is this turbo too big for my car

the inducer/exducer numbers are mixed up. but anyway,

thats a big turb, with a small exhaust housing.

for reference to sizes here

GT3582R commonly refered to as a GT35R is an 82mm exducer, 61.4mm INDUCER. the turbo you mentioned would be considered roughly T66 on the street. aka BIG, really BIG for a b16.
