once i drop in a gsr motor into my civic lx.. do i need to change out my guage since my redline is different or can i use the stock one that came in my civic???? i no its a dumb question but just need to no haha

 

You should be able to use ur old one but the redline might be different so if ur old one tops out at 7k then u wont be able to see ur rpm

 

you can use your lx tach,you can also get those pretty 15"tachs wit the shift light but the choose

 

please only post one topic about the same exact subject..

Just keep that topic, let this one die, you can keep the guage cluster, your ECU is probablly the reason, it has nothing to do with your guage cluster, either the ECU, wiring is wrong, or a sensor is not reading what it should (like the oil press. sens)
