QUOTE (match220 @ Dec 15, 2013 - 1:59 PM)  The alternator on the 4th gen is larger with a higher amp output (not sure of the number right now). I'm running individual coils on my gen3 I bought a gen4 alternator (yes it bolts right on), so at higher RPM i expect there to be more of an amp draw than the distributor with 1 coil. I'm not sure if this is the reason that toyota put the larger alt in though. Why COP should require more amps than distributor? It shouldn't. Each setup requires the same number of coil charge/discharge for a given RPM. The only difference is that the coil charge duty is splitted to 4 different coils. This mean that each coil has more time to cool down between each charge/discharge event and this lead to less wear/coil change. The total energy drawn (power/amps) is the same between distributor and COP. I'm not sure the gen4 alt is bigger because of the COP, who know, maybe the Caldina has more body electrical features than a Celica.
