Too small of a charger to use for twins. HX55's come with 64mm or 67mm intake wheels. Exhaust exducer is usually 77mm. They will work as a single with the right exhaust housing.

An s400 exhaust housing will work- it needs to be off of one with a 74mm wheel, the housing will have to be machined to fit the 55. A 1.0 housing seems to work decent. You will need a t-3 with adapter or a t-4 pedistal.
