The VQ30DETT is Nissan's current engine of choice for Japan's top-tier motorsport category did you say? You're a bit behind the times there
Did you also not read this part:
... it's not entirely about super dooper RB26 busting performance. Exlusivity plays an equally big part as does ultimate performance. Thats why the engine isn't a VQ, and that's why the engine isn't a VK.
It's funny you say the VRH35L is hardly a test bed for a supercar engine when the VQ has been ditched this year in favour of a VK for the GT500 Fairlady Z. It's not like Nissan had a few 1999 VRH blocks lying around and has 'blown off the dust' and used them again 8 years down the track. The new engine - according to Holiday Auto - is a recreation of the VRH35L albeit in 3.8L V6 form with VVEL (2007 tech right there), twin turbos with integrated exhaust manifolds (never heard of that before), semi-wet sump, and Euro 5 compliant emissions. So the game has lifted since 2000? Good thing the new GT-Rs engine has too
Btw, the VK is based on the VQ, not the VRH (VH)
