Well, I'll take it over any of LR's mechanical diesel offerings any day. A TDV6/8 of course is a different story...
But really, it fits, the rest of the components can handle it, and it's adequate power for what the average LR driver wants to do with it.
Stuffing in a high-revving Jap lump just seems like a horrible idea, I drive like a retard and am not that high up in the rev range all that much. Do you really need 9k RPM in an LR?
An LS or something is nice, but really not a much more modern design. They have more power, yes, but also drink quite a bit, and parts availability outside the US is horrendous!
