Maximize your S400 T6 based turbocharger's potential with our T6 Turbine Housings! For 96/88mm S400's, choose between a quick spooling T6 divided 1.15 or a 1.32 for more breathing room. If you have an FP92 based unit such as our FP8892, the 1.58 is a great choice for larger displacement or big emap reduction while the 1.32 is our standard setup.
