I see where you're coming from, no argument there. The only thing I'm not seeing is why you think the whole engine is crap just because of a coolant issue... Land Rover has used the same engine for decades, well before the DII was ever around and it never had as bad of head gasket issues until the switch to Dexcool. I agree that it is a problem, but to say the whole engine should be scrapped just because of that is a little harsh imo.

 

I'm in need of anew engine... got a 4.0... and i do think it's a piece of ****! 180 hp on a 6,000 truck?? I mean c'mon! "Oh it's sufficient for off-road use"... blah blah blah! Great!!! I can go up a trail but the friggin thing down shifts on a 3 degree incline just to maintain my cruise speed of 45 MPH!! Due to the fact that i drive mine ON road as well I need more HP. Gaskets are leaking like a mother. Oil is dripping. I don't need 400 hp but at least 250 would be good... or a 4.6 but $4500 remanned for only 40 more horses? y'know i used to have an explorer with a v6 and that gey little engin had to try so hard to push that truck that the v8 version gets better gas mileage!!! my point? It should be obvious... under powered is ****... so is 500 hp... but the truck which is amazing, should have sufficient power. so what can i do? a guy at roversnorth sent me to this guy who remans rover motors told me the 4.6 still isn't good enough. he said drop an LS1 motor in there... but how much would that cost and is it possible? What about that buick motor? The rover motor is unimpressive when compared to alot of other great motors. So what is another great motor i can thro in there?????

 

So sell it and buy a subaru seriously it's a moot point. No other non rover engines are going to bolt in, you will have to do a fair bit of fabrication and probably end up with too much weight, not worth it. Or if you have 6K burning a hole in your pocket:

Too much weight, won't work with the ECU, tranny would also have to be changed along with the t/case, both diffs to handle the extra power and a whole list of stuff that makes it way too expensive to do.

 

the diffs have to be changed for an extra 70hp?? Why does the Tcase have to go? Cant the DS be changed to accommodate length difference?

 

the diffs are the weak point in the driveline now.

 

yea, that makes sense. It would be nice like the days of old, where if you wanted to mix things up, it would be a matter of fitting and mounting. I have an old early second gen camaro, so that's what im use to working on. Plus, it would be a nightmare trying to get the sensors and such to work.

 

I know this might sound like heresy here, but I'm still a jeeper at heart.

What about a Jeep engine and tranny in a Disco? If you could adapt the Rover T-case to a Jeep AW4 tranny, and stroke a Jeep 4.0L to a 4.6, you would have a pretty bullet proof drive train, that puts out the same, or a little better power numbers. Using the Jeep engine and tranny computers would negate the need to adapt the Rover computers to work.

It's probably entirely too much money and work to be worthwhile, but it would definitely be interesting to see it done.
