  1. Lowering springs question

    RSR is the way to go, they are made in Japan, good quality and designed to work with the stock dampers, and give a small enough drop that you can tell, but does not affect the ride quality (improves it) unlike the swifts which people report make the car bouncy and super low.
  2. Nissan Z’s Twin-Turbo V6 ‘Is Capable of a Lot More Power,’ Nissan Boss Says

    I am not sure what the benefits would be, if the car is not going to be used on the track on a regular basis, I don't see why a Nismo would need anything for the street.
  3. Nissan Z’s Twin-Turbo V6 ‘Is Capable of a Lot More Power,’ Nissan Boss Says

    It all depends on what your goals are, and I would not say the mishimito is any better then CZP HX or the AMS. Most of what I have seen is that there are not the same colling issues on the Nismo as the other models, since it has improved cooling.
  4. Nissan Z’s Twin-Turbo V6 ‘Is Capable of a Lot More Power,’ Nissan Boss Says

    You should not need a heat exchanger on the Nismo, the cooling is really good and has extra coolers. You can if you want, but it's not a priority like the performance or the sport Z. Also, you have 420hp at the motor, not the wheels, but since Nissan increased the HP, you will get fewer gains...
  5. Nissan Z’s Twin-Turbo V6 ‘Is Capable of a Lot More Power,’ Nissan Boss Says

    It depends on how you define the sweet spot. 500RWHP on the stock turbo's is close to the ragged edge. The stock turbos are way out of their efficiency zone at those numbers and put more stress on the engine. A properly sized turbo and a fuel/ethanol set up and tune, will get you very safely in...
  6. Lowering springs question

    I am not sure on these, but it's what I have, and I can tell you the ride is better than stock and the car handles so much better. The biggest issue I had was the squat and nose dive on this car, and these springs fixed that, best upgrade I have done, and the drop is subtle enough to look good...
  7. 2023+ Nissan Z Wheel Spacers

    I went with Eibach, they make their own studs and spacers in Germany, and they are approved by the German DOT, and are some of the highest quality hardware I have ever seen. They sell a kit for 15mm front with the extended studs included and the 20MM rear with the extended studs. The kit is...
  8. 2023+ Nissan Z Wheel Spacers

    I have 15MM front and 20mm rear slip on spacers with new wheel studs and of course they fit stock wheels. Only spacers that would impact the wheels would be bolt on spacers.
  9. New Wheels: VFC Performance FC5-SL Forged Monoblock

    They look great, good choice. Good to see someone actually upgrade, too many people remove the forged stock wheels, only to put on Chinese cast of flow formed wheels. I bet they were not cheap, but totally worth it, your car has a great stance I would not touch another thing, just let it ride.
  10. Nissan Z cracked cylinder head/ "porous block"

    You wont have any issues, Z has been out since 2023, and the VR30 in the Z has not had any issues with the heads of any kind.
  11. Wheel spacers

    Dude, take some meds.
  12. Wheel spacers

    You are saying 15mm do not fit, that's a generic statement. Maybe bolt on's, but I would never use them, some others like them, but I don't. It takes no time at all to replace the studs and use 15mm, which in my opinion works perfectly on the stock Rays wheels. What do you mean the 20mm require...
  13. Wheel spacers

    That’s not true, if you change the studs and use proper slip on spacers 15mm are perfect , it’s what I run.
  14. Wheel spacers

    I went with 15mm front and 20mm rear and it’s perfect. I don’t want any poke just a bit more flush, with RSR springs. Car looks perfect. I did the studs and slip ons, which I prefer over the bolt ons.
  15. Lowering springs question

    Road course or drag? If you plan to road course and are not super experienced, then the stock sport will be fine until you start pushing the car. However, when you track any car, there are some baseline upgrades, unless it's just a track day once or twice a year. Upgrade the brake fluid to dot4...
  16. Want a 400Z to modify, should I start with NISMO?

    re the car is in the shop. Kevin Bonds is my hero. You won't have an issue with the 6 MT, the only issue would be the clutch if you end up upgrading the turbo's but that's normal on any car. In my opinion, unless you want to go nuts, these cars do very well without upgrading the turbos, which...
  17. Question on running extended studs and spacers on stock wheels

    Only ones I would trust are the EIbach. Just go on their website, search for the slip on's, they come with the studs, the spacers and studs are a machining work of art, made in Germany. This is the link for the 15MM and what I bought for the front...
  18. Want a 400Z to modify, should I start with NISMO?

    I agree on the mustang, but man, what a platform. You can buy a five- or six-year-old mustang 6mt for peanuts slap a supercharger on it and run 10's.
  19. Want a 400Z to modify, should I start with NISMO?

    If you’re dead set on the Nismo, go for it. But the thing about the Z, unlike some other sports cars, is that the Performance 6MT has basically the same drivetrain as the Nismo. Yes, Nissan says they improved the shifting feel, and yes, the Nismo makes a little more horsepower, but not enough...
  20. Misha roasted the Nissan Z

    I’ve owned several performance cars and tracked a few of them. I had a C6 Z06, which was an amazing car, but after 20–30 minutes on track, the oil temperatures were getting into unsafe territory. I also tracked an Audi RS4 and had cooling issues, and I had a 2013 GT500 that I took to the track...
