Well i couldn't resist on this thread, on my Z though only goes as fast as most of you can push, spend most of time on jack stands. Update to come here soon.
My 85 300zx although, completly stock, one night had her up to 220km on empty stright highway, and still had room to play just didn't have the guts, getting little floaty at that time. If anyone wants to convert to mph, see how that compares.
