Pistons Change
I have a Porsche 911 Sc 1982. I want to change Pistons 9.3 to 10.5 compression. Can I use 93 oct. gasolie with compression 10.5?

Jose:
Nossir,.....93 octane gas with 10.5:1 requires twin-ignition.

Try not, Do or Do not

I whole-heartedly agrees.
With the CIS injection that came with the 82 SC 9.3:1 is almost too high. 10.5:1 on 93 octane is dreaming even with twin plug (but so many of us have these kinds of dreams).
