It's not small enough displacement to where it needs a turbo in order to make up for the lack of displacement, but at the same time it's not going to produce as much torque as an NA v8 would. Don't get me wrong, I love the VQ37, it performs EXTREMELY well and makes a lot of power for an NA v6. But at the same time the VQ37 seems a bit out of place in a performance-oriented vehicle, imo.
So from 240z to 260z to 280z/x to 300zx (.2L increments), to 350z (.5L) to 370z (.2), I suspect the next logical step is 390z? But that just sounds weird and not as "catchy" as the other Z models. That's why I'm voting for a 400zx or 420z, or even 560z. They already have the 5.6L developed why not use it?  |
I don't think the displacement is such an issue. A V8 is just better, and easier to make more power with. You can only flow so much through a set of heads, and if you add 2 more pistons, you get more headflow. Larger valves just waste more space in a head after a certain point, and you need another cylinder rather than just increasing bore/enlarging valves and wasting space. An engine is just an air pump.
