Hello,

I just purchased a 91 rx-7 and in its current setup with a sr20 DET swap, the speedometer does not work. I was looking for advice for either replacing it or somehow adapting it to work. Any advice?

Thanks

 

You most likely need an adapter to get the stock speedo to work on your "new trans".
I'm guessing that is why the other owner didn't hook up the speedo.

 

Do you know of any adapters you would recommend? Im new to the car working world so i dont know too much about it.

 

Go to the junkyard and look for a speedometer cable off of whatever the trans you have in it came out of. You'll likely have to piece something together using a speedometer cable repair kit and junkyard parts.

 

Try posting in the Other engines Section.I am sure that many guys have encountered this problem...Just not me,haha,as I am a Dorito head!

put a rotary back in it. this will fix all problems :P

 

well looks like all i need is an s14 speedometer gauge. Thanks for the advice tho.
