I thought that might be the case as well but I know that people with the rb20 swapped into an s13 have been able to get the entire cluster to work correctly, including the speedo. Any further input is greatly appreciated!dekand wrote:problems would be the speedo wouldn't work cuz the r32 is cable driven, i dont know if the redlines are the same but thats not really a "problem" mainly just the speedo, and if the speedo doesn't work then its kind of pointless in my opinion. Youd be better off using the ka cluster and modifying it in my opinion...
