What are your concerns for the next Z? Besides the motor. I think we’re sure about that platform.
From my 370Z track days or just plain spirited driving I hope Nissan addresses the fuel starvation issue. If you don’t know already when the car got down to half a tank and you took a hard long right hander you’d get no fuel pick up and the car would stall and would take a minute or two to get it back running. All due to the location of the fuel pump and the size of the swirl pot. This just shouldn’t happen. Luckily CJ Motorsports came up with a very nice solution ($1,200) for this but it shouldn’t of been an issue. I think Z1 Motorsports has a lot simpler fix and cheaper that was a great fix. Hope they work that out. I know the VR30DDTT has direct fuel injection with a low and high fuel pump setup but I’m not sure of the whole setup and revisions if any in the tank.
I also hope the brake issues/ ABS module is addressed also known as ice mode. A lot of track guys would experience a lack of brake from front to rear under hard braking as if the ABS / programming would struggle with brake bias and freak out the system and some reported you’d only get roughly about 20% of brake and you would have to quickly reapply the pedal one to several times to get the brakes to work probably. I only had it happen one time while others was all the time. I along with other guys had quickly already upgraded to a AP BBK with less aggressive pads in the rear and it never happened again. But not all we’re lucky. With the new Z going to have more power it seems, I just don’t know if the current Akebono brakes themselves regardless of the older ABS system is up to par. Like to see a better Akebono six piston setup.
