93 octane will be fine.

I am running 94 octane in my LS/VTEC, which has PR3 pistons. I had the head and block surfaced, so compression is a bit higher.

Of course, the tune is very important. I am running Uberdata, and I modified my old B16A bin, with lots of fuel and not much timing. I also set the timing at my distributor at about 15 degrees. I have no pinging.

EDIT: I should also mention that I just had my brother tune the car with our wideband oxygen sensor, and it was still lean. We had to add a lot of fuel past 7000 rpm, enough that I'm almost maxing out my stock B16 injectors. When I get big cams (only running JDM P30 right now) I'm gonna need some DSM's.

dang...i stuck w/91 here...

 

Yup, we get the good stuff up here in BC. Perfect for boosted engines and high compression N/A engines.

 

jersey has 94 at sunoco. ultra94! you might also want to ask in the Tech Section or All Motor section

 

shouldn't be an issue. i've got the same setup but with stock cams for now and running 92 or 93, depending on where i fill up.
