How much are gauges and install for aftermarket?

How much/where do I buy gauges / kit to install them into an rx8?

I'm trying to turbo the car, would need in the likelihood about 5 gauges.



Thanks.

Hit me with some answers.



Also, What is the best place to buy replacement bushings for all of the necessary places @ 70k miles and I'm probably going to switch to coilovers.



Is a pinion snubber recommended on these cars? Which one?



thanks again.
