Every 100 kcal of passion fruit brings 2.3 g of protein. On that measure it ranks 13th of the 71 fruits in this database and 675th of all 796 foods on the site. Measured by weight instead, its 2.2 g per 100 g ranks 11th in its group.
Only about 9% of the calories in passion fruit come from protein, so it is more of an energy food than a protein food. It is worth eating for other reasons; the protein it adds to a day is incidental.
Weight for weight, passion fruit has 3.1 g of protein for each gram of fat (2.2 g against 0.7 g per 100 g).
Set against avocado, another fruit entry in the database, a serving carries about 0.6 g more protein (avocado has 2 g per 1/2 fruit).
It is an incomplete protein on its own; pairing it with other plant foods across the day covers the full range of essential amino acids. The serving quoted here is measured by volume at 118 g, and it covers about 5% of the 50 g FDA Daily Value for protein.

How much protein do you get per 100 calories of passion fruit?
2.3 g. That figure divides its 2.2 g of protein per 100 g by its 97 kcal per 100 g, so it does not depend on serving size.
