No it remains the same size. The inside inlet fan may be bigger but the overall diameter and length remains the same. From wiki:But isnt the inlet Fan diameter bigger in F-414 and dimensions bigger, so weight reduction target may not be that severe.
The F414 fan is larger than that of the F404, but smaller than the F412 fan.[4] The larger fan increases the engine airflow by 16%, is 5 inches (13 cm) longer, and increased diameter from 28 inches (71 cm) to 31 inches (79 cm). To keep the F414 in the same envelope, or space occupied in the airframe, as the F404, the afterburner section was shortened by 4 in (10 cm) and the combustor shortened by 1 in (2.5 cm). Also changed from the F404 is the construction of the first three stages of the high-pressure compressor which are blisks rather than separate discs and dovetailed blades, saving 50 pounds (23 kg) in weight.
