You wont get more power and torque to weight ratio than the Xtrail and especially from the RD28. The things are generally as slow as buggery. The RD28 are prone to head issues just as much if not more than ZD30s blowing up. ZD30 IMO are a good enough engine and the reason so many RD28s were sold is because they were the cheapest turbo diesel in the new shape Patrol (GU). Nissan didn't stick with the RD28 engine as it is a tractor engine and went to the ZD30 which they have had for now over 10 years, thats longer than the RD28 has been in.
Where do you plan on driving? TB45s on gas can be cheap and if you don't mind a smaller km range this would be my option. If not save your pennies and buy a ZD30, I bought my mint condition 2000 ZD30 ST with 20,000km on the new engine for $17,000 two years ago and have now seen them for $15,000 and under.
I do believe that the ZD30s are considerably better on fuel as well, thats from my mate that had both so driving styles are negligible.
