To demonstrate the jet engine it engineered for the Boeing 787, Rolls-Royce has built a scale replica of the engine entirely out of Lego blocks. The Lego engine will go on display July 14 and 15 at the Fanborough International Airshow outside of London.

The real version of the engine, called the Trent 1000, has 66 turbine blades that provide 800 horse power each. When flying, the tips of the blades whirl at twice the speed of sound, according to Rolls-Royce. Trent 1000s are in service in 10 Boeing 787 Dreamliners owned by the Japanese airline ANA.

The plastic, snap-in building block version of the engine has more than 160 of the same components as its real-life inspiration. It took 152,455 Legos and 1,280 hours to build, employing four people for eight weeks. It’s half the size of the real thing, so it’s about seven feet long and five feet wide. “It made me realize how amazing the actual Trent 1000 is,” Ed Diment of Bright Bricks, a Lego-sculpture company that worked with Rolls-Royce to build the engine, said in a statement.
