this week my motor will finally be done. i had it bored out to 84mm and i'm using 11.8:1 pistons. now i live in VA were we have 93 octane (about 2 and some change a gallon), but i'm moving back to SoCal in 40 days. now i remember back home the highest we had was 91 octane (i heard somewhere like 2.50 a gallon). now is my motor gonna be safe from blowing up? now i know it's all about the tuner and a/f ratio. but will 91 octane be sufficient enough for my daily driver to be driven safely?

yah you should be cool as soon as you get down there just get it tuned for 91 octane

 

you're going to have to get your motor detuned for 91. good luck.

 

alright cool. thanks for the info.
