I don't know man. Just depends on how you are going to use it and your personal preference. I've driven a Type-S and a Integra with a Type-R motor and I don't know what I like more. I love both the B and K series motors. If you are going to heavily modify your car, I think that the K series is surprising the hell out of people by how well it takes modificationsa and the power gains.

It's up to you.
