need some help identifying a turbine housing
 

I'll post pics if you think it will help, but I don't believe it will. It's an S5 exhaust housing that's been bored out for a larger turbine wheel, which I don't have. Hell, I don't even remember how I came in to possession of this thing...

Anyways, the exducer measures approximately 65.3 mm. I think it may have been a bnr hybrid, but who knows. Does anyone know what that size exducer bore equates to?

(I accidentally posted this in the 3rd gen section too... :blush: )

Sounds like what I have done before .We used ser 5 exhaust housings and fitted GT35 cores in them

Seems like it would be a p-trim wheel?
They have a 64.6mm exducer, which leaves about .35mm of clearance on each side of the wheel.
