Specifications for RED Top SR20DET 180SX 91-93 and Silvia 91-93 Displacement: 1998cc (2.0 liter) Cam type: DOHC 16 valve, chain driven cam sprocketsBore and stroke: 86mm x 86mm Compression: 8.5 : 1Horsepower: 205ps at 6000rpm Torque: 203 ft/lbs at 4000rpmStock boost: 7 psi Throttle body bore: 60mmTurbo specs: Injector size: 370cc/min 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 bearingsPerformance: 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 Black Top S14 T28 VTCSilvia 95-98Horsepower: 220hp at 6000rpm Torque: 203 ft/lbs at 4800rpmTurbo specs:Compressor: T-28, 60 trim 60 mm BCI-1 compressor in T-04B housingTurbine: T-25, 62 trim 53.8mm 0.64 A/R turbine housing.Center Section: Ball BearingS14 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. S13 uses 'low port' intake design vs. 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 engine should produce 250-260 RWHP at safe boost.

Cast divider wall between turbine discharge and wastegate.Center Section: Ball BearingThis engine is expensive and hard to get. If you are on a tight budget, please consider other options.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.
