Nissan Silvia S13 SR20DET Blacktop 2.0L Turbo Engine & 5 Speed Manual RWD Transmission Swap JDM

Experience the legendary power of the iconic "Blacktop" with this JDM Nissan Silvia S13 SR20DET Engine and 5-Speed Manual RWD Transmission Swap. Widely regarded as the holy grail of drift and street-tuning platforms, the S13 Blacktop SR20DET is renowned for its immense aftermarket support, responsiveness, and bulletproof factory internal architecture. Unlike the later Redtop variant, this Blacktop unit features refined intake and fuel system configurations that provide superior throttle response and high-RPM stability. Sourced directly from low-mileage Japanese donor vehicles, this complete package includes the long-block, manual 5-speed RWD gearbox, and essential ancillaries—offering the perfect, turn-key foundation for your Silvia, 180SX, or S-chassis drift build.

Installation & Conversion Notes

• Fuel System: To maintain the factory performance profile of the Blacktop SR20DET, it is mandatory to use 93+ octane premium gasoline. We recommend installing a high-flow fuel pump (e.g., Walbro 255) to ensure consistent fuel delivery under boost.

• Cooling: The S13 platform benefits significantly from an upgraded high-capacity radiator and a dedicated front-mount intercooler (FMIC) kit to manage intake temperatures during sustained high-load driving.

• Maintenance: Prior to the initial startup, install a fresh water pump, new timing chain tensioner (highly recommended for SR20 longevity), and high-quality 10W-40 full-synthetic oil.

• Wiring: As this is a JDM-spec engine, we recommend identifying your chassis's harness pinout before final integration to ensure seamless signal transmission to your gauges and fuel pump relay.
