Whats the technical name for my motor?

I have a 93 GTS. It has a 2.2 16 Valve. Im trying to time it with a Haynes Celica repair manual. Seems to be a problem. This motor only has ONE cam gear. wtf. I gotten 3 different opinions, time it 90 degrees from the valve cover for TDC.
Should i be looking in a camry/corolla repar manual?


Any Help would be wonderful
