jeffer949 Posted August 5 Share Posted August 5 Does some one know how fast you can set the cruise on 280zx or a z31 300zx? by that I mean is there a limit to the speed it will allow you to engage cruise control? I have a 1984 maxima wagon and my cruise works fine except that by design it wont allow me to set cruise past 75mph. Is this limitation the same on the 280zx and the 300zx? I'm looking to swap in a cruise control module from the same era of car that doesn't limit the speed. Ive already looked at the wiring and the 280zx looks to be plug in. and a 300zx will have to be reworked but doable. Thanks in advance.

G-Tech Posted August 6 Share Posted August 6 If i still had cruise on mine, i'd be happy to find out for you. But i don't have it no more. Props to you for thinking you need a cruise control unit that goes higher than 75. Good luck. Hope someone can help. Quote Link to comment Share on other sites More sharing options...

Interstates are 75mph and traffic goes 80. Turnpike speeds are 85. Quote Link to comment Share on other sites More sharing options...
G-Tech Posted August 8 Share Posted August 8 Well my stock speedo only went to 85mph and i know it was revving a lil high at that point for long distance driving. But hey, if you have 75mph posted signs and your car don't mind 85-90, then u have a good car! I can't imagine an original 84 Maxima wants to do that speed anymore than my zx did when it was stock. Sorry i cant be of any help other than replying to your post, to keep it fresh Quote Link to comment Share on other sites More sharing options...

It goes 80mph at 3k with the ac blowing cold and will stay cool even in 100 deg heat. But thanks. I think im gonna just have to buy one to try Quote Link to comment Share on other sites More sharing options...
