🧰 What to Look for When Buying a D16Y8 Engine

Before you click “buy,” here are essential checks:

1. Compression Test Results

Ask the seller for compression numbers. Healthy engines typically show:

• 180–210 psi across all cylinders

2. Mileage

Engines with lower mileage (under 100,000 miles) are usually a better bet.

3. Visual Inspection

• Check for oil leaks

• Look at spark plug condition

• Inspect coolant and oil for contamination

4. VIN Verification

Ensure it’s truly a D16Y8 engine. The engine block should be stamped with D16Y8 near the transmission mount.

5. ECU Compatibility

If you’re doing a swap, check if the ECU (typically P2P for D16Y8) is included or needs to be sourced separately.

🧾 Legal Considerations: Is the D16Y8 Swap Legal?

When doing an engine swap, consider emissions compliance, especially if you live in states like California.
