Don't have a motor yet, let alone a fuel supply (LOL), basically trying to collect all the Six conversion pieces while waiting for a good deal on an engine to pop up. You know of one? Will the engine determine which tach I need? Thanks ..

It really depends on the engine your going with... All the 911T with carbs and the 914-6 are the same. The impulse signal is the same. It gets tricky when you get to the CIS engines in ~'73/'74. Then i cannot say with certenty. But, with the 3.2 i know gets its signal from the motronic brain. I'd wait till you get the motor, cause a used tach isn't all that expensive. North Hollywood Speedo does conversions for tachs, so if you want a vintage tach with a 3.2 inner workings, your gonna have to folk over the dough...

Hope that helps, Don.

Thanks for the advice, I may go ahead and pick up the 911T tach anyway since it's only $35 then resale it if I go with a larger engine.

To get even a little more detailed:

Tachs with regular points ign thru 3 pin CD boxes

Tachs with 6 pin CD box

That is pretty much how they are divided up through 89' I believe.

3 pin CD's were used through the 2.7 series and the 3.0's were the first to use the 6 pin.
