Interesting. I doubt it would be from increasing bore since I doubt there's much left between the cylinders. You guys should work for Scotland Yard.

Yeah the GT-R block has the same bore, just different slightly different stroke. There really isn't much room for bore expansion as you've pointed out, the VQ37 is only 2.5mm wider bore than the VQ30.

Only 3 drivers in car #2. Wow.

It is provisional, so theoretically they could add a driver. The cars are locked in however.

Found the official entry list. Yes, the two 370Z's are being fielded by RJN of the UK. No engine specs but they list their displacement as 3.8L, so they may either be running the GT-R block or a custom crank shaft.

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.

24H Dubai - Provisional Entry list 24H DUBAI 2012 : endurance racing for touring cars, GT cars and 24H Specials by 24H Series

could be the Z33 380rs crankshaft since that was pretty much made for racing as it was with the traditional 95.5mm bore and enough stroke for 3.8L. it made 350hp @ 7200rpm in race trim (assuming race gas) so it could theoretically get close to 400 if reved up and over 8k rpm without loosing much torque

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.

it's not the heads themselves, it's the VVEL system. that's why the GTR doesn't have it... yet

370Z currently 4th-in-class in qualifying. Seems there is a "slight problem with the brakes". LOL.
