Honda G engine
Honda G engine
The Honda G series engine is an inline 5 cylinder gasoline engine, originally used in the 1992 Acura Vigor, Honda Rafaga, Honda Ascot and Honda Inspire. It carried over to the Vigor's successor the 2.5TL, which ran from 1995-1998.
Some people colloquially refer to an F-Series block (found in Accords) with an H-Series head (found in Preludes) as a "G series" engine. This combination of an Accord bottom end with a Prelude head has nothing in common with the actual G-series engine. The engine is longitudinally mounted and resembles an F-Series single cam engine (found in early Accords) with an extra cylinder on it and a shorter stroke.
