i have a b18a1 and im looking to do some head work does anybody have any knowledge on extrude hon porting??? prices maybe??

 

Contact ExtrudeHone directly. They have a facility in Irwin, PA and another on the West/left coast. The process does wonders when done right. If you plan to run in SCCA ITA or Honda Challenge the porting can only extend 1" into the head and manifold. (In those cases it is to get them aligned and matched.)

 

A Three-angle valve job and extrude honed intake manifold can really make a difference in airflow through the motor. I would suggest contacting a well known servicing company like the one above or perhaps one in your area to get details. You may have to mail the part to the company for service if it is too far away.

 

Thanks Guys
