ooohhh yeah. i think the 5sfe redlines a little higher than the 7afe. however, if you have an operating tach in your cluster, and you are wanting his for another reason, the tach will come out (2 screws on the back i think, and a plug), and your GT tach will go right in, and yes, it will function properly. i have the JDM tach in my celica, and it redlines at 7500, but it reads the RPMs normally. >
