The B Series engine from Honda consist of a Dual Overhead Cam Cylinder Head, and a 4 Cylinder Short Block.  with Vetc and Non Vtec engines, there are many combinations that can be created.  The heads are different from one another, and both are useful in different applications.  Many aftermarket options available, contact us to get started.  We do not stock Vtec Heads, and must be supplied for the project.   Pricing below is Vtec, which is great for those High RPM builds.  We can modify pin sizes to fit different OEM pistons for those custom builds.
