Driving along a freeway in Australia, unless in the N.T, speed is pegged typically at 100kph. To maintain this speed on level road in a normal family sized car requires from memory 40HP or there abouts. So a little bit more in a LR or RR.

Torque is what is really important, much more so that outright HP, so how much is necessary? The standard factory 4.6 produced in the order of 400Nm, and with a different cam such as a high torque edition the torque will come in sooner and improve low and mid range pull.

A 5.7 or 6 litre Chev will deliver more torque, but is it really a benefit? A Range Rover already can go where most would rather not take it, so what will be the advantage? Pushing through sand at a higher speed for example with a full load will only overload the drivetrain resulting in increased wear and reduced longevity...and more cost.

If ever I've learnt something, its that people become biased, they argue why you shouldn't do something, that they've never tried, then use reasons as to why not, because theirs is good enough, again not having tried

Your ****ty rover motor has no timing control, no knock retard, no closed loop, **** ports, slipped liners, cracked blocks etc, they are far from a great thing........yep you can fit aftermarket management, then you loose decent cold start, all the correct idle ups for A/C, roll to stop etc and your fuel economy is CRAP either way:D

But that's you, not everyone

Your car suits YOUR purpose

Most mechanics I know, wouldn't be capable of fitting a commy V6 in anything but a commodore:(

Right again, its easier.......for a less rewarding result:)

Hello rovercare,

I do like my Rover, having been driving it for 25 years, and I have every intention of keeping it forever. One day I would like to buy a LR too, and I might consider replacing the engine, but only with a top hatted 4.6. I see no point really in creating a bitza.

You like what you do and there is nothing wrong in that..for you. Others disagree and there is nothing wrong with that either.

Ron.

If you ever meet someone who's life dream is a go fast land rover... smack 'em in the head for me, please...

I've watched all the episodes of Fantasy Island and have never seen the little bloke say anything about a 9 sec landy. :)

Well I will probably go for a 4.6 next time, but I am still worried about its longevity.
When considering the cost of a 4.6 , you should also add on the very expensive rockers, shafts, head recon etc. Also a 3.9 injection cannot really run a 4.6 without at least a chip at $1000+
So a 4.6 will run to say 4900+ 1000 for heads +1000 for chip. About 7K excluding labour.

A used 4.9 injection (VS VT) should be buyable under 3K and that should include the ECU and wiring. Adaptor to ZF and interfaces for ECU, simulators for GM BCM etc about 2K from Marks.
I would not buy a second hand 4.6 under any circumstances.
