look for a h22 tranny..there both jdm...M2B4 is lsd and M2A2 is non-lsd
usdm h22 tranny will say M2F4 and does not have lsd but has a shorter 5th gear

accord tranny to me is still to long of gears even for boost, h22 is like a gsr tranny to me
still good for boosted setup, accord tranny would be good if you had maybe 400whp+
