Compression, compression, compression

All factory turbo motors like the RB and SR series run low compression at around 8:1 which is ideal for forced induction. The VQ like in our 370'z is a non turbo motor, so it makes power by running really high compression at 11:1 and clever variable valve lift and duration. This is not ideal for forced induction, as the high compression doesn't leave much room for increased boost and becomes difficult to tune and avoid pre-detonation. Heat is the enemy of compression. A full teardown and rebuild is the only real option to drop the compression which is costly...

It's also a LOT easier to fit large turbos to a straight motor rather than a V motor from an engine bay space perspctive.

No one really does this as the RB26 is a stronger motor out of the factory...and the fact GTR's run intelligent 4WD makes them one the best value for money street drag cars ever. My old R32 GTR ran in the 11's on street tyres and stock turbos with just minor upgrades.

The 2JZGTE from the Supra is also a ball tearer of a motor for big boost.
