if it has a b18c5 in it its not a Honda Integra. If it was a real type R it would have a B18c in it.
If it truly does have a B18C5, then it's a US-spec car, or at least a US-spec engine.
As far as the turbo goes, I wouldn't turbo a Type R motor at all. Did you guys not look into this any? The B18C5 is meant to be a high-compression naturally-aspirated screamer, it's not really suited for turbo. If you do turbo then you're either going to need to drop the compression or tune it extremely well...
I agree that you shouldn't turbo a type r, mainly because its a disgrace to take honda's shining achievement of a 1.8 200hp motor. However aside from the pistons the motor is perfectly suited for a turbo set up thanks to the mild pnp job on the head and agressive cams.
