i bought gauges out of a 83 rx7 and tried to put them in my 80.. i cant get it to work. anyone have any ideas.

 

'79 and '80 have a completely differant setup than '81-'83. There is a site with a conversion that has been done. I will see if I can find it.

 

ya, sa to fb, thats the 85mph speedo as well correct?

 

yea thats why i want the one from the 83 bc it was like 15 bucks and it goes to like 120 or 140 somethin in between there

 

(not related to thread but you dont need to put a title on every post, just the first one)

You will probably have to switch up the sensors as well (maybe maybe not), IIRC some of the resitances changed so they will read different or not at all
