The 2.2 S pistons may work with the CIS but not the E-cams!
You will get the higher compression ratio benefit from the pistons, The E-cams are too radical for the CIS, too much overlap and will result in poor drive quality. The CIS cams have much less overlap to prevent pulsation in the intake system which would upset the Air flow measuring system of the CIS.
The "low end torque" you so much enjoy is due to the CIS cams!
I don't think that the CIS cams will be a problem with interferance, but you should be sure to check the valve clearance on assembly, as this is a pretty unusual combination of components.
The only other caveat would be that the compression ratio may be too high especially with the milder cams. Race gas anyone?
Anyone else care to comment? What experience does anyone have with this combo? I bet few!
