    Not sure on the accuracy but here is some info.

    Wiki link

    Seems like just getting a 2nd gen 3sge give you 30 hp on it's own. Not a bad upgrade if it can be had reasonably.

    I would think a stand alone ECU would give the best gains in general.

    The 2nd gen had more aggressive cams and fuel maps. It also trades TVIS for ACIS. So if you use the electronics from the 2nd gen then you'll have to do away with TVIS or use something else to activate it.

    The best upgrade for the first gen is a JDM ECU.

    Honestly, it's not worth the money and effort to change out electronics when you can just buy a used JDM ECU and get 30hp.
