Guest duende1933 Posted October 2, 2003 Share Posted October 2, 2003 I have a 280zx turbo engine in my 73 240z. I would like to use the 240 tachometer to keep it as original as possible. What kinfd of modifications do I have to do or what year tach may I be able to use. Is it possible? Quote Link to comment Share on other sites More sharing options...

Drax240z Posted October 3, 2003 Share Posted October 3, 2003 Or swap the guts from a 280z tach into the 240z case. Bridge the large (30 Ohm) resistor on the signal line, calibrate the tach, and you are set. Quote Link to comment Share on other sites More sharing options...
