400hp?

MZ DAIZY

I’m guessing this is measured at the crank. If so that puts it at about 325 - 340 WHP. $4000 worth of bolt on’s with a tune, on a 370 puts out 320 WHP.

I’ll give you the factory warranty is important, but I’m pretty sure you modify this, Nissan will kick you and your Warranty to the curb.

Not much more bang for the buck....

Was just thinking the same thing.

Obviously the VR will be the better platform to make more power as its already boosted from the factory. Mod for Mod $ to $, the VR will make more power.
Maybe the bottom end will be forged? We can only hope...

To each his own... I like the upgraded interior, the new look exterior and the warrantied 400hp turbo powertrain. I think it's worth it. I mean, it's only 40k$.

I too like the new dash and glad that they kept the tri-pods. I noticed the seats and door panels are very similar to the 370z.

The exterior design is very clean as compared to the Supra with all these fake stickies. $40K is great, but let's wait til the official announcement and if the stealers will mark it up $5K.

I am curious if they changed the clutch hydraulic to eliminated the dreaded CSC issue.

And it looks like they kept the same e brake handle that the 350Z, G35, 370Z, G37 share. I see a few custom e brake handle sales in the future

700+whp

Its basically a refresh. Aint nothing wrong with that. Overall they did a good job. Its obvious they reused a lot of the same stuff. Especially the interior. But what do u expect from a struggling company.
I wished they would have bumped the hp to 420 at least. Or higher tq. A bit lazy. Unfortunately more and more cars are being hybridized etc and cara will be more boring, they might as well go all out.
That would of been a nice suprise.
But have the improved on the chassis etc?


I'll be in my bunk!

I've seen a lot of posts of the Infiniti Red Sports dynoing anywhere from 350-385whp so the general consensus is that the 400 is a bit underrated.

It's a ton of bang for the buck compared to the 370Z.
Better cooling from the factory, a much fatter powerband, launch control, mechanical LSD.
More tech, nicer interior, launch control.
The only reservation I'd have is EPS.

It's not that simple. Here's some facts gleaned from Infiniti Q experiences during the VQ/VR transition:

-The 400HP is underrated. RWD cars are getting very close to rated crank HP at the wheels, this is proven by years of dyno comparisons. (AWD Q60 weighing 600+ pounds more than this Z can get to 60 in 4.4!)

-The VQ is a high-revving, moderate torque engine. It's actually better than most other NA designs, however the VQ is WAY down on OVERALL power. The torque from the VR30 is available from 1600-5600 revs, whereas what little torque the VQ makes is at a peak. The VR30 has a very broad power band, and makes more power all the time than a VQ. Also, think about driving at elevation, it'll be a revelation!

-The VR can be tuned way further per $ than a VQ. JB4 piggyback will give you a very noticeable kick in the pants. VQs need an optimistic butt-dyno.

-VR is smoother than VQ, which can seem agricultural (to me at least, but VQ exhaust sounds awesome) with the windows closed.


The VR is not perfect, the VQ will likely beat it out for long term reliability since it's not boosted, but for enthusiasts it's a WAYYY better engine.

Without a doubt the VR is a much better engine platform, as soon as it becomes more widely accessible in the Z's more companies will invest in development for it. As I understand it the best built VR's are stuck in the 800whp range? I'd guess this will change soon enough now that there will be more demand.

My only real complaint about it is it's direct injection only, so either frequent walnut blasting is required or a good catch can setup early on.

tvfreakazoid

This is a known issue with carbon build up, so why didn't they also add port injection. Makes no sense. Just another expense unfortunately

Yes. I trust Tamura to get the steering feel done right.

With an AMS Stage 2 Performance Package, you are up to around 430 hp and 475 lb-ft of torque.

Spooler

It is an open deck block so I would suspect the VR30 will still have the same issues with sleeve walk and head lift as the VQ's.

I previously owned a 2016 GTI with DI. Only the NA GTIs came with DI, the ROW GTIs had dual DI/PFI, and a few NA guys did swap the PFI stuff onto their GTIs and reprogrammed the ECU to run it. Also took a custom subharness to connect the injectors to the ECU (where on the NA cars the pins were added to the empty connector positions).

The GTIs and many German DI cars had ridiculous carbon buildup. My exhaust always had thick, sticky, black residue on it, and pics of GTIs getting their valves blasted showed huge boogers of carbon buildup at shockingly low miles. Basically, by 30K miles your engine performance would be seriously impacted by carbon buildup.

I did look at Infiniti Q cars carbon buildup threads and pics online, and the pics of the VR30 carbon buildup seem significantly less severe than the German cars were (I saw "were" because I don't follow the latest German cars anymore). Although not ideal, it looks to me that carbon buildup in the VR30 is so much less than what I've seen before, I'd bet you could go quite a while before having a measurable negative impact on engine performance.

I don't understand why Nissan didn't employ some kind of strategy to deal with carbon buildup, it seems irresponsible for any manufacturer to continue using DI that worsens long term maintenance costs. Heck, our $20.7K 2020 Corolla with the 2.0 engine has dual injection D4S on it!

*J*ap***V*et*

Take that same 4k and put it into this new Z and then we will all see the difference. Are we forgetting that this is a twin turbo car. I for one can't wait. The cost of TT'ing the 370 is outrageous and that 10k would be a mighty sizeable down-payment towards a newer car but familiar platform.
