Can be done on 'any' engine. Stock cars have timing optimized for global markets = broad safety limits. Too early ignition will destroy the engine due to more heat and/or because of detonation stresses break bearings, piston rods etc. I guess stealerships havent got bits available for the mod.
Few degrees advance generally increase pwr and can be done safely, however the vehicle isnt for blondies after that... Higher octane gas needed etcetc. The issue is lenghthy, pls educate uself before doing or lettin anybody modify anythin. Couple of links:
