man its all up to you really. Go to some meets and talk to people that have k20 and type r swap, they'll give you all different kind of elements of what your searching for to help you decide. For me after talking to quite of few people with k-swap hatches, its fast, but having a B is can be quite as fast if cammed out to a k20a2 w/kpro. its all wat you wanna do to your "money pitted car"

K-swap is beasty. lots of time and lots of money.

that motor you got now is a great motor. K20 swaping in a civic? take caution, people will eye on it.

I still love my itr swap (jdm). But if your motor is good shape, ill buy your motor to help fund your "k-swap proj" . GL
