Installation & Project Conversion Notes

• Shifter Positioning: Depending on your target chassis (e.g., standard vs. extended housing for SC300 or Supra MK4), minor R154 shifter tripod housing modifications may be required for perfect interior center console alignment.

• Wiring Setup: While the engine harness is complete and uncut, dropping this setup into a non-native USDM chassis will require a standalone patch harness or professional wiring integration to link the JDM engine plugs to your factory chassis dash cluster.

• Clutch & Flywheel: Includes factory-spec used clutch components (when available). However, installing a fresh heavy-duty performance clutch kit, rear main seal, and fresh transmission gear oil is highly recommended prior to dropping the unit in.

• Maintenance Recommendation: For peace of mind on high-performance builds, we recommend renewing the timing belt, water pump, valve cover gaskets, and spark plugs before final installation.
