hey guys i have a jdm b16a tranny with factory LSD..im looking into rebuilding it, because the syncros are pretty much done. i was wondering will the LS or GSR 5th gear just install right in..even though is has the LSD, since its not a USDM tranny? i'm looking to do a real closer gear ratio set up..mostly for acceleration..but want the LS or GSR 5th for highway use. any help is appreciated.
