Given Nissan's mandate for having as few engine families as possible, I would say it is highly unlikely to see any engine options for the new GTR. My guess is the VQ35DETT or something very similar in the VQ family. Nissan just can't afford engine options on a limited production car and still make it affordable (i.e. $70k).

The Nissan VQ engine family is a 2.0 L to 4.0 L series of V-6 piston engines . It is an aluminum DOHC 4-valve design. Later versions feature variable valve timing. This engine is widely considered to be the world's benchmark V6 engine for its combination of smoothness, reliability and high power output.

The 3.5 L (3498 cc) VQ35DE is used in many modern Nissan vehicles:

• 2001-2004 Nissan Pathfinder (240 hp)
• 2002-2004 Nissan Maxima (255 hp)
• 2004- Nissan Maxima (265 hp)
• 2003-2006 Infiniti G35 (260 hp to 298 hp)
• Infiniti QX4 (240 hp)
• 2002-2004 Infiniti I35 (255 hp)
• 2003- Nissan 350Z (from 287 to 301 hp)
• NismoZ S-Tune GT 295 hp (VQ35DE S1 engine)
• 2002- Nissan Skyline (V35) (280 hp)
• Nissan Stagea (M35) (272 hp)
• 2003- Nissan Teana (350JM-J31) (231 hp, 333 nm)
• 2003- Nissan Presage
• 2004- Nissan Fuga (280 hp)
• 2000- Nissan Elgrand (245 hp)
• 2002- Nissan Quest (240 hp)
• 2004- Nissan Murano (Z50) (245 hp)
• 2002 - 2006 Nissan Altima (from 250 to 260 hp)
• Infiniti FX35 (280 hp)
• Renault Espace (241 hp)
• Renault Vel Satis (241 hp)
• 2006 - Samsung (Renault) SM7 NEO-VQ
