ok, so i saw that advancing the timing on a car can add some quick horsepower. so i was wondering if the timing of a 5S-FE could easily be advanced and what type of effects it would have. thanks for any input in advance

i'd be careful with 16 deg base timing and 87 octane. im running 89 octane with 15deg base and ive had some detonation. never tripped the light, but theres some telltale signs in the exhaust manifold, shiny little bits of aluminum that are from the pistons most likely. a little bit of piston gets blasted loose and cools to the exhaust runner. its enough to make me worry and retard it to 13 base, im doing that tomorrow.
