Hi! I have a sunny n13 Hatch and I would like to make It a bit more powerful. I cant find much info about performance upgrades for the Ga16i. I already have iridium spark plugs, performance spark wires and 2.3" de-cated stainless steel exhaust. I Will change ignition timing to 10. Next step Will be a machined flywheel but I don't know How much weight should I take from It... I also want to install 2 Weber 36 or 40 carbs with custom manifold but I don't know what is the best Air efficiency design for the Engine. Also heard about a eurocam but I don't have any information related to Power gains from the dealer, neither where to get reinforced Valve lifters and heavy duty cam Springs. Any information from someone who has done the same Will be Very helpfull. Regards!
