Trying to make a pt here with general reference. We have seen many vehicles with cheap Chinese made pumps and turbos and am telling ppl to steer clear.

But if u must know, yes there are a lot of copies out there. Serial numbers are your best bet to verify with IHI. I couldn't even walk into Subaru and get hold of a VF34 off the shelf locally in Japan, but outside JDM it is widely avail.

Edit: Jester PM me your serial number and I can send it off to our Japanese office and verify it for ya.
