  A good example to start with is the Nissan VG30DETT engine. It belongs to the VG engine family, displaces 30 deciliters (3.0 liters), and the feature letters describe an engine with dual overhead camshafts, electronic port fuel injection and two turbochargers.
  The next example is the Nissan VQ35DE engine. It belongs to the VQ engine family and displaces 35 deciliters (3.5 liters). The feature letters describe an engine with dual overhead camshafts and electronic port fuel injection, but leaves off any power adder descriptors because it is a naturally aspirated engine. The (single) turbocharged version of the VQ displaces 30 deciliters (3.0 liters) and is logically called the VQ30DET.
  Not all features are necessarily described in the name. For example, the SR20VE engine has dual overhead camshafts, but the variable valve lift design of the camshafts takes precedence in the naming scheme even though the "V" feature designation doesn't necessarily describe a DOHC arrangement. Many standard DOHC Nissan engines featured Variable Valve Timing, such as the VG30DETT, and as such do not use the "V" designation. The "V" designation is applied only if the engine has variable valve lift.
