Lots of choices with these motors. I thought my stock 2,2 T motor was a sweet running motor.
Yea the E cams will bump up the horse power some. Perhaps +10. I imagine if that is the only mod made the Zeniths would be fine if opened up a few mm. PMOs probably would be an over kill if the cam is the only mod. Since you are in there E pistons would be a nice addition, as would be larger cylinders. Then top it off with some head work and you would have a screamer. Don't over look K&N air cleaners and a sport muffler. It all adds up.

E cams will make a noticable difference. If you can increase the compression...another step in the right direction. 2.2 is a short stroke. Anything to lighten the valve train will help it rev.

You’ll need E or S pistons for the valve clearance. Also need the extra compression ratio with the more aggressive cam timing to get a decent dynamic compression ratio.
There are larger ventures available for the Zeniths. 30mm or 32 would be good along with jetting changes. Open the Intake ports up if they are smaller than 32mm.

You could do what I'm doing 2.2S crank, 2.2S p's & c's with DRC mod-solex cams and S cylinder heads. Should be a fun little motor.
