Well..supposedly the ultimate setup is the Si final drive with the ZC gears, in the Si tranny. I read yesterday on the hasport page that none of the axles availabel here in the US will fit the ZC...not even the 90-93 integra axles, but I find that hard to believe. If you can get a ZC with LSD, definently go that route...you won't regret it, just try and get the J-spec axles with the tranny.
Also how much you asking for the ECU's, and why you selling them?
