i hope u didnt buy that bov. i dont have real experience with that one, i have the new hks ssqv. when i was shopping for a bov i looked to a few guys from the toronto supra club. i ran accross that one and they all told me it was crap. and yeah, the casing is a hard plastic and the internal parts tend to tear very easily. not too sure how much boost it can hold but i'm not thinking much, let alone the reliablity factor to it, it is alot older and there is a newer model thats been relatively unchanged for a while now. good luck!
