The XS-POWER Version III LSX T4 Top-Mount Turbo Manifold System provides a foundation for building a custom single-turbo GM LS-powered vehicle. The system combines an LS-series turbo header/manifold arrangement with a crossover pipe that routes the exhaust toward a centrally positioned top-mount T4 turbocharger.
XS-POWER developed this configuration for builders who want to bring a single T4 turbo setup to LS1, LS2, LS3, LS6, LSX and related LS-family engine swap projects without starting the hot-side fabrication completely from scratch.
This is the Version III upgraded configuration and is constructed from 321 stainless steel with a T4 turbo mounting flange and 44mm external wastegate flange.
The XS-POWER Version III LSX turbo manifold and crossover system is manufactured from 321 stainless steel for performance exhaust and turbocharger hot-side applications.
This material specification makes the system particularly suited to the elevated exhaust temperatures encountered in turbocharged LS applications.
The system uses a T4 turbo flange in a top-mount configuration, providing a starting point for a wide range of custom LS single-turbo builds using a compatible T4-flanged turbocharger.
Turbocharger dimensions, compressor and turbine housing size, orientation and surrounding engine-bay clearance must be considered when selecting the turbocharger for a particular installation.
The Version III configuration incorporates a 44mm wastegate flange for use with a compatible external wastegate. Wastegate selection, spring pressure, boost control and final routing should be matched to the complete turbo system and engine combination.
This system is intended for custom turbo builds based around the GM LS engine family. Common search and build applications include:
Engine compatibility does not automatically guarantee chassis compatibility. LS swaps vary significantly depending on engine mounts, accessory drive, steering, suspension, transmission, oil pan and engine placement.
This style of LSX turbo system is commonly considered by builders working with Camaro, Pontiac, S10, C10, Chevelle, Nova, Impala and other LS-swapped performance projects.
These vehicle names describe common LS swap and custom fabrication applications; they should not be interpreted as guaranteed direct bolt-on chassis fitment. Every swap should be checked for physical clearance before final installation.
The system includes the crossover pipe required to route exhaust flow toward the single top-mounted turbocharger.
The crossover provides the basic routing for the LS single-turbo configuration, reducing the amount of hot-side fabrication required compared with constructing an entire turbo manifold and crossover arrangement from raw tubing.
Deep-sump oil pans can interfere with crossover-pipe routing. If your LS swap uses a deep-sump oil pan, substantial crossover modification may be required.
Check oil-pan depth, engine position and crossover clearance before installation. Because LS swaps vary considerably from vehicle to vehicle, some modification may be required for your specific combination.

This is a performance fabrication / LS swap product. It should not be treated like a stock replacement exhaust manifold.
Minor modifications may be necessary depending on the exact vehicle and swap. Builders should verify:
- Engine position and engine mounts
- Oil pan depth and shape
- Steering shaft and steering-system clearance
- Accessory drive configuration
- Transmission and bellhousing clearance
- Suspension and crossmember clearance
- Turbocharger dimensions and orientation
- Downpipe routing
- Wastegate and dump-tube routing
Professional installation and fabrication experience are strongly recommended.
