    2.5L NA diesel.

    What kind of mileage are you getting?

    City/hwy.

    Thank you

    In a soft top 88 using a GPS for speed and distance I've averaged 27.3 mpg
    since I put the engine in a year ago this summer. Can't tell you city hgwy mileage because I have never done a full tank of in town only driving. When I went into the woods last July I got over 30. The worst tank was 25.

      In my heavy 109 station wagon, I was getting about 20mpg before the engine rebuild, now I'm getting 24mpg since the rebuild. Same disclaimer as Jim--This is a combination of city and highway driving.

      In another month or so, I'll be able to give you the MPG rating for a 109 regular with a pickup cab.

        just makes you think that if a 40 year old lump of minimal technology with the aerodynamics of a barn and one of the simplest engines in existence can get that kind of mileage why are modern ecomony cars today not getting 100 mpg.

          Put all the modern (emissions etc) crap in and on a vintage LR engine and try to drive it at modern highway speeds and it wouldn't fare so well either. When you consider the HP and torque modern engines make vs. their displacement it isn't that surprising IMHO.

            I have been getting pretty much 27 Imp. mpg (22.4 US mpg) per tank since installing the 2.5 in my 88 soft top this summer. And that is all city driving. Screams a bit too loud for my liking at higher speeds so will stay off the highways until I get a Roverdrive. Several thousand kms on it now and still lovin it.

                Just gotta check the usual places...LRX.com, ebay, daz.org, etc
                Mike at Brittanica Restorations has one listed here.

                I got mine from our hosts several years back.

                  I am thinking about putting the 2.5 NA (sitting in the garage right now) into my 109 petrol (need to increase the range). How did you setup the return line at the tank?
                  My 109 tank does not have any blank plate like the 88...

                  Thanks

                    Thank you.

                    Wow! The MPG of the 2.5NA is a huge improvement over the 2.25 petrol...

                      It was easy--I got a fuel uplift tube from the scratch and dent pile at Rovers North and cut off the pickup tube so that it was an inch long. Then I carefully drilled a hole in the tank, catching the debris through the sender hole Then mounted the shortened uplift tube to the tank. Next I went to Home Depot and got an adapter and a hose barb and ran a hose from here to the fuel spill rail.

                      It's probably easier if I just show you the pic. The return line is the one on the lower right:

                        I see. Looks like your pick up tube is in the sender unit then.

                        Here is what I've got right now with the gasoline tank. I probably can add the return line in the red area...

                        Thanks.

                          Don't know if you've priced one of those uplift (draw) tubes lately, but it might be easier/cheaper to figure out if one of the later fuel senders with the integrated draw tubes will work for you. Then you can draw off the sender and return through your current uplift tube.

                          Another, more economical choice would be to use AN fittings. You could use a 90-degree bulkhead connector to go through the fuel tank, then just adapat it to a hose barb fitting to the other end. http://www.anplumbing.com/shop/.

                            For the $ most people ask for a 2.5NA you might as well get a 200TDI or 200DI from Rover Resource or someone like that.

                              x2. Better motor as well. 2.5's are not know for their speed.

                              I would do a 200tdi and spend the money to get e Variable turbo for it. COuple UK vendors have them now and they are supposed to be awesome...
