Garrett GT42/42R/GTX42R Gen I Turbine Housing Kit Div T4 / V-Band 1.44 A/R (Mid Frame)

This is the Garrett GT42/42R/GTX42R Gen I turbine housing kit, designed for mid-frame turbochargers. It features a 1.44 A/R ratio and supports both T4 and V-Band exhaust manifold connections, giving you flexibility when building or upgrading your forced induction system. This housing is a key component for managing exhaust gas flow into the turbine wheel, directly impacting spool characteristics and overall power output.

The 1.44 A/R (Area/Radius) ratio is on the larger side for this frame size, which generally means it's optimized for higher horsepower applications and helps to reduce backpressure at higher RPMs. This can lead to improved top-end power delivery. The cast iron construction is well-built to handle the extreme temperatures and pressures associated with turbocharging. The dual inlet design, accommodating both T4 flanged manifolds and V-Band clamps, offers a unique installation advantage, allowing it to be adapted to a wider range of custom exhaust setups without requiring extensive fabrication.

When installing this turbine housing, ensure you have the correct mating flange or V-band assembly for your exhaust manifold. It's also crucial to properly torque any associated hardware to prevent exhaust leaks, which can significantly impact turbo performance and efficiency. This kit is intended for performance builds where precise control over exhaust gas flow is critical for achieving desired power levels.
