Hi, just curious since new 86 come standard engine compression ratio 12.5:1 with standard fuel ron 95 and above, hence was wondering our good old 4AGE from 1st-gen till last, can we just shave off head, block, thinner gasket to do the same?

wow...targeting 12.5 compression ratio...interesting idea...
but with our beloved 4ag ancient fueling system...i have some doubt...err...actually not "some"...its more like will it work at all...
Fuhhh..otai in da house. glad can read your post here.
probably Toyota already prepare a lot of tuning tables for this new 86...to cater various fuel type and emission regulation...
Well actually someone posted saying that the 86 requires RON 98 as per the fuel lid sticker... don't know how true is this but UMW didnt put any notice on RON requirements for the 86
