turbo

hello,i used to own a 96 sti ra and after a few months the crankshaft
fooked up.I still have the old engine out of the car but what i am
wondering is, when i bought the car the owner told me it had a bigger
turbo fitted,could some of ye lads tell me is it true or was he just
talking piss.Heres some numbers off it,
IHI turbo
SPEC VF10 8911
RHB52 D1033A
Thanks for help.

I think this turbo came on the USDM Legacys.

Defo a legacy turbo, Think they rated for 250hp. Don't know enough to say if thats an upgrade over the Standard Impreza Turbo
