Garrett G30 Turbine Housing Kit O/V T3 / V-Band 0.83 A/R (Reverse Rotation)

If you're building a custom turbo setup or looking to fine-tune your existing Garrett G30 turbocharger, this turbine housing kit is a key component. This specific housing features a T3 inlet flange and a V-band outlet, offering a versatile connection for many exhaust systems. The 0.83 A/R (Area/Radius) ratio is chosen to balance quick turbo spool-up with high-end power potential, making it a popular choice for builds aiming for a broad powerband.

Crafted from durable cast iron, this housing is built to withstand the extreme temperatures and pressures found in forced induction applications. The reverse rotation design is specific to certain G30 turbocharger models, ensuring proper fitment and function. This kit includes the turbine housing itself, ready to be bolted onto your compatible Garrett G30 turbocharger. Proper installation involves ensuring the V-band clamp is securely tightened and that the housing is correctly oriented with your downpipe.

When selecting a turbine housing, the A/R ratio significantly impacts how your turbocharger performs. A lower A/R, like this 0.83, generally leads to faster spool-up, meaning your engine reaches boost pressure sooner. A higher A/R would favor top-end power at the expense of slower spool. This particular ratio offers a solid compromise for many performance-oriented builds. Please note that this part is not CARB approved and cannot be shipped to California.
