The L18E was an engine that was used in the S11 Silvia. The L18E is an upgraded version of the L18S, but with electronic fuel injection rather than a carburetor, that produces at 6,200 rpm. The L18E was added in the S11 Silvia's 1976 upgrade for the "Type-LSE" trim level. Applications: 1976–1979 Nissan Silvia/Datsun 180SX (S10) L18T The L18T was basically the same as the L18 but had twin SU carbs, higher compression pistons, and lower volume combustion chambers. A high lift cam, bigger inlet valves and bigger exhaust valves were also fitted. It was installed into the 610-series Bluebird 180B SSS and UK market 910-U Bluebird 1.8 GL coupé. It produces . Also used in the Bluebird SSS Hardtop Coupé (910) for General LHD markets. L18P The L18P is the LPG version of the L18 engine. Applications: Datsun Bluebird 810 Datsun Bluebird 710 L20B The L20B is a with a bore and stroke of engine produced from 1974 through 1985. In US spec, it produces in 1974-75 form with of torque as installed in the Datsun 610 and in 1977-78 form with of torque as installed in the 200SX. The L20B engine introduced larger-diameter main bearings while retaining a fully counterweighted crankshaft. The forged U60 crankshaft also ushered in the use of a six-bolt flywheel boss. The block introduced a taller deck height to accommodate the longer stroke and connecting rods. This specification would also be used later in the Z20 and Z22 engine series. The bigger powerplant even helped spawn an important new offering from Datsun's competition department - Solex twin-choke carburetor kits- complete fuel systems that help produce nearly double the power from the ubiquitous L20B. The legendary robustness and nearly square configuration have made this engine a popular choice among tuners for turbocharging. The engine used a carburetor but switched to fuel injection (and round instead of square exhaust ports) in some non-USA markets in 1977. Carburetors were used in all US L20B applications for both cars and trucks. In the US, the L20B was used in six different model families -A10, 610, 710, S10, 620, and 720 models- making it the most versatile powerplant in the company's US history. To avoid confusion with the six-cylinder L20, Nissan designated this engine the L20B. 1974–1976 Datsun 610 1975–1977 Datsun 710 1975–1979 Datsun 620 1975–1979 Datsun 200SX (S10) 1977–1981 Datsun 200B 1978–1981 Datsun 510 1979.5–1980 Datsun 720 1981-198?
