I would never buy anything from that buddy as my intention was just to know what alternatives they have and my inquiry was very friendly where he as sales guy replied like I would never do. And I have browsed net to see those K27 types, and he told that possible in www I can find those K27s K27HF, K27HFS but they never exist in BW.

So how they would be called if they exist in BW portfolio or did someone else make them?

Technically he is correct. The K27 came in either 7006 as used on the 94 964 turbo S or the 7200 as used on the late 930 and 964 turbo 3.3 and 3.6. Other versions of their turbos exist like the K24, K29 and others.

The K27HF and K27HFS amongst others are hybrids. They were not made by Borg Warner. These were K27's that were modified by outside turbo tuners. I have a K27HF in my 94 turbo and it is a huge improvement over the stock K27 when accompanied by other modifications. Others I have heard who installed them on stock exhaust claimed they hurt the car's performance. In either case not much has been discussed about these lately and many doing newer upgrades are leaning towards Garret and other brands.
