This is interesting...I was wondering how well QuickSteel would adhere to the manifold. Also there is already an open passage between cylinder '3 and 4' and '1 and 2' for the PCV. Maybe I will just leave those VTCS rod holes open then...and just plug the one to the outside with a bolt.http://www.mazdas247.com/forum/showthread.php?82884-How-To-VTCS-Removal-and-Porting/page9
Post #129. Open the PDF and all the info you'll need is in there.
The bar slides out, it's just a little sticky. Try wiggling while twisting with a pair of channel locks. Which holes do you mean? The one for the solenoid or the holes from the butterfly rod? I filled the rod holes with QuickSteel. I took my IM off about 3 months later to install my rear motor mount and noticed 3/4 of the QuickSteel plugs were gone. So skip that step. I removed the rest of the plugs and ran my motor like that for about a year without any issues.
I wouldn't recommend removing the ViCS, it's a good thing...VICS opens up a secondary short ram ports on the intake after about 5000 rpms...think VTEC (ala Honda)...hence more power at higher RPMs... Removal of VICS would kill your high power.Does anyone have a current write up for vics removal? That pdf is great for the vcts and porting everything out, but I can't even find pictures of the vics removal process
