how do i go about getting my b16a motor to rev to 9000 or even 10000 daily with out fear of killing the motor.

aftermarket valvesprings and possibly retainers.

 

To be perfectly honest, there is no need to rev that high on a daily driven engine.

-full balancing/blueprinting
-shotpeened or aftermarket rods
-stronger valve springs/retainers
-stronger head bolts would be nice.
-cams that will actually make power up to 10k RPM
-port and polish would also help to make the power
-more I can't remember right now.

In short, it is very expensive and completely not worth it unless you are hellbent on having a high-rev engine or want the ultimate N/A build.

 

At that RPM, a dry-sump oiling system also would be a good idea. If you're hardcore about it- then :goodjob:- but be prepared to pay a fair piece.

Also, bear in mind, the gear ratios & final drive will need to be changed to suit the radically altered powerband....again another expense.
