$4000 plus shipping and handling

think your better off getting a regular h22 and spending the other $2-3k on say....supercharger

the main differences between the regular h22 and the type-s are only a couple things.

Cams
Pistons
Intake Manifold

Theres about a 2000 dollar difference between the regular h22 and the type-s, and with that money you can build a much better motor with more power.
