hi, i buyin a autometer boost gauge for a 2 litre turbo motor. never had aturbo, and lots of diff boost gauges. who knows what is suitable. motor in street car not built for racing. thanks greg
just get a $49 from autobarn .
The variations are really only dependant on boost pressure, some have a higher scale for higher boost, get the one that you like the look of, isn't cheap and NASTY, and covers with some margin the level of boost your engine will see.
Also consider an electric boost gauge over one that runs a boost/vacuum line. A lot easier to run wires, rather than the boost line/tube.
