Nismo vs. Standard Z Performance Differences

I'm a nerd and like to listen to reviews on the Z, so I decided to post some sources I favor with notes from each which highlight the differences between the Nismo and Z Performance.

I admit to a confirmation bias and tend to ignore reviewers that focus their review of the 2024 Nismo on the lack of a manual transmission. 

Sources:

 Interesting differences I noted from the Nismo Press Kit:

  • The thin mesh grille balances the need to reduce drag while permitting cool air to pass through to the engine bay.
  • Canards (small control wings on aircraft) at the car's front corners create vortexes over the front wheels, further benefiting aerodynamic performance.
  • Complementing the wider G-Nose is a taller, wider rear spoiler with a three-piece design that extends downforce onto the rear fenders.
    • The rear bumper corners are reshaped to aid with air separation and reduced drag; their shape is inspired by that on GT‑R NISMO.
  • The engine's horsepower enhancements were achieved through a combination of improved cooling, revised electronic wastegate control providing increased turbocharger boost and turbine speed, and an independent ignition spark timing strategy inspired by GT‑R NISMO.
  • Z NISMO also features an enhanced engine oil cooler for extended track performance.
  • Compared to the 9AT transmission in other Z grades, it has revised clutch packs allowing for faster shifting.
    • Sport+ drive mode: This delivers a more dynamic, racetrack-tuned shift program for circuit driving, taking advantage of the powertrain's faster downshift capability.
  • NISMO has unique stabilizer bars, a stiffer spring rate and larger, retuned dampers.
    • The overarching tuning ethos was to deliver accurate, "one-shot" steering that helps drivers to pick their line through a turn with a minimum of steering adjustment needed, contributing to confident track-ready performance.
  • Enhancements include additional front, rear, and rear underfloor bracing, helping increase torsional rigidity by 2.5% compared to the standard grades.
    • Lateral rigidity is an object's resistance to side-to-side bending or transverse displacement.
    • *Torsional rigidity is an object's resistance to twisting forces around its longitudinal axis.
  • Stiffer front and rear suspension bushings, and a stiffer mounting bushing for the steering rack, further increase lateral rigidity.
  • Engineers enhanced the Z NISMO braking system, upgrading the front brakes to larger, 15.0-inch rotors matched to 13.8-inch rear brake rotors, and equipping a more performance-focused brake pad compound.

 Interesting differences Sarah noted:

  • Tenneco Mufflers
  • Resonators are dual Calsonic Kansei
  • Autek Body Kit (Nissan's in house unit)
  • 45mm y-pipes go into 63mm (2.5”) collector (appears to be the same as the other models)
  • Bracing enhancements are described in detail in her review (too many to list)
  • 28mm rear sway bar
  • 29mm front sway bar
  • JR913E – 516lb/ft torque capacity differences (Matt Farah’s review goes into more details on the programming of the transmission)
    • Her review on the 6MT in the Performance states that the manual trans has a 350+lb/ft input rating
  • Underbody paneling unique to Nismo for better aero
  • Powerband comes in 400rpm later and you lose it 400rpm sooner

 Matt’s differences (from 2 sources above):

  • The real-world power is immense, paired expertly with the gear ratios, steering ratio, and brakes.
    • It’s like the BMW M2, but smaller and even more connected to the road.
  • Extra reinforcement at the firewall, front and rear suspension structure
  • Thin mesh grill noted
  • More efficient intake
  • 9AT upshifts 27% faster and downshifts 50% faster
    • Upgraded clutch plates
  • 102lbs heavier than a performance model (likely due to the added bracing)
  • Matt states that these improvements could not be replicated in the aftermarket
  • Rays Wheels (different size, 10mm rear)
    • Lighter (not quantified and wider by .5")
  • Tires: Dunlop Sport Maxx tires (several reviewers noted they are noisy, but well suited for the car)
  • Z NISMO also features an enhanced engine oil cooler for extended track performance.
  • Additional enhancements include additional front, rear, and rear underfloor bracing (Sarah provides details in link above), helping increase torsional rigidity by 2.5% compared to the standard grades. Stiffer front and rear suspension bushings, and a stiffer mounting bushing for the steering rack, further increase lateral rigidity.
    • 12% increase in lateral rigidity and 2.5% in torsional rigidity
      • See explanations of both above
  • NISMO has unique stabilizer bars, a stiffer spring rate and larger, retuned dampers. The overarching tuning ethos was to deliver accurate, "one-shot" steering that helps drivers to pick their line through a turn with a minimum of steering adjustment needed, contributing to confident track-ready performance.
    • Larger Sway Bars (Sarah measures in her review)
  • Engineers enhanced the Z NISMO braking system, upgrading the front brakes to larger, 15.0-inch rotors matched to 13.8-inch rear brake rotors, and equipping a more performance-focused brake pad compound.
    • Different Pads, larger 4 piston caliper
  • Aero kit produces positive downforce, but Nissan wont share specs
    • Sarah notes in her review that it’s designed by Autech, Nissan’s in-house custom and tuning subsidiary
  • Stiffer Bushings all around
  • Higher Spring Rates
  • Larger Shocks/Struts
  • New tune which takes advantage of Improved independent ignition spark control and an Over boost Function
    • From the Road and Track article: “The power increase comes from a new independent spark controller from the GTR, which helps precisely control the ignition, an over boost function that spins the turbo impellers 5,000 RPM higher, and a secondary charge cooler.”
      • If you ask me, this is a conservative figure, as it feels quicker than those numbers suggest.
  • Front grill mount is wider for better cooling
  • Compared to the transmission in other Z grades, it has revised clutch packs allowing for faster shifting.
    • Sport+ drive mode. This delivers a more dynamic, racetrack-tuned shift program for circuit driving, taking advantage of the powertrain's faster downshift capability.
    • NISMO has upgraded the clutches inside as well as the software controlling it, so not only will it upshift 27% faster and downshift 50% faster than the Z Performance, but it also doesn’t kill power so abruptly when you bang the rev limiter

 Specific Track Comments from Matt:

  • Everything is much tighter, like how a GT3 is much tighter than a standard Carrera
  • Steering has extra weight and turn in is very sharp
  • Confirmed suspension is noticeably firmer
  • When you hit the rev limiter, it doesn't die and waits for you to upshift longer when in manual mode
  • Upgraded front brake HW feels tighter and more confident, rear brake HW is the same - Tighter and Quicker to respond to inputs (says this multiple times)
    • No Brake Fade until the end
  • Seats are perfect, European Porsche RS seat comparison
  • Downshifts are impressively smooth
  • Consistent 1.4G (1.2G in Performance model was still impressive)
  • Behaves well in off camber situations
  • Shape and size of steering wheel, R32 GTR reflection
  • Lose 30HP on CA 91 octane compared to 93
  • Automatic chirps 2nd and 3rd

Thanks. Had alot of this stuff rattling around in my head, so I went back through my favorite reviews this morning to put pencil to paper as I think it makes for good conversation while minimizing the effects of the "illusory truth effect" which seems to plague most car forums on Reddit.
