it's not HP that kills them but torque

the torque convertor is the weak link and technically not rated for any more torque than the zetec is putt9ing out (135 ft lbs at the flywheel is what its rated for)

after that the clutches will go...they tend to hold abt 150 fwhp, like you said

Lentech and Performance automatic will either supply the parts for a rebu9ild yourself or they'll send you a whole transmission, lentech has one or two levels higher strength above the PA unit, although they both make one that hsould be more than adequate for mild FI and nitrous use (anything pump gas)
