The 1 GT-R entry is by JRM, also out of the UK. Displacement is listed as 3.8L as well so this looks like a traditional turbo set up.

According to Graeme dal Smith, they are now running 370Z stroke crank (86mm) courtesy of Cosworth and 96.0mm bore to give 3.73 litres. With the VQ30 heads they get 13.2:1 compression. This is all based on the NISMO 380RS Type C Z33 race car specs - just installed in Z34 chassis.

Doesnt surprise me. Most all race cars are running older technology top ends from other VQ series motors. The heads in VQ37 are a problem from what I hear. They generate too much heat at racing RPM levels.
