Hey Daniboy did you manage to find out if it works with our speedo gears with out any modification? or do our spedos run off the abs ? slightly confused lol.. Regards dave Edit: Has any one tried one of these guys yet , im very tempted but every single forum site is saying the build quality is poor and they need to be rebuilt, i wonder if the lsd would be strong enough with our engines in n/a condition. Has any one done a obx lsd rebuild by any chance ? Regards My one looked good quality lots of Honda people run them no need to rebuild after 40,000 km! Still working good Did you DIY it with the washers, or did you get someone to do it for you? Can you make up another one if sent over to you? Best to get the factory one out theres a guide on newcelica for doing the lsd somewhere Then check if it needs the speedo ring if your mechanic says yes it does Then take obx and factory one to an engineer with a spark eroder cost me $100 bucks to get done Then the factory ring fits on with a a thin slice of metal to keep it in place Is that pretty much it? If there is more detail required within the steps, do you mind Pm'ing me all the information you know about it?
