Audi B5 S4 2.7t JAE RS6 / RS4 Turbos 4644 (High Flow Turbine) w/ K08 THE TUNER Housings Tial Actuators
These are built to following custom specification: The Tuner 08 Exhaust Housings: UHF turbine wheel Billet compressor wheelsJAE Tial MVI 2.5 wastegates/brackets/rods Ceramic coated turbine housings Powder coated compressor covers We've made 650+ WHP on JAE UHF turbos with standard turbine housings, K08 turbine housings are extremely durable and free up back-pressure further Turbine housings alone are over $2k USD from THE TUNER
Note: description below is from JAE, and does not include details regarding K08 "THE TUNER" exhaust housing upgrade, as this is not a normally sold option.
We are pleased to offer our dyno and dragy proven custom specification turbos. These turbos utilize an RS4 compressor housing, RS4 turbine housing or RS6 turbine housing, larger then OEM RS6 compressor wheel and a high flow RS6 turbine wheel.
The turbine wheels allows us to lower back pressure limited by housing sizes which lets the engine breathe easier. The RS4 turbine housing has been shown to make 20psi by 3500 RPM while the RS6 turbine housings makes 20psi by 3800 RPM (mods and engine health will change these characteristics). We have been able to make 500whp on 94+Meth on the RS4 housing and 640whp on E70+Meth on the RS6 housing.
The RS4 turbine housing setup features a full sized backing plate to increase efficiency as well as a 9 blade design which is lighter and flows more to increase spool up and decrease back pressure.
The RS6 turbine housings utilizes a 5x blade design turbine wheel to further decrease backpressure
A benefit to purchasing these turbos is the ability to upgrade just the rear housing to reach a higher power goal.
Turbos are supplied with basic wastegates but we highly recommend swapping to Mamba or Tial to ensure less actuator issues. With heavy springs or ample use of launch control, NLS and RAL expect that the wastegate rod connecting the flap to the lever arm will twist and require adjustment via the wastegate arm.
