geoffbeaumont Posted December 9, 2005 Share Posted December 9, 2005 What engine would a K reg V8 discovery have? I think 3.5 and 3.9 where both available, but how do you tell the difference (this one doesn't have the capacity cast into the plenum like a range rover)?

imspanners Posted December 9, 2005 Share Posted December 9, 2005 I thought the carb version was 3.5 but EFi was 3.9....... But have been proved wrong on several occasions (usually by the wife)! Quote Link to comment Share on other sites More sharing options...
Matt Neale Posted December 9, 2005 Share Posted December 9, 2005 I thought the carb version was 3.5 but EFi was 3.9.......But have been proved wrong on several occasions (usually by the wife)! 1989 cars introduced with the carb 3.5. From 1990 ('91 model year) the EFi 3.5 was used (conicided with the introduction of the 5 door model and the alternative beige (instead of blue) interior. 1994 model year (from Sep 93 - Mar 94) introduced the 3.9 EFi 1995 model year (from Mar 94 on) was the facelift "300" version of the car - still with the 3.9 Efi If standard, a K plate should have the 3.5 Efi. Hope this helps. Matt Quote Link to comment Share on other sites More sharing options...

Matt Cheers - I had found a site selling engine ECUs that seemed to suggest there was an overlap (92-93) where both 3.5 and 3.9 were available in the Discovery, but everywhere else tallies with your version. Looks like it's a 3.5 I'm getting then - Robhybrid thought it was 3.9 but phoned me up today to say he had a nasty suspicion it was actually a 3.5. He's still doing me a huge favour so I'm not exactly complaining... Quote Link to comment Share on other sites More sharing options...

Damn, I made the fatal mistake of, thinking! I was sure, as the 3.9 was introduced around 1990 for RR, the Disco got it shortly after. Clearly not the case.

Rocket Posted January 20, 2006 Share Posted January 20, 2006 Just sold my K reg 3.5 Efi which was original. I think if it doesn't have 3.9 cast in the manifold cover its a fair bet its a 3.5. So whats the big deal whats wrong with a 3.5? you won't ever suffer from a cracked block and you'll hardly notice the power difference!
