I know the car needs to be put on the dyno to fully tune, and I may not need to advance it that much.

BUT....for ***** and giggles. How much can you safely advance the timing on an internally stock B16A with 93 octane gasoline? Race fuel?

I'm getting ready to take it to the dyno in about a month, so I'm just kinda curious right now.

 

No need to really run more then 18 degrees. It was proven that you can on a stock motor, but does nothing after 19 degrees. 21-24 was tested. Actaully didn't knock believe it or not, but made no change on the dyno. I would run 16 degrees +/- 2 degrees.
