The best LS twin turbo setup depends on matching the turbos, headers, oil supply, and available space to the engine and vehicle. The POWERGO MOTORSPORT headers are the most directly LS-focused choice, while the ICT Billet adapter plate addresses oil-feed plumbing. The other listings offer turbo components, but their specifications and fitment need careful verification before use in a twin-turbo build.
| Product | Best For | Key Consideration |
|---|---|---|
| POWERGO MOTORSPORT turbo headers | LS-based custom turbo builds | Confirm engine and chassis fitment |
| maXpeedingrods GT35 turbo kit | Buyers comparing a general turbo package | Listed as a turbo kit, not a twin-turbo pair |
| Twin Turbo Turbocharger Set | Buyers checking turbo replacement numbers | Verify part numbers and LS application |
| AParts High HP Turbo Kit | Custom, higher-output turbo projects | Broad fitment claims require confirmation |
| ICT Billet oil-feed adapter plate | LS oil-feed plumbing and sensor ports | Not compatible with several listed oil pans |
POWERGO MOTORSPORT LS Turbo Headers
These up-and-forward-facing headers are designed for LS-based small-block V8 engines, with listed engine applications including the LS1, LS2, LS3, and LS6. The product states that the headers can be used for single- or twin-turbo builds, making them the most directly relevant exhaust component in this selection.
The tubes are fully mandrel bent and made from 16-gauge, 1.5-millimeter 304 stainless steel. This option is best for builders who need an LS-oriented header starting point and are planning a custom turbo installation. Choose it if forward-facing turbo placement suits the project. Caution: The listing does not establish fitment for every LS engine, chassis, or accessory arrangement, so confirm clearances before purchase.
maXpeedingrods GT35 Turbo Kit
This listing describes a GT35 turbo kit with a T3 exhaust inlet flange, a four-bolt, 3-inch exhaust outlet, and a 0.63 A/R turbine. It also specifies an intercooler measuring 27 by 7 by 2.5 inches and oil feed and return lines. The stated engine range is 2.5 to 6.0 liters, but the listing says the turbo is not vehicle-specific.
This is best for buyers comparing a general turbo package for a custom engine project. It is not presented as a matched pair, so it should not be treated as a complete twin-turbo setup by itself. Caution: The seller notes that modifications may be required, installation instructions are not included, and buyers should verify compatibility and available space before ordering.
Twin Turbo Turbocharger Set
This listing is identified as a twin turbocharger set and provides a long list of interchange numbers, including 743279-series and 752538-series references. It describes the units as having durable construction and says they are intended to improve acceleration and power output.
This option is best for a buyer whose existing turbo application can be verified against the listed interchange numbers. The listing does not specify an LS engine application, turbo dimensions, or detailed mounting information, so it is not possible to confirm a direct LS fit from the supplied details. Caution: Match the required part numbers and specifications before considering this set for a custom LS installation.
AParts High HP Turbo Kit
AParts lists this kit for several engine families and states that it can also work for twin-turbo applications on SBC and LSx engines. The listing describes a turbocharger made with aluminum and iron components and mentions a precision-machined housing, compressor and turbine wheels, and a claimed power capability of up to 600 horsepower.
This is best for custom-build shoppers who want to investigate a broadly advertised turbo option for an LSx project. Its twin-turbo claim makes it relevant, but the listing does not provide enough configuration detail to establish that one kit includes all parts needed for a complete two-turbo installation. Caution: Confirm the exact included components, engine fitment, and required modifications with the seller.
ICT Billet LS Twin Turbo Oil Adapter
This billet adapter plate seals an oil port in the oil pan above the oil filter and provides two 1/8-inch NPT ports. The ports can be used for turbo oil-feed lines or sensors, so the part can support plumbing for a twin-turbo layout. ICT Billet states that it is made from aerospace-grade, USA-produced billet aluminum in Wichita, Kansas.
This is best for LS builders who need two oil-port connections at the plate location. Its defined purpose makes it a useful plumbing component, rather than a complete turbo kit. Caution: The listing excludes GTO front-sump, dry-sump LS7 and LS9, and LS4 oil pans; confirm the oil-pan type before choosing it.
Buying Guide: How to Choose LS Twin Turbo Parts
Does the listing include one turbo or two?
Check whether a product is a complete pair, a single turbo, or a supporting component. A single turbo kit may supply useful parts for a custom build but does not automatically provide two matched turbos or the plumbing and fabrication needed for a twin setup.
Will the headers fit the engine bay?
Confirm the engine family, header orientation, chassis space, and clearance for accessories and other components. Up-and-forward-facing headers can inform turbo placement, but the listing alone cannot confirm fitment in a particular vehicle.
Are the oil connections appropriate?
Plan oil feed and return routing for both turbos. Check the fitting type, port count, and oil-pan configuration. The ICT Billet plate has two 1/8-inch NPT ports, but its stated oil-pan exclusions are important.
What should be verified before ordering?
- Confirm engine and vehicle fitment with the seller or a qualified installer.
- Compare turbo part numbers, flange details, and outlet dimensions with the planned system.
- Check what components are actually included; do not assume a listing is a complete twin-turbo package.
- Account for space, custom fabrication, and professional installation where needed.
Frequently Asked Questions
Can these headers be used for an LS twin-turbo build?
The POWERGO MOTORSPORT listing says its up-and-forward headers are for LS-based engines and can be used for single- or twin-turbo builds. Confirm fitment and clearance for the specific vehicle.

No. The listing excludes GTO front-sump, dry-sump LS7 and LS9, and LS4 oil pans.
Does the Twin Turbo Turbocharger Set specify LS compatibility?
The supplied product details list interchange numbers but do not identify an LS engine application. Verify part numbers and specifications before purchase.
