The Nissan L series of automobile engines ranges from 1.6 L to 2.8 L in both straight-4 and straight-6 configurations and were produced from 1968 through 1980 (4cly.), and 1970 through 1984 (6 cyl.) It has a 2-valve per cylinder SOHC Non-Crossflow design. The L13, L16, and L18 were all offered as factory engines in 510s from 1968 through 1972. The 6 cylinder motors are quite a bit harder to fit into the engine bay because of their additional length.
The L16 is a 1.6 L (1595 cc) engine produced from 1968 through 1973. It came with the small port 210 head casting believed to have been designed for the smaller L13 motor which was never available on North American 510s
The L18 is a 1.8 L (1770 cc) engine produced from 1972 through 1974. It was available in US domestic vehicles for the 1973 and 1974 model year. Also, many of these engines were imported from Japan during the 80's and sold as replacements for domestic L16s. These imports usually had the desirable closed chamber W-53 head with larger ports
The L20B is a 2 L (1952 cc) carburetor engine produced from 1974 through 1980. The B designation is to differentiate it from the L20A, an inline six cylinder 2 liter engine by Nissan not available in North America. Early L20Bs had U-67 square port exhaust heads, later were W-58 'smog' heads with steel liners in round exhaust ports. The '79 200sx had the closed chamber W-58 head with liners.
