with that much HP (wow, that is a LOT) the consensus is that the stock tranny wont hold , perhaps even an STI tranny wont hold. as for a clutch I really doubt a full disk street clutch is going to hang on.
get ready for some 4 puck bucking and possibly dog gears to hold that kind of power.
doesnt sound too streetable for me.
BTW, how you making that much power? was it the Unorthodox Pulley?
