Help for timing advance on a porsche 911 T 2.0
 
hello everybody

i have a Porsche 911 T 1969 2.0l with two carbs three barrels weber 40 idtp , a pertronix flame thrower coil, a Bosch distributor ''Yellow tag'' 0231 159 002 with the ignitior system, bkzh unit and a kit JE PISTONS in 80mm
( ration 9.5).

I have two questions:

I would like to know which value of timing advance do i have at 900-1000 RPM for working perfectly ??

which spark plug Bosch do i install in my engine for working perfectly ??

excuse me for my english but i'm french :)

thanks for your answer

regards

Jérôme

Jerome,

What octane fuel will you be using? 95 or 98 RON?

Hi Jerome,

Set total timing to 34 degrees at 6K RPM. Use Bosch W6DC plugs at factory gaps (.032).
