I agree with Laurie.

Depends on whether you want a BMW straight 6 or Peugeot bent 6?

As far as power goes, I previously had 94 LSE with upgraded TD5- basically same/similar power and torque to L322 TD6, but the TD6 seems to keep torque longer through rev range. I guess those extra 400cc 's help?
I have not compared with TDv6.
