FAQ
Is 0.88 A/R a good street choice?
Yes—0.88 A/R on a T4 divided housing provides a strong balance of spool and flow for many S300 builds.
Will this bolt to my factory manifold?
Only if your manifold is T4 divided. Many OE manifolds are T3 or use different flanges. A T4 divided manifold is required.
Does this fit all S300 turbos?
It fits S300/S300SX3 CHRAs that match the turbine wheel family for this housing. Always confirm wheel size and step before ordering.
Wastegate provision?
This housing is typically non-wastegated. External wastegate use depends on your manifold and build goals.
Do I need different downpipe hardware?
Possibly. Verify your current outlet (clamp and flange style) to ensure compatibility with your existing downpipe.
