i read an article that Vquick posted in the skyline forum....and according to most reports, they are going with something more of the lines of the VQ3?DETT, featuring a unity with cosworth to create this thing.
articles are talking about electronically assisted turbos to a electronically controlled system, where the engine turns to N/A at normal speeds and idling and such. also, something about turbine anti-lag system.
if your interested
HERE is the full post by VQUICK!!!
My Opinion: As long as it is Twin Turbo'ed i think it will be one hell of a performer. knowing nissan though, they will offer japan a Twin Turbocharged Beast and then send the US a naturally aspirated V8. Like we need another one of those things.
