If you check out Jackson's site the supercharged B18C1 produces 222hp, and the B18C5 makes only 215hp with the same supercharger. So even if you went with the Type R seems like it might be harder to make more power, unless that is, if you are going to stay N/A. If you ever want more power out of the Type R you have to de-engineer the perfect little Honda motor to make it ready for boost.
