Hybrid Turbocharger 400ARS for 1.750TBi engines for applications up to 400hp
Turbo Upgrade: This option requires to ship your stock K04 turbocharger and it is mandatory that your turbo has no cracks or damage in the turbine and compressor housings. Your order will be processed after we receive and check your turbocharger if your cartridge is damaged there is an additional cost for replacing it with a new one, in this case, you will be informed via e-mail or phone call. The hybrid 400ARS turbocharger that you will receive has the following brand new parts: large billet compressor wheel, large turbine wheel. The compressor and turbine housings are being thoroughly checked and then are machined with the appropriate tolerance in CNC machines in order to work with the large wheels.
Wastegate Exchange: with this option, if your stock wastegate is fully functional it will be modified with stiffer spring.
After lots of dyno and road tests, we managed to create a new turbocharger system suitable for daily use thanks to the selected turbine wheel - shaft that ensures optimal response and reduced backpressure.
We machine and manufacture all parts in our CNC HAAS milling VF4 4 -Axis machine and our CNC HAAS turning SL20 3 - Axis machine, made in the USA, with 0.001mm accuracy. The turbocharger calibration is made in a machine, constructed in Italy, with 0.8-1.0 G Force accuracy.
We engineer, design, and manufacture all our products according to the ISO 9001:2008 certification.
The compressor wheel is manufactured out of solid (billet) high-quality aluminum. The upgraded "gen 2" compressor wheel is much larger than the stock unit and thus has greatly improved flow characteristics while maintaining low weight due to its construction and alloy.
The turbine wheel and shaft are much larger than the stock as well. This improves the turbine's exhaust gas flow and reduces backpressure. The reduced back pressure allows for more ignition timing and an overall broader torque curve. The 400ARS is a bolt-on for power and torque gains with the appropriate supporting mods.
The design of the wheels might change due to product upgrades.
