It is pretty easy man.
The latest models are the NS and the RR models. The NS is the "short rod" and the RR is the "long stroke". There are two types of pistons, CNC and microcast. Then you have 3 and 5 ports, the 5 ports have more horsepower and RPM.
Thats all you need to know about Novas.
If you then start talking REX and TOP plus IDM etc then it is more complex, but they basically are the same base motor.
