    Upgrade Range Rover Engine - 2 door Classic

    Hi Guys,

    I'm New to the forums! Hi!

    I own a 2 door range rover, owned it since I was 16! It was my daily driver, it has dual fuel, and the 3.5 carby engine and 4 speed manual. Runs dual fuel too. (on LPG its running a little rough, think the carbies need a look at..)

    It barely gets driven these days, but still goes really well. Having to drive it around recently as my daily was out of action, I now remember... this thing is so slow... I hate feeling like a need to thrash it just to keep up with traffic... It bugs me!

    Anyhow, was researching and the p38 4.6 engine seems to be a nice easy change over (not by me..)

    Some tips would be great.
    Who in Melbourne would you recommend to carry out the job?
    Anyone recently done this?
    Probably keep the stromberg carbs, can I keep the lpg?
    What realistic cost? Go for 2nd hand or rebuilt? Rebuilt would cost much more, but less risky...

    Should I consider any brake upgrade after this?

    I'll upload some pics...

    attached below... this was back in 2002.. haven't got a recent pic... nothing has changed much, removed the super heavy roof rack. Paint work needs a little work.. need to redo the headlining now. I would LOVE to reupholster the seats

    None of these modifications are possible you will have to sell the vehicle to me...

    Seriously i would leave the 3.5 in there. The vehicle is worth more as original. A good rebuild with hi compression pistons a decent camshaft and proper carby tuning, lose some of the weight and it will transform the vehicle. Ditch the gas too.

    this engine was rebuilt 12 years back, but car has probably only done less than 30,000k's since then... nothing wrong with the engine... the right thing to do is to leave it... but I don't plan on selling it, so I can leave the original engine in storage.... I would love to be able to curise around effortlessly...

    what is approx cost of cam and for someone to install? Will I notice much difference?

    A well running 3.5 is a better engine. Except for the lack of cubes they are superior.

    The easiest way to tackle this is to buy a 4.6 high compression long engine and all your ancilliaries will bolt onto it. IIRC you will need to grind away a little edge of the block casting where the oil pump housing on the timing cover interferes with it or something similar but it was a long time ago that i did it so my memory is hazy.

    Yes you can use your flywheel and clutch etc and enjoy all the extra torque... 😎

    The old 3.5 Classic I used to tow a sweeper with, had been re-built and 'cammed' for towing up to 80 km/h, and was respectably quick across the traffic lights and beyond, - died after 90km/h

    With the plant unhitched, it just... fleeewww

    Seriously, I'd suggest getting the most out of the (relatively robust) 3.5 block, convert to high compression... then decide if you need more 'cubes'.

    Really have you thought of what extra torque will do to 40 year old drivetrain parts?

    The poor old transfer case will probably die first and the whole LT95 will then need a rebuild which is expensive.

    My tip would be to get a wrecker discovery 3.9 V8 5 speed manual and use the engine and transmission from it, although you will have to modify the transmission tunnel. You could probably get a low mileage one for a grand or two as they are written of with just cosmetic damage these days.

    Much of the OLD feeling of a 3.5 2 door comes from the old LT95. I used to skin my knuckles on the aircon on changes to third. I remember discussing the options with SWMBO and to my surprise she said get a newer one which I did. She hated the gearchange and the Fairey overdrive which had to be changed down at every slight rise.

    It would be a nice car and not cost a lot to do.

    Regards Philip A

    I have a 3.9 low compression R380 disco engine in my 4door running on gas. It's way faster and has a lot more power and torque than than my old 1985 Range Rover. It had a strong carby 3.5 high compression petrol only V8 and went nicely....

    The injected 3.9, even though it's a low compression engine running on LPG ... would leave it for dead in every aspect though.
