Aluminum alloy block and head with steel alloy sleeves.  Distributor-less, crank angle sensor activated ignition, direct fire coil packs. Stock SR's come with an internal wastegate, a knock sensor, a side mounted intercooler and a bypass valve that is routed back into the intake after the MAF before the turbo. Stock turbo outlet is 1 7/8 inches, inlet and throttle body are ~2 1/2 inches.  

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.

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 and S14 chassis with no modifications to engine mounts or transmission mounts.  Uses the host chassis driveshaft and differential. Uses the standard turbo SR downpipe and stock catalytic converter location with the 240SX catback exhaust.   89-90 chassis will need tachometer or cluster, power steering lines and reservoir from 91-94 chassis.
