Well, you can use the stock 92-95 LX/EX/Si clusters since they have the tach. As far as the CTR, or any other 94-01 integra cluster, you have to re-wire a few things as well as make it fit. It is possible. Do a search on this as this has been posted recently. I assume you have a the cluster with no tach on it now like on a DX or something right?
