I would like to know if it is possible to replace a JDM Gauge Cluster which shows 180km/h with the typeSH OEM gauge cluster that only shows 150? Ive seen some with 220km/h. Can I install either one without doing anything else? If I hit 50mph will it show as 70mph? I sent a message to a seller on Ebay and he told me hes had people buy them off of him and install them without a problem. Is there anyone in here that has a cluster with 180km or above that does not have any issues? I would really want to swap to a 180km one. Thanx
