In 1987 Barilla returned to single-seaters and raced in the Japanese Formula 3000 Championship, before returning to Minardi in 1989 for a test. This test gave him the chance to replace Pierluigi Martini at Suzuka that year and afterwards was signed to drive for the team in 1990. Barilla wasn't quick enough to qualify regularly and was replaced before the end of the year by Gianni Morbidelli.
