8. Things to Look for When Buying a BNR34 Engine

Checklist Before Buying:

Engine tag and serial number (should begin with RB26)
Compression test results
Turbo condition (check shaft play)
Oil leak inspection
Engine mileage and history
Original ECU included?
Wiring harness intact?

Consider using a mechanic or engine expert to inspect before purchasing.

9. Importing a BNR34 Engine

Importing directly from Japan or New Zealand can often be cheaper, but comes with logistical challenges.

Key Considerations:

Customs duties and taxes
Shipping fees
Import paperwork
Emissions regulations (especially in California, USA)

Using a licensed importer can simplify this process.

10. Installation and Compatibility

The BNR34 engine is compatible with:

Skyline GT-R R32 / R33 / R34
S-Chassis swaps (240SX, Silvia)
Z-chassis swaps (Fairlady Z/350Z with major modification)

Things You’ll Need:

Engine mounts
Transmission (Getrag 6-speed or RB-compatible 5-speed)
Driveshaft alignment
Wiring harness adaptation
ECU tuning

11. Legal Considerations

Some countries (like the USA) have strict emissions regulations that can make RB26 swaps illegal in road cars unless properly certified.

In the USA:

California requires BAR certification
Use of OBD-II systems may be required for newer chassis
25-year import rule applies to complete vehicles

Always check local emissions and DMV laws.

12. Restorations and OEM Parts

Finding OEM parts is becoming more difficult. Look for Nissan Heritage Program offerings or used OEM catalogs.

13. Maintenance Tips

Routine maintenance is key for longevity.

Key Maintenance Tasks:

Oil change every 3,000–5,000 miles
Check turbo boost levels
Timing belt change every 60,000 miles
Monitor for head gasket leaks
Use premium fuel (95+ octane)

A well-maintained RB26DETT can last over 150,000 miles.
