A displacement change? Very surprising if accurate. Changes I know off are all turbo related.
I'm not sure if the Q60 version is rated for e85 from the factory, but apparently from what I've seen the Z is. I wouldn't be surprised if that is the change if it doesn't require different heads and maybe even pistons.

that's what i'm hoping for, they are saying 400hp and its really 415-420hp...or just enough to edge out the "zed word" lol.

can't wait to see people start dynoing them...

The Q60 has has been dynoed and it has more horsepower than stated so the Z will be the same.

You would think it's accurate considering one came from the Nissan press release and the other from the Infiniti site. Unless someone made a typo lol.

The B58 displacement is 2998 cc, so it makes sense that Nissan couldn't just leave it be at 2997 and had to beat them there as well 😛

Sorry if I'm going off topic, but the guys over on our sister forum said this motor was a pain to work on and that it takes a ton of $$$ to make power.

I'll just say that some of the comments on that page give me a headache to even read. I'd be more interested in hearing from someone who has extensive knowledge of the VR30 as well as a true twin turbo BMW engine like the N54 or S55 to further understand what "pain to work on" for this engine means.

I'm no expert on the VR30 like they are, so I don't know what all it takes to make power, but can speak from experience that you get spoiled pretty quickly flashing a car from your phone for $300 or even in their case at $541. I think it was even cheaper when I got my licenses, so I'm about as spoiled as they come :p

I won't be too concerned with making gobs of extra power on a brand new car under warranty. I have a separate car for that which is good for 600-700 hp+ on stock internals. Oh, it's also open deck :rolleyes:

You can make a ton of power very easily! If we’re talking 6, 7, or 800 horsepower then yea it may be more difficult than the b58.

Once we get past bolt ons and tuning.. aftermarket turbos are super easy to swap on the Supra compared to the Q60. At least that’s my understanding. So maybe that’s what they’re referring to?

Yes, I can see that as the B58 has a single turbo which I'm assuming can be swapped out from the engine bay. Maybe the VR30 is a PITA to work on, but I wouldn't base it solely on having to swap turbos out from the bottom, when I'm sure many people will do the work on their new Z themselves and not once touch the turbos during ownership.

To add.....

-VR30 6MT has an added recirc valve that the VR30 AT doesn't have.

-You'll be able to mod the VR30 with bolt-ons and a tune utilizing stock turbos well past what you can put down effectively with RWD and most all DOT tires.

I personally feel the BMW RWD cars like Supra can handle more RWD power better than the Z34 chassis will be able to. I've seen what happens when you boost a 370Z or G37 RWD over 500whp, they become a real handful in GOOD weather in the first 3 gears. We'll have to see how the chassis dynamics are for the updated Z34 chassis in the new Z, however I can see quite a few new Z's getting wadded up even with bolt-ons and tunes.
