Specifications for the Red Top SR20DET
(Found on the 91-93 180SX & Silvia)
Displacement: 1998cc (2.0 liter)

Cam Type: DOHC 16 valve, chain driven cam sprockets

Bore & Stroke 86mm x 86mm

Compression: 8.5:1

Horsepower: 205ps @ 6000rpm

Torque: 203 ft/lbs @ 4000rpm

Stock Boost: 7 psi

Throttle Body Bore: 60mm

Injector Size: 370cc/min

Turbo Specs:

Compressor: T-25, 60 trim 56mm BCI-1 compressor.

Turbine: T-25, 62 trim 53.8mm 0.64 A/R turbine housing.

Center Section: Journal bearings

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.

Specifications for the Black Top SR20DET
(Found on the 94-98 180SX)
Displacement: 1998cc (2.0 liter)

Cam Type: DOHC 16 valve, chain driven cam sprockets

Bore & Stroke: 86mm x 86mm

Compression: 8.5:1

Horsepower: 205hp @ 6000rpm

Torque: 203 ft/lbs @ 4000rpm

Stock Boost: 7 psi

Throttle Body Bore: 60mm

Injector Size: 370cc/min

Turbo Specs:

Compressor: T-25, 60 trim 56mm BCI-1 compressor.

Turbine: T-25, 62 trim 53.8mm 0.64 A/R turbine housing.

Center Section: Journal bearings

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.

Specifications for the S14 Black Top SR20DET with VTC
(Found on the 95-98 Silvia)
Horsepower: 220hp @ 6000rpm

Torque: 203 ft/lbs @ 4800rpm

Turbo Specs:

Compressor: T-28, 60 trim 60mm BCI-1 compressor in T-04B housing

Turbine: T-25, 62 trim 53.8mm 0.64 A/R turbine housing.

Center Section: Ball Bearing

S14 SR20DET's use a different ECU and harness, these are extremely expensive and hard to find.

Variable valve timing system and a different turbo are the significant changes from the S13 SR20DET engines.

The S13 uses a "low port" intake design vs. the S14 "high port" design.

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 stock engine should produce 250-260 RWHP at safe boost using stock turbo. Upgrading turbo, fuel and rest of need parts will yield 300-375.

Specifications for the S15 Black Top SR20DET
(Found on the 99+ Silvia)
Horsepower: 250ps @ 6000rpm

Transmission: 6 Speed, Close Ratio

Injector Size: 480cc/min

Turbo Specs:

Compressor: T-28, 60 trim 60 mm BCI-1 compressor in T-04B housing

Turbine: Inconel turbine wheel. Cast divider wall between turbine discharge and wastegate.

Center Section: Ball Bearing

This engine is expensive and hard to get. If you are on a tight budget, please consider other options as the money you save from buying this engine can be better used to build up a really nice red top.

Additions: 6 speed manual transmission. The 6 speed cannot be used on the S13 and S14 motors, and uses a different driveshaft. Speed sensor is located in the differential. The 6 speed is cool, but is not as strong as the 5 speed from the older cars. There is basically 6 gears inside the same housing that was designed to hold 5 gears. This makes the gears smaller and weaker, therby breaking more often.
