Ok I was thinking that since my tach will not go high enough anymore I need to add a Autometer tach, and since I have to run a boost,a/f,gauge I thought Maybe I would add oil,temp, and volts. Since I do not need my SI cluster anymore could I use like a hf or std speedo with Idiot lights (do they make them that way?) in place of my SI cluster? Will the Idiot lights work with the sensors that are on the motor? It would be nice to run the gauges and have the Idiot lights as a back-up. Anybody do this?

 

well...
if its a 90-91 ill trade u my STD gauge cluster for ur Si one.... fair???

 

sorry it's an 88 otherwise I'd be interested. anyway back on topic. anybody?
