The Nissan SR18DE engine (or SR18 for short) appeared in 1992 and was an evolution of the SR18Di, with multipoint multipoint fuel injection instead of single injection. It is worth noting that the engines for the Nissan Pulsar and Sunny GTI have a high power (140 hp 6400 rpm) and a Compression ratio of 10 units. Structurally, the SR18DE is almost identical to the older “brother” SR20DE. The gas distribution mechanism for SR18DE engines is driven through a chain, there are hydraulic lifters (the engine does not need to adjust the valves), the ignition system is single-circuit.
SR family: SR16VE, SR18DE, SR20DE, SR20DET, SR20VE, SR20VET.

Disadvantages of the SR18DE engine
- Almost trouble-free motor, easily runs 300 – 400 thousand km without major repairs;
- Many owners are faced with floating revs due to failures of the idle speed controller and mass air flow sensor;
- Lubrication leaks are the crankshaft oil seal and the oil pressure sensor;
- The timing chain has a resource of 250,000 km, and it stretches to about this run;
- The use of poor-quality lubricant leads to clogging of channels and oil starvation.
