Is there a difference between an SOHC Vtec solinoid and a B16A solinoid? I realize the bolt pattern may be different but im not sure. I was also wondering if maybe they flow differently?

 

think the DOHC are a little bigger, different mounting positions, Prolly same Deal, Whatcha getting at with this q?

 

I didn't know anything had to "flow" through a vtec solenoid.

 

WHen vtec activiates on my b16a its not that loud at full throttle, but if I creep up for 5k for vtec its louder then it is at WOT. I was wondering if maybe someone put a SOHC Vtec solinoid on my B16

 

there all the same.

NO they are not the same. The SOHC and DOHC solenoids are not interchangable.
They have different mounting holes and are different size wise also.

Also note, a JDM b16 solenoid is also bigger then a USDM b16 solenoid but are interchangable

 

No difference in vtec engagement at all?

 

The ecu controls vtec engagment not the solenoid
