Okay... I reset timing to 2 degree advance... And there's no detonation. I suppose 93 octane is good enough! haha
Compression numbers were fine... 230-236 all the way around with cylinder 4 down to 218 because of a leaky valve seal.
if memory serves me right, anyways.

cam timing is stock, b16a1 cams may need to be swapped out for something beefier like ctr's or skunk stage 2's or whatever will work with itr vavlesprings/retainers.

Plugs are a color I would call "textbook maroon" ;-) haha they look great.
