted by others, all Australian spec D2 V8s were 4.0 engines.

Where did you do the search?? My engine number is 56D64882a??

Red book is your freind...
Disco 2 V8 Eng No : 55 or 56D####A (55 / 56 depending on MY)
4.6lt range Rover...48D00021A
If you have the books, the eng no (found on the block left side of engine) should match with that written in the book. As should the VIN.

Hello again. For those of you interested there is a web site Clifton Scientific Text Services, the Netherlands that can do a calculation on your VIN# and give you all the info you need to know about the code.
