They cost a lot compared to the C1, yes. But worth it, definitely. But horsepower isn't the only thing that makes up a motor. All the stuff that the C5 comes with from the factory is worth all the money if you add it up. So what if it doesn't put out monster loads of horsepower. Matched with the suspension setups of the Type-R family, they're great factory road/backroad cruisers.

What it really comes down to is what the OP wants to do. If you're going boost, B18C1 all the way. If NA, you could do C1 as well, but if you got money, get the C5. [/$0.02]
