Try this procedure:

SR20DET Camshaft Installation Procedure

Set crank to top dead center (TDC)…2nd mark from the left on the pulley. With the #1 cam lobes facing away from each other.
Remove tensioner.
Look at the front of the exhaust cam. You will see that there is a pin that locks the cam to the gear. You will also see a dot stamped into the cam gear at approximately 1 O’clock. This dot is used to mark tooth #1.
Starting from exhaust cam tooth #1 count (clockwise) the number of teeth until the top surface of the head. The head should be between 8 and 9 teeth.
Adjust cam position as necessary.
Find the DOT on intake cam. Once again this is tooth #1. Count COUNTER-clockwise to the top of the head. You should find that the top of the head should be between 4½ and 5½ teeth. Adjust as necessary.
Count the number of chain pins between the 2 dots across the top. You should count 20 pins.
Install tensioner. Rotate engine 2 full turns and slowly bring it back to TDC ( #1 lobes out)
Re-inspect cam position as listed above. Repeat if necessary.
Install CAS according to FSM procedure.
