hi how do i remove the restrictor on my 300zx its a import ive been told the car will not go faster than 115 mph car is in klm how do i remove the restrictor ?

either a ecu chip upgrade or a speedo converter which can be found on ebay.

If i were you id go for the chip as some of the converters simply fool the ecu into thinking its going a different speed, fine on most cars but can upset the hicas on 300s as when your doing 80mph the ecu thinks your doing 80kmph and if you steer the hicas misbehaves.

 

Also how long has the car been over here? chances are its alresdy been done, hacing said that i bought mine after it had been over here a few years and that was still limited, you need to find a nice (private) bit of road to see it is or not.
