just wondering, what's the difference between the two?

 

I think that V8 is the 3.9 and V8i is the 4.0. My '97 has the "i".

 

You have to be kidding!!!!!!!!!!!!!!!
The only thing the "i" designates is it is fuel injected, and they all are.
What year are you looking at?

 

my 94 with a 3.9 has v8i

 

mine is a 98 disco le v8i

 

Herb-remember that there is no such thing as a stupid question, only stupid answers. All cars sold in the US from the mid-80's on are fuel injected. I too have seen the rear door of a DI that only said V8 and did NOT have the "i" desingnation, so my answer was a shot in the dark.

 

what?!?! I've just been updated to junior member, AWESOME! lol

spike- ya, i figured it wouldn't hurt to ask, on the rave cd, i can't see the differece between v8i engines and the 4.0 v8. and even though my d1 says v8i on the back, it looks just like the engine shown for the 4.0 V8

 

All Rover V8's are the same, just different engine management systems. The DI's have the GEMS engine management and DII's have the BOSCH system. And I obviously know nothing about the "i" desigination.
In your RAVE CD you will also find the MPI engine (4 cylinder), diesel and the LPG engines. It makes for fun reading if you are a nerd and bored.

 

Your 98 is a 4.0 Gems engine.
