This 91mm is currently our largest S400 frame turbo offering! Paired with the 92x102mm turbine wheel it makes a great combo for either a drag dedicated 5.3LS or a street 402ci motor. All depends on your application and supporting mods. If you're looking at this listing it means your looking to make 1000whp+. Fully turned up this will make 1400-1500whp with the right fuel and supporting mods. If you're unsure what size turbine housing to go with you can call us to discuss or you can be comfortable knowing we have a 90 day turbine housing trade in program. What that means is if you think you could sacrifice some spool for more top end, or the other way around, we will exchange the housing you have for the one you want. All you have to pay is the shipping back and forth. For better overall performance in your gasoline application please select the 9 blade turbine wheel option. In a gasoline application the 9 blade will spool quicker and will make less back pressure. For Diesel we recommend staying with the traditional 10 blade design. Please keep in mind the 9 blade turbine wheel for the 92 x 102mm wheel is only available in the BALL BEARING configuration. If you would like bigger we also have a huge 99 x 109mm turbine wheel available! this is the largest offering in the S400 platform.
