K03-015 is the KKK part code for the turbo.  The 015 is the variant of the k03 turbo as there's a different ones fitted to different engines with different inlet and outlet arrangements.  You just need one from a b5 passat 1.8t or an audi a4 of similar age with 1.8t.

If you don't want a chinese copy then you're looking at 2nd hand.  Either ebay as Rocket has done there or scrapyards.  They can be had for £50, both the ones I've got were £50.

Keep an eye out on eBay. I looked for a few weeks for this one to come up for sale.

K03-005 is the usual variant from a Passat, but there are a few other variants that fit too.

Avoid the copies unless you're prepared to carry a spare and the tools to swap it. Some are okay, others are only worth their scrap value - even when new. I've seen too many fail now to recommend it, especially when a serviceable secondhand genuine item is less than half the price of a copy.

was thinking of buying one of the copies from ebay and then rebuilding the internals using the parts from a legit K03 i have so i end up with a fresh turbo with a shiny casing.

thoughts?

I wouldn't bother with the chinese copies at all.  None of the parts on them are up to standard.

Exhaust housing on a turbo stay nice and clean and new looking for abpit ten minutes they always end up brown and horrible because of the heat.

By the time you have messed about buying a Chinese copy and a decent genuine used k03
stripped them both down rebuilt them and had it balanced you could probably have bought 3-4 decent used k03s

Been saying this for years, funnily enough, about the same time I met you.

The casings are made from old coke cans and whatever else falls in the shredder. The chinese turbos even fail on Robin, and he's genuinely Chinese, buy an old original and get it rebuilt, much safer bet.
