My 76 914 passes Ca smog by a country mile. You must have a good CAT installed, use a universal one if necessary. I use a 924/944 unit since it is the same as 914.
I recommend verification of all items listed in the visual part of inspection. CAT, charcoal can, EGR, valve adjust + timing, and AIR pump. Check the under hood emissions sticker to see if any do not apply. May say NON-CAT
Do a sniffer pre-test off line not connected to DMV. Check measurements to see if it will pass. You do not want to fail on-line to DMV. The pre test usually will cost about $25

If high HC it is generally mixture related (rich) if high NOX, retard the timing for test. Once sorted, you should be able to pass every time thereafter provided it is in good tune. Like any car, any misfires will hurt your readings.
