For all who dont know....

OK HERE AR THE SPECS ON THE SR20DET (s14)

Horsepower: 220hp at 6000rpm Torque: 203 ft/lbs at 4800rpm

Turbo specs:

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

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

Center Section: Ball Bearing

Variable valve timing system and a different turbo are the significant changes from the S13 SR20DET engines. S14 uses 'low port' intake design vs. S13 '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.

Required Parts for the install:

Engine, transmission, alternator, starter, power steering pump, Crank Angle Sensor, ECU, harness, MAFS, Power Transistor / Ignitor Chip.

Fitment:

Fits into US 240SX S13 chassis with no modifications. Uses the US 240SX of the host chassis driveshaft and differential. Uses the standard downpipe and catalytic converter with the 240SX catback exhaust.

Fits into US 240SX S14 chassis with no modifications.


RB20DET specs:
No. and arrangement of cylinders = 6, in-line, vertical
Combustion chamber type = Hemi-spherical
Valve arrangement = Overhead valve type
Camshaft arrangement = Double Overhead Camshaft
Total displacement cc = 1998cc
Bore x Stroke mm = 78.0 x 69.7
Compression = 8.5:1
Bhp = 214bhp at 6600rpm at flywheel
transmission loss = 38bhp
