gauges

im swaping a non turbo auto to a turbo auto . what going to happen wiht the gauges in that car when i put the new motor in . what gauges are to work if any at all.

All gauges except the tach will work perfectly, there is a resistor in the tachometer that needs to be changed, or simply get a turbo tach from the same year (87-88 or 89-92) Turbo Supra. The only thing you'll need is an aftermarket boost gauge and a place to mount it, then you can keep your voltmeter.
