HKS can now update the R32 Skyline GT-R's RB26 with modern tech, 600 PS and 5 L/100km?

HKS has showcased a new line of products for JDM enthusiasts, the “HKS Advanced Heritage”. Due to high customer demand, they have introduced a modernization package for the R32 Nissan Skyline GT-R RB26 engine, the “RB26 Advanced Heritage”.

By “modernization” we mean providing immense power, whilst still complying to Japan’s latest emission regulation and being somewhat fuel efficient. With the Advanced Heritage package, it is claimed that 600 PS could be extracted from the classic inline-6 engine.

HKS claims a fuel consumption of 5 l/100km is attainable but that is most likely in perfectly ideal conditions. You don’t get an RB26 to be fuel efficient.

Although mainly showcased with the R32, the "RB26 Advanced Heritage" is available for all Nissan cars that are compatible with the RB26 engine.

The original RB26DETT had maximum power output 280 PS at 6,800 rpm. Extracting a further 320 PS while still keeping the car “Streetable” and reliable meant some extensive work needed to be done.

Some of the work highlighted in the RB26 Advanced Heritage are the:

• Pre-chamber combustion
• Vertical turbochargers
• Dual plenum intake
• Dual injection

The pre-chamber combustion allows for quicker ignition, while the vertical turbochargers allow for optimum exhaust flow to reduce pressure loss.

The dual plenum intake ensures each cylinder gets equal airflow, and the dual injection improves fuel atomization.

The RB26 Advanced Heritage by HKS is perfect for those with a taste for the JDM classic. Who knows, if demand is good for other classic JDM engines, HKS might just have another “Advanced Heritage” engine in the making.
