Installation & Maintenance Notes

• Maintenance Recommendation: To ensure the longevity of your new power plant, we strongly recommend performing a "pre-install refresh" including: a new OEM water pump, high-quality spark plugs, a fresh timing cover seal, and a new clutch/flywheel assembly suited to your driving style.

• Fluid System Care: Prior to startup, flush the manual transmission with high-quality 75W-90 GL-4 gear oil and fill the engine with full-synthetic 0W-20 or 5W-30 engine oil (depending on your climate and driving intensity).

• ECU Integration: As this is a JDM-spec engine assembly, verify your vehicle's current ECU/PCM software compatibility. Depending on your region, you may need a professional re-flash or calibration to optimize the D-4S injection timing for your specific fuel quality.

• Professional Tip: When installing the engine/transmission combo, ensure the driveshaft angle is properly set and the shifter linkage is adjusted for the specific gear gate alignment of your center console trim.
