Apart from the progress of sketching to prototype development and finalised design, not much has been shared by Nissan on the heart of the commemorative Nissan GT-R50 by Italdesign.

Nismo, together with Nissan Technical Centre (NTC), have now shared their build list for bumping up the power outputs of the 3.8-litre VR38DETT engine in the Nissan GT-R Nismo model from 600 hp to 720 hp.

Pushing out an additional 120 hp (this is even more than what the new Almera Turbo has!) requires more than just a pair of new turbochargers and an ECU (engine control unit) upgrade. Nismo listed new items specifically just for this project that includes exhaust system plus catalysers, pistons, connecting rods, connecting pins, crankshaft, camshafts, intercooler and associated plumbing, intake manifold and air filter casings.

More energy also means more requirements of fuel, thus new fuel injectors and a higher-flow fuel pump are also part of the upgrade “recipe”. Nismo and NTC said approximately 12% of new parts were developed just for this special project. Many technologies and learnings from the Nissan GT-R Nismo GT3 racing machine were transferred to the development of these new components.

In detail, the heavily revised V6 engine in the GT-R50 develops 720 hp at 7,100 rpm and 780 Nm of torque between 4,800 to 5,600 rpm. This is a 120 hp and 128 Nm increase over the already special made-to-order Nismo GT-R engine dishing out 600 hp and 652 Nm. 

All that increase in power still meets the strict Euro 6 emission regulation, which is important as many of the GT-R50 by Italdesign will find homes in Europe. Nismo and NTC also upgraded the transmission system to handle that enormous increase in power.

Based on internal tests, the GT-R50 by Italdesign manages to reach 200 km/h in 0.8 seconds quicker than the normal GT-R Nismo from a standstill. No specific result was shared as the chart had its timing and speed blanked off.

For reference, the engine outputs in the “entry level” 2021 Nissan GT-R are 570 hp and 637 Nm of torque.

A test car was also developed to test various new body parts such as the retractable rear wing, panels as well as chassis rigidity.

To recap, the project was conceived to celebrate the 50-year anniversary of both the GT-R nameplate and the revered Italian design house with only 50 units of the million-dollar (EUR990,000) special will be built. The GT-R50 will be finished with liveries inspired by the most successful race cars to carry the GT-R nameplate, likely making all 50 units to be completely bespoke.
