the othere day i found the exhust wheel of the turbo sitting in the cat...... so im guessing my car has had a new turbo put on it.....i have an R32 GTS-T

all i can see on the turbo is 926 on the intake side of the turbo......
or maybe it was 629....

how can i tell what my turbo is without taking it out?
thanks.

exhaust wheel from the old turbo was sitting in the cat? that was nice of them to leave it there 4 u!!
