    3.5 injected or carbie

    I have just bought 2 Rangie's an 85 model and a 86 one, with the idea to make one out of the 2. The 86 has got the nod and work has begun, all rust cut out and new floor welded in. Nearly at the stage of the interior being placed back in.
    The question i have is, What engine do i use, the injected one (have not heard great news about lucas injection) or the carby powered one also what gearbox a 4 speed auto or a 5 speed manual.
    It will be mainly used for weekend 4x4 trips not excessive and towing the camping trailer.
    If anyone could provide any advice it would be greatly appreciated.

    i have never had an injection RR so cant comment too much but from what I have heard some people prefer the carbys as they might be "bush fixable" whereas the electronics would probably not be but are less prone to faults, (never had a carby issue though since mine where rebuilt).
    I like the strommy carbys because they are very set-up and forget, unlike othere carbys.
    As for which engine you could use either engine with either carbs or injection so just go for the one with less K's or the one that appears to have been looked after better.
    Gearbox? auto or manual i always think is personal preference my daily driver is auto but for off road i prefer the control of a manual, (thats just my opinion though).

    Not much for you to go on but at least its a start.

    Go the auto - the ZF is a strong box and is arguably more wife friendly than the manual. For towing, particularly off the mark, I prefer the auto, however without lockup in 3rd you may find yourself wishing for the manual at cruising speed. Since your going with the '86, this should also save a lot of work. Donk wise, the EFI version when new, had something like 165hp, the carb version was around 130hp. Dispite the prince of darkness label, the lucas flapper EFI ECU is actually a bosh system made under license by lucas and can be very reliable in good condition. However you may well find yourself replacing components in the long run, so if budget is a real issue the carbs maybe a cheaper option in the long run.

    go the carbys, well thats my opinion after my flapper style efi has just cost me a grand to fix, got the news today, new flapper A.F.M reco ecu and hours of labour chasing faults, if i could change to carbie and still have it road worthy i would, prince of darknes sucks, i have heard the hot wire efi systme found on 89 models and up is a lot better. and been told she's still not running real sweet but hoping injector cleaner works to help the last bit

    The EFI is actually Bosch with Lucas stickers. I've had no problems at all with my flapper injection system since i owned the vehicle....11 year now.
    The problems with carby systems in particular multi carb systems is finding someone with the skill to overhaul and tune them. They will all be worn rather badly by now.

    Can't tell you what you should do but I can tell you my experiences; my first RR was a 1984 model, had it for about 5 years. The carbies were the worst part of it, requiring frequent attention. The stromberg carbies, due to their system of damping the airflow rather than boosting the fuel flow with an accelerator pump, have an annoying lag when you put the foot down- you get used to it but when you again drive something with instant response you sure notice the difference. The diaphragms can perish or split causing problems of their own.
    My 2nd RR was a 1988 EFI model that I have now owned for over 11 years. The EFI system has been far-and-away more reliable than the carbies ever were. problems with LPG that cause backfires will damage the flapper-type AFM, this is an LPG problem rather than an EFI problem and is the most common issue that people seem to have with them. I had zero problems with it in 8 years, then had some issues after installing a 4.4 and getting the system tuned to run it.
    I was reluctant to go to an auto 4wd after having manuals previously, however soon found that the auto is fantastic for mountain trails, especially climbing. It does not have the engine-braking of the manual; low 1st in the auto is a slightly higher gear than low 2nd in the manual. I now have a low-stall torque convertor in the vehicle and this dramatically improved engine braking.
    Hope these coments are of some use.
    Pete
