Sport Comp boost gauge, mechanical 30vac - 20psi boost. - $30 shipped
Sport Comp II EGT gauge, 0-2000F w/ thermocoupler $ 80 shipped
Boost gauge I bought and then found I already had a sportcomp 2 boost gauge in the garage.
EGT was used on my fathers old 3000gt vr4, been sitting for a few years unused since. Both in good shape.
