Trents are Rolls Royce, it is the Trent 900 details are
Engine certification was achieved on schedule in October 2004 through the
new European Aviation Safety Agency. Even though it will operate initially
at a maximum take-off thrust of 70,000lb, the Trent 900 is cleared at an
80,000lb rating, allowing margin for future growth. It reached thrusts in
excess of 90,000lb during early test bed running.

With a fan diameter of 116 inches, the Trent 900 is physically the largest
engine ever built by Rolls-Royce. It is also the world's cleanest large
turbofan engine, measured by emissions per pound of thrust.

no idea about a design change but I read somewhere that the engines were
Trents. Can't remember if those are GE or Rolls. I know they
are not Lycomings or Continentals.
