  • Performance:
    The stock turbo will be safe to 13-15 psi. After that, the turbo is past its efficiency range, and power increases will fall off and are not worth the risk of turbo damage. The engine should produce 230-250 RWHP at safe boost.

 

A 1.8 L (1838 cc) DOHC engine. It produces 125 PS (92 kW) @6000 rpm and 156 nm @4800 rpm. This engine came with Multi Point Fuel Injection System ECCS (Electronic Concentrated Control System).


The SR20Di is a 2.0 L (1998 cc) DOHC engine. It produces 122 PS (89 kW). Bore and stroke are 86 mm (3.4 in) and 86 mm (3.4 in). Similar to the 1.8 liter version except for bigger displacement with a throttle body injection system.


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 169 Horsepower (104 to 126 Kw) from the factory.


The SR20DET S13 was produced for the 1994-1998 Nissan models.  The SR20DET S13 is one of the more popular used Nissan engines sought out by tuners today.  The trick is always finding a decent used JDM motor in great condition with good compression test results.  Many JDM engine importers travel directly to Japan and test each engine.


The 2.0 L SR20VE has Nissan's Neo VVL variable valve timing with lift control. It produces 190 PS (139 kW) @7000 rpm and 144 ft.lbf (196 Nm) @6000 rpm and later (2001-2003) 205 PS (150 kw) @7200 rpm and 206 nm @5200 rpm. It does not have 20 valves as is sometimes stated.

 


The 2.0 L (1998 cc) SR20VET was the first turbocharged engine from Nissan with variable timing and lift control. It produces 280 PS (206 kW) @ 6400rpm and 309 nm @ 3200rpm. This motor was only produced in the Japanese market and is very hard to find.
