There is no speed limiter from the factory on the zenki JDM cars, but the newer ones do have the speed input and presumably cut out at 180km/h.

You can simply cut this wire to remove the speed limiter:

Big chance many of the JDM cars have received this cut already.
Also from what I understood cutting the speed input on the 20v ECUs changes their rev limit to 7600rpm.

And then there is also the chime that operates above 100km/h, which receives the input from the gauge cluster directly.
