i was just wondering how much it would cost to get either of these fitted. not sure whether to attempt it myself or go to a garage and get it done.



guages i would want to fit would be turbo pressure, oil pressure, and oil temp.

 

Turbo BOOST. Gauges are relatively straightforward, there are threads galore on here to help you.

Your car already HAS a dump valve, the one fitted when it was made, as specced by Subaru themselves and endorsed by Prodrive and every other reputable tuner. Why change a winning formula?
