The Nissan SR20DE engine is one of the most successful engines made by Nissan and is used in over 15 Nissan models. It first appeared in Nissan’s Bluebird in October 1989, and has migrated into many other models of cars since then, from sports cars, to family saloons and even people movers.

The breakdown of the engine code is as follows:Pedrito Carson Wallace

* SR – Engine Code

There was also a LEV-version with 125 hp (93 kW) and 132 hp (98 kW). It was built from 1990 through 2002. The bore and stroke are both 86 mm (3.4 in). It uses SEFI.

SR20DET

The SR20DET is a turbocharged and intercooled version of the SR20DE, initially producing 205 PS (151 kW) in the S13 Nissan Silvia and 180SX. The second generation in the S14 Silvia produced 220 PS (166 kW) through the use of Nissan’s VTC variable valve timing and a ball bearing turbocharger. The final S15 Silvia version produced 250 PS (187 kW) @6400 rpm and 275 N·m (203 ft·lbf) @4800 rpm with an improved Inconel impeller wheel for its turbocharger. The SR20DET has become a common engine swap for a wide spectrum of cars ranging from Nissan Sentras (using FWD versions of the SR engine), to Datsun 510s (Datsun 1600) because of its compact size, RWD format, and its oem turbo.
