first off, for a replacement alternator, since a obd0 b16 was never offered in america, should i use a 90 integra alternator, or a 94 Del Sol VTEC alternator? the vehicle this is going in is a 89crx si, and the swap didn't come with an alternator. the fuel injectors on the b16, are they the same as those on my crx? i ask because one has a large crack on the head of the injector, and i'm fairly certain that both injectors are the same.then lastly, the exhaust manifold that my swap came with has only the one o2 sensor bung near the cat, not the two in the collectors of the primaries, where, if anywhere, could I pick up the correct manifold for my swap? I've looked on ebay quite a bit, and never has one surfaced.
