Audi R8 ALPHA Twin Turbo Kit
Complete your own R8 turbo build with the proven AMS quality hardware as the foundation. You customize your turbo build and tuning to your specifications and needs. We make it easy for you by providing the R8 specific turbos, intercoolers, piping, exhaust, heat exchangers, and ancillary components for you to base your own build on. Simply add your choice of engine (ECU) and transmission (TCU) tuning, boost control solution, fuel system, and engine and transmission builds (if necessary depending on your desired level of horsepower) to complete your own package.
Choose a Turbo Size That Works For You
Variety is the spice of life. We know that every R8 owner has different goals in mind for their vehicle, which is why we offer a wide selection of top-of-the-line Garrett G-Seriews turbos that support every use case from a simple show-car all the way up to a competitive drag racer. From a basic bolt-on build like in our ALPHA 9, to a fire breathing 3000 HP competitive race car like the ALPHA 28, we’ve got you covered.
G35-1050 — Entry level 68mm twin turbo build from 900-1200 WHP. Standard in our ALPHA 9, 10, and 12 packages.
G40-1150 — Stepping up to larger 71mm turbos capable of 1600 WHP. Utilized in our ALPHA 14 and ALPHA 16 builds.
G42-1200 — 73mm inducer found in our ALPHA 20 package. Capable of cracking the 2000+ WHP barrier.
G42-1450 — Our ALPHA 24 package features these 79mm turbos and easily pushes power up to the mid-2000 WHP range.
G45-1600 — These 80mm turbos are found in our ALPHA 28 package and are capable of 2800+ WHP and 6 second quarter mile passes.
Our team has gone the extra mile to develop innovative new solutions to problems found when adding forced induction to the 5.2 FSI V10 engine found in the Audi R8. One of the things we saw during the development phase was a substantial air leak at the intake manifold flange due to the now positive air pressure within the manifold. To solve this, we developed a beautifully machined and anodized aluminum ring which fits around each intake runner gasket to provide additional sealing pressure. We chose to engineer and machine an elegant solution while competitors take the easy way out and use silicone to essentially glue the manifold pieces together.
Titanium Exhaust Upgrade
Exceptionally lightweight and extremely strong, titanium is the ultimate material for supercar exhausts. Not only is the aesthetic improved, but titanium piping offers a uniquely exotic exhaust note that is sure to turn heads. Where others are charging $10,000 or more for custom titanium exhaust options, our AMS ALPHA Twin Turbo Kit Titanium Exhaust is included as standard, at no additional cost. The AMS titanium exhaust is available in a number of different shapes and sizes, including a center exit for the 2020-2024 R8 with G40, G42 or G45 turbo kits.

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 :)
Greg Davies

Sebastian Ramirez
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 🍻
