Garrett 740902-0087 G30 Turbine Housing Kit 0.83 A/R V-Band / V-Band

Vehicle Fitment

• Universal -- Garrett G30 standard-rotation supercores (G30-660 / G30-770 / G30-900)

Fitment Notes

• Turbine housing only; pair with a compatible G30 supercore and matching turbine wheel
• Standard rotation; open volute (no internal wastegate)
• V-band inlet and V-band outlet required on the manifold and downpipe
• Verify space/heat shielding for stainless housing operating at high EGT

Features

• 0.83 A/R sizing balanced for quick spool and strong top-end on 2.0-3.5L builds
• Stainless-steel cast housing for durability and heat resistance
• V-band in/out simplifies clocking and packaging in tight bays
• Optimized volute geometry for efficient turbine energy extraction
• Compatible across G30-660/770/900 standard-rotation supercores
• Supports high exhaust temperatures typical of performance use
• Corrosion-resistant materials for long service life
• Engineered for external wastegate control to minimize boost creep

Product Description

Garrett 740902-0087 is a stainless G30 turbine housing engineered for standard-rotation G30 supercores. Its 0.83 A/R sizing delivers a strong balance of response and peak flow, making it a versatile choice for 2.0-3.5L performance applications that need quicker spool without sacrificing top-end power.

The V-band inlet and outlet simplify installation, allow precise clocking, and reduce leak points, while the open-volute design is intended for use with an external wastegate for robust boost control. Built from corrosion-resistant stainless, this housing withstands sustained high EGTs and harsh environments common to street/track builds.
