I have a 85 250sx that needs a new motor, will a 85 trx 250 motor be a direct swap into it??

I don't know if they will swap out or not ?, why not just rebuild the '85 250sx motor ??.

i do know the sx motor has alittle more gitty up and go than the reg 250. i'm guessing your wanting to drop in a trx250 fourtrax utility motor in there ?.
