I'm considering an engine swap myself, but I'm just concerned if the ZXT CV axles can reliably handle 300+ hp/tq without snapping.

from what i hear.... the CV's are VERY strong. the s30 guy with the GN swap doing rediculously hard launches and im sure way over 300ft/lb or hp is using an R200 rear end with stock CV axles and a modernmotorsports adapter. here yah go yah scaredy cat read for yourself. but looks like he is switching to corvette stuff back there now.... but w/e he still ran them
