strongest manual box will be a properly locked awd box from an evo. followed by the awd box locked from a gsr. then you have the 1.8 fwd box from either the proton m21 satria gti or glxi lancer (people say the proton boxes are stonger but the gearbox code is the same thus i don't believe they are as they'll have the same bits inside) and bringing up the rear is the 1.5l fwd box from the pov spec cc lancer
