Ok so im assuming that my stock hf gauge cluster wont work with the swap i have (B16) because its mechanical and the tranny isnt, well the tach works, but not the speedo. I think my rpm's might be off as well would any know if thats commen cuz im think its about 500-600 off. but um is their an siR cluster out there that reads in miles that i can get and do i need to change the wire that connects to the tranny? thanks peoples

 

Your speedo should plug right in. As long as you take your old speedo gear off from your HF motor and put it in you B-Series tranny then you have your speedo.

My stock RPM guage is also off but that is to be expected that is why most people have those aftermarket ones.

You shouldn't have any problems, just make sure the speedo wire is plugged in all the way.
