I think 'Sunburst' will probably bloom the first season if it's growing vigorously. A friend of mine in Maryland tells me that it is the biggest monster of her Passifloras outside in the summer--and she grows a lot of plants. Proably It would behave similarly in your similar climate. I don't think it's nearly as strong of a grower out here, or at least it never has been for me.
I don't know if P. incarnata pollen would stimulate selfing of P. sanguinolenta, but it's certainly worth a try.
