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) and 2.2 (Z22) liters. 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.

See main article: Nissan Z Engine

Overview

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.
