Having shifted on time for years I can tell you your car will most likley need to shift somewhere between 2.1-2.7 sec depending on rear end gear, trans ratio, hp etc. If you have a computer or a playback tach it would make much easier to pick your exact number, otherwise start on the low end and work your way up to your desired RPM. Good Luck
