It features an aluminum head and aluminum block with steel sleeves in selected models, the average JDM engines are cast iron blocks and steel-aluminum alloy heads, this type of block was sometimes used to save manufacturing costs on lower trim cars. DOHC 4-valve design, with some versions incorporating variable valve timing. The engine was used in many small to medium Nissan vehicles, including high-performance turbocharged variants. It was designed by Nissan as a replacement for the earlier CA series of engines. Power output shown is JIS Net PS or ECE Net kilowatts unless otherwise indicated.

This is an example of cast iron block, in the pursuit of a more economical type of trim Nissan put this blocks on some cars like the Primera.

In regard to the Nissan Primera vehicles this system was only used on the P10 generation and due to the low overall power this engine option was dropped on the next generation, this engine was never been installed on the US counterpart the Infiniti G20.

SR20DE and SR20De

The Nissan SR20DE engine is used in over 15 Nissan models. It first appeared in October 1989 and has been gradually phased out since the introduction of the QR (low-emissions) engine family. The SR20DE carried nominal power ratings between 140 to 145 Horsepower (104 to 108 Kw) from the factory. The design was very responsive to aftermarket improvements and became a favorite among compact sports car enthusiasts during its operational life especially as it revved very high. (redline @ 7500rpm)

The breakdown of the engine code is as follows:

• SR - Engine Code
• 20 - 2.0 Litres
• D - Dual Overhead Cam
• E - Electronic Fuel Injection
• e - SR20DE LEV-version
• RR - Roller Rocker motor

This engine has the following specs according to a SAE paper released in 1991

It was used in the following vehicles:

SR20DET

S13 Silvia SR20DET NS Mounting, Coil On Plug (custom yellow paint)

U13 Bluebird SR20DET EW Mounting, Distributor

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 VCT variable Cam 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. It is also very popular in the U.S. as an engine swap for the S13/S14 due to its factory JDM application in the Silvia.

The Nissan Pulsar GTI-R version was developed as a World Rally Championship homologation engine. It received Quad throttle body and a Garrett T28 turbocharger, larger injectors, as well as a large top-mount intercooler.
