CTS Turbo is proud to introduce the world's first truly bolt-on turbo upgrade for MQB vehicles.
After a long and tedious R&D process, our engineers have finalized this turbo upgrade kit to create a modular package that is capable of producing upwards of 600hp and has the long-term reliability of a genuine Garrett Gen2 GTX turbocharger.
At the heart of our aptly named BOSS (Bolt-On Speed Solution) MQB upgrade kit is a Garrett Gen2 GTX turbocharger, it is installed into a CTS proprietary exhaust housing. The housing is carefully cast and machined to be compatible with any exhaust downpipe and the scroll area was designed to be approximately 0.63AR. This results in very good boost response and eliminates any possible restriction.
Don't be fooled by other manufacturers putting a larger turbo into a stock housing. It is not beneficial, that is why we made our own!
Custom wastegate solenoid bracket and oil/water lines complete this kit to offer simple installation, simple tuning, and problem-free operation.
Proprietary custom molded silicon hoses connect the turbo to your turbo outlet pipe and air intake.
Currently the BOSS turbo upgrade is only compatible with CTS Turbo intake, however, other intakes could be made to work - unfortunately, we cannot provide guidance for installing other manufacturer's intakes.
You can use a CTS Turbo or other billet diverter/blow-off valve. Factory DV is compatible but requires a harness extension. Only OEM or CTS turbo outlet pipe is compatible at this time.

Just wanted to share some love to Harry's euro and their team! Bought parts for my r32 and gti, they never disappoint. Love being part of the euro community in an ever so dominant jdm culture in New Zealand. Looking forward to bringing an rs3 in for tuning :)

I took my BMW to get the downpipe installed. Harry's Euro has done an excellent job. I'm very satisfied with the quality of their work. The staffs are very nice. Highly recommended. 10/10

I've been a loyal customer of Harry's Euro since 2017, and I can confidently say Scott and his team are the best in the game. Not only do they consistently offer the best prices, but the service is always top-notch. Scott is honest, transparent, and always takes the time to explain what’s going on with my car. Whether it's routine maintenance, unexpected repairs, or upgrades, I always know my car is in the best hands. Highly recommend to anyone looking for a reliable, expert mechanic!
Andrew Atkinson
Used Harry's Euro for years owning a Mk6R and now a Mk5 R32. Amazing service and delivery! R32 kit arrived today with some extra goodies! Pleasure to deal with the team!
Mark Barber
Hands down the best Euro shop in Auckland. They've looked after 2 builds of mine, and the parts, service and expertise has been top notch.
Marc Graham
Harry's Euros delivered platinum service from start to finish. The quality of the products is excellent, and the install experience was smooth and professional. If you want a lower cost acceleration boost ask Scott about a Pedal Box! Huge difference and very simple to use.
Quinn Ashby
Got some basic servicing and a Stage 2 transmission tune done today to match the ECU tune. The team was really helpful with information, communication via email, fit me in quickly, and offered fair, industry standard pricing for a specialised shop. Highly recommend, and I'll definitely be back!
Hayden Lawrence
Great service. Needed a replacement driver's side mirror glass for our old GTI. Harry's Euro had it in stock for a good price and shipped it next day. Very pleased with the transaction and will happily recommend and use them again.

Been Working with Harry's Euro for almost 3 years now and I can highly recommend any auto-work or performance upgrades to be done by these guys. I've had my previous car and my current done by the team cheers to Scott and the boys for the work 🍻
