Default About Z speed limiter?

My Z came from Japan, I am not sure there is a limiter or not...

Do we need to make some modification to get full top speed?

Of hand, my Z dash only show a max of 180KMPH to 200KMPH.. i forgot.. got to go back and check

I do believe there is a speed limiter. That's why HKS offers a Speed Limit Defencer which overrides the speed limiter specifically for the Z. Check for HKS parts in your area or directly from Japan.

The JDM cars have a 180kph limit and other markets a 250kph limit apparently (only found out about the 250 a coupole of weeks ago).

Unless you plan on going more than 150mph I don't see the point in removing the limiter.

Wish I had an accessible track to get up to those speeds

Anyway the HKS version (assuming they have one for the Z) is called the Speed Limit Defencer. There's lots of other brands as well. Pretty much all Japanese tuning houses will have one.

HKS Speed Limit Defencer - Japan Website

The Z33 uses the Type III SLD. US prices for the SLD (don't know if the Type III for the Z33 is available here) is $100-150.

I'd hazard a guess of about 270km/h maybe 280km/h before you ran into the redline. You're going to need a decent straight to get there and pull up again.

One last question, for different kind of limiter, does it perform differently?

I don't have any personal experience with them but I doubt it. All they're doing is removing the artificial speed limit.

Cars sold in Japan are limited by law to 180km/h. At least that's my understanding of the situation.

Cars sold in other markets typically have no limt or a very high one. In this case Zs not sold in Japan have a 250km/h limit.

Yes, the same as yours although the JDM cars have more to gain seeing as they have a lower limit to start with.

No matter which car you're going to run into a limit set by gearing and rev limit. I don't have the final drive ratio or I could work it out but my guess is between 270km/h and 280km/h
