I'm really not sure where this would go so I will just post it here. How hard would it be to install all three stock gauges on a car by myself? Keep in mind I have minimal knowledge about such matters. Is it even worth the effort or should I just have it done by a professional?

Okay someone out there has had to try this. :confused:

turbo gauge is pretty easy...
nothing to the voltage gauge.

the oil temp gauge is a little more chalenging and I wouldn't recommend it.. you will have to pull the alternator I believe.

I installed my own boost gauge and am having the dealer install the egt and oil temp...

There is a link to the install for the RS performance guage pack. I'm guessing the turbo boost would be somthing similar to the Vac install but I can't be positive.
