6.5l chev diesel in a defender
Coming in late here but if you are still chasing info.....I have a 2001 110/defender/extreme with a 6.5L chevy diesel fitted by brunswick diesels in WA.Spectacular performance off road, different class altogether to the td5.I tow a 30ft fibreglass boat, guessing 3t, no problem, hardly know it's there.
Costs though and be prepared for some issues.
Overheating-still being sorted after 18 mnths but just about there.
Had to change tfr box over as was revving at about 3000rpm at highway speeds after conversion/it's either that or high speed diffs.
Gearbox now needs a rebuild-115k total/35k after the 6.5 went in...not happy.
Cost is out to about $25/$27k with the box rebuild.
But I love it......
