Guages... I am at a point with my LS6 Supra swap that I need to get some guages working. What is everyone doing as far as guages go? Any luck adapting any factory guages to the tach and speedo signals of the PCM?

Not sure what year Supra you are working on, but with my 82 Supra I used all stock gauges. Tach required an MSD conversion box to convert the square wave from the LS1 PCM tach signal and you have change the PCM output to work like a 6cyl. For oil pressure I adapted the original sender to the pressure port on the back of the LS1. For water temp I used the Toyota sender and turned it down and rethreaded it to fit in the rear of the passenger head. The mechanical speedo is driven by a Cable-X box tucked up under the dash right behind the speedo head. Cable is only 4 inches long! Signal comes from the 4000ppm output of the PCM. Looks stock. Cost about $400 for everything with most all being the Cable-X.
