1999 Nissan Skyline GT-R

The RB26DETT engine in the 1999 Skyline GT-R has several well-known issues to watch out for:

Oil System Problems:

• Oil pump failure is the most notorious issue - the stock pump drive is too narrow and can fail at high RPM, leading to catastrophic engine damage
• Oil leaks are common from the front cover, cam seals, and oil pan (this car specifically needs an engine reseal)
• Oil starvation during hard cornering or acceleration

Turbocharger Issues:

• The stock ceramic turbo wheels can crack under high boost (though this car has been upgraded with a Precision turbo)
• Boost control problems and vacuum leaks

Electrical/Ignition Problems:

• Coil pack failures are common, especially on modified cars (this one needs new plugs and coils)
• Injector issues - the 2400cc injectors in this car likely need cleaning from sitting

Other Common Issues:

• Crank walk (thrust bearing failure) in high-mileage or abused engines
• Head gasket failures on heavily modified cars
• Cooling system problems, especially with aftermarket radiators

The good news is that most of these issues have well-established fixes in the aftermarket. For this specific car, the engine reseal and consumables replacement should address the immediate concerns, but budget for an N1 oil pump upgrade if you plan to track it or run high boost.
