Nissan/NISMO made a special version of the RB26 for GT racing. This RB26, was stronger than the standard blocks. This GT Block, or RRR block also found its way into the 20 very special Z-Tune versions of the R34 GT-R.
The Z-Tune (Spec 2) Engine Concept, produced more than 500 ps, and 55 kg/m.
The heart of the NISMO R34GT-R Z-tune that exhibits such dominating power performance is the RB 26DETT Modified Z2 engine.
To achieve an engine that generates high power/torque of more than 368 kw (500 ps)/540 N/m (55 kg/m) and provide the high durability required of road-going cars, plenty amount of techniques and know-how that NISMO accumulated throughout the racing scenes, have been lavishly adopted into this Z2 engine, that some may even find the quality to be too much extreme for a road-going vehicle.

Back in 2005 when the GT Block was released, the price was 270,000 yen, about double of an N1 block. It was a pretty rare block to see for sale in the wild. They trade hands now for very large sums of money.
