The Nissan Z Engine is readily available in both USA and Australia in early 1980s Datsuns and Nissans. They came in displacments of 1.8 (Z18), 2.0 (Z20), 2.2 (Z22) and 2.4 liters (Z24). The Z-series and L-series Engine are very closely related, it is possible to put a Z head on a L-series bottom end with the use of the Z24 front cover. Z18s are a top little motor and readily available in Australia. If price is no object, the CA18DET is a lighter and far more powerful engine. However, if you come across a Z18T and the price is right, it makes a little Datsun 1200 move out with style.

Z-series is the 2nd generation of the L-series engine. So oil pans and mounting is the same as fitting an L-series engine.
