New Replacement Compressor Housings for Holset, Garrett and BorgWarner Turbochargers
The compressor housing is the cold-side cover that channels air from the intake into the compressor wheel and out to the charge-air system. It defines the turbo's airflow geometry — the inlet diameter, the volute shape, and the outlet angle all affect how much air reaches the engine and how efficiently it gets there. We stock brand new compressor housings for Holset, Garrett and BorgWarner turbochargers across Cummins, CAT, Detroit, Volvo, PACCAR and Ford applications. Each housing is manufactured to OEM-spec dimensions — bore diameter, scroll profile and bolt pattern — and matched by the turbo model and part number. Shops that rebuild turbos in-house source individual housings when the original is cracked, corroded, or worn past tolerance. All units ship from US stock with no core charge.

A cracked or eroded compressor housing is one of the most common reasons a turbo rebuild cannot reuse the original cold side. Dust ingestion scores the bore, pressure cycling fatigues the material, and corrosion attacks the casting over time. A new housing restores the air seal and dimensional accuracy that the compressor wheel needs to operate at peak efficiency.
Every compressor housing we ship is manufactured to the same bore diameter, scroll profile and outlet geometry as the original. Dimensional accuracy on the bore is critical — even tenths of a millimeter of clearance change affect compressor efficiency and surge margin.
Compressor housings vary by turbo model, compressor wheel size and outlet configuration. We match by the turbo model (HE300VG, HE400VG, GT3782V, S400SX4, etc.) and the OEM part number to ensure the housing fits the specific CHRA and wheel combination in your rebuild.
We stock housings for Holset HE and HX series, Garrett GT and GTP series, and BorgWarner S300, S400, K03 and B2UV families. One source for the most common turbo platforms in heavy-duty and light-duty diesel.
Select compressor housings include ported shroud or anti-surge features that extend the compressor map and reduce surge at low flow conditions. These features are built into the casting — they are not machined secondary modifications.
Replacing only the compressor housing during a turbo rebuild costs a fraction of a complete turbo replacement. If the CHRA, wheels and turbine housing are in spec, a new compressor housing restores the cold side without replacing parts that do not need it.
One-year warranty on every compressor housing. See the warranty page.

WHY CHOOSE US
We verify turbo model and part number before dispatch, hold inventory on a US shelf, and support rebuild shops with the parts they need to keep turbo work in-house. More about our company and quality process.
Replace the compressor housing when it shows bore scoring from foreign object ingestion, cracks from pressure cycling or impact, corrosion that has pitted the scroll surface, or when the bore has worn past the tolerance needed for proper wheel-to-housing clearance. If the bore is scored deeply enough to feel with a fingernail, the housing should be replaced.
By turbo model and part number. The compressor housing is specific to the turbo model (for example, HE300VG, HE400VG, GT3782V) and sometimes to a sub-variant within that model. The part number on the original housing or the turbo's dataplate identifies the correct replacement.
A ported shroud housing has machined slots or openings near the compressor wheel inlet that recirculate air at low-flow conditions to prevent surge — the condition where airflow reverses through the compressor and causes boost instability. Ported shroud housings extend the usable operating range of the compressor map.
In some cases, yes — if a larger compressor housing is available for the same turbo frame and CHRA. The housing must match the compressor wheel diameter and the bearing housing bolt pattern. Contact us with your turbo model and we can confirm whether an upgrade housing is available.
All units are 100% brand new. No rebuilt or reconditioned housings. OEM-spec dimensions, one-year warranty.
Yes. Turbo rebuild shops order compressor housings as regular inventory. Consistent wholesale pricing from US stock. See the wholesale page.
The compressor housing is the cold-side shell of the turbocharger — it directs ambient air into the compressor wheel and channels the compressed air out to the engine's charge-air system. Understanding its role, failure modes, and replacement criteria helps rebuild shops make the right sourcing decisions.
The housing serves three functions: it positions the air inlet concentric with the compressor wheel, it forms the volute (scroll) that collects compressed air and converts velocity into pressure, and it provides the outlet flange or pipe connection to the charge-air cooler. The geometry of the scroll — its cross-sectional area, its rate of expansion, and its tongue position — directly affects the compressor's efficiency and surge margin.
If the CHRA (center rotating assembly), turbine housing and wheels are all within spec, replacing only the compressor housing saves significant cost. A typical compressor housing costs a fraction of a complete turbocharger. Rebuild shops that perform in-house turbo work routinely stock common compressor housings to turn rebuilds faster without waiting on complete turbo assemblies.
