Size of Stock Turbo

[Kronos]

I have done some research and found that the older model STI has an IHI VF39. Wondering if it's the same on the 15+ STI?

And yes I have used the search function but I have glasses.

Here is a link to cobbs's site that list all the standard turbos.

Looks like the 08-15 STI's use a IHI VF48 turbo while 08-14 WRX's use a IHI VF 52. Also, the 2015 and up WRX's use a Garrett MGT2259S for the new FA/FB engines.

Hope this answers your questions.

IIRC, the STI has had the same "size" turbo for quite a while now. It's mostly design changes (waste-gate, bearings) that improve upon the basic design, while the size stays the same.
