What it is
This is a brand-new, genuine Borg Warner turbo, part number 53039880207, factory-known as "CR170" or "CR140 Stage 3." It's OEM equipment on the European-spec 170hp CBBB-engine Mk6 VW Golf, Jetta, and Beetle, cars not sold in the US market.
Critical fact, this is NOT a plug-and-play US-market part
This exact turbo, in its factory Borg Warner trim, is not listed by Borg Warner as fitting any US-market vehicle. It is listed on this page for reference purposes only. Some people use it as an incremental upgrade over the US-market CBEA/CJAA CR140 turbo, and it will mostly install in that turbo's place, but it is explicitly not a direct drop-in replacement, despite sometimes being informally called "plug and play" elsewhere.
If you want an actual drop-in CBEA/CJAA upgrade turbo
KermaTDI sells a separate, modified version of this turbo specifically built to be a true drop-in replacement for CBEA/CJAA cars: the KS3 CR170. That is the correct product if you want a bolt-in upgrade without extra fabrication or troubleshooting.

Common questions
Is this the right turbo for my CBEA or CJAA Golf/Jetta? Not as a guaranteed drop-in, this exact part isn't rated for any US-market car. If you want a true bolt-in CBEA/CJAA upgrade, order KermaTDI's KS3 CR170 instead, which is specifically modified for that fitment.
Can KermaTDI help me install this in my US car? No, KermaTDI explicitly does not provide technical support or installation help for this part in US-market vehicles, since it's not intended for that application.
Can I return this if it doesn't fit my car the way I expected? No, all sales of this turbo are final, with no refunds or exchanges.
What car was this turbo originally built for? The European-spec 170hp CBBB-engine Mk6 VW Golf, Jetta, and Beetle, not sold in the US.
