Is there a high performance tranny for b16 A2

I have a b16 A2 and i dropped the transmission once, i have a shit load of power coming out of it and its a y21 transmission, i was wondering if there were any upgrades, or any high performance ones that will stand up to the power, or will this brand new stock tranny i just bought hold up?????

well how much you putting down? cause I really dont think your pushing enough to tear apart your tranny hondas trannys take an assload of power.
