Porsche LS swap kits—how CPE does it

A Porsche LS swap kit at CPE is not a mystery box—it is a set of Porsche LS swap parts we design, test, and manufacture in the United States to work together on real cars. All CPE Parts Are Made in the U.S.A. Whether you are assembling a DIY Porsche LS conversion or comparing options before an in-house build, shop by subsystem—Engine Mounting & Transaxle Adaption, Wiring & Integration, Clutch Kits & Flywheels, and Ancillaries (Induction, Oiling, P/S, & A/C)—and match components to your chassis and drivetrain.

We cover the same Porsche platforms featured on our home page: 996 and 997, 986 Boxster, 987 Cayman and Boxster, and 911 (964 / 993). Explore in-house platform overviews for scope and project fit, then use the categories below to pull the Porsche LS swap parts your build needs from our online store.

Engine side, our ecosystem is built around Gen 3 and Gen 4 LS families. Harness-related offerings assume a 58x reluctor configuration. In-house programs often emphasize LS3 and LS7 combinations—the same constraints guide how we recommend Porsche LS swap kits for the street, track, and road-trip cars we support.

LS swap vs LS conversion — vocabulary at CPE

Customers search Porsche LS swap kit, Porsche conversion kit, Porsche engine swap, and LS conversion kit interchangeably. On this site, those phrases point to the same engineering problem set: packaging an LS-based V8 into a Porsche chassis with correct mounts, cooling, harnessing, fuel, and torque transfer into the factory-style transaxle path we support.

If you are comparing Porsche V8 swap options, our focus is GM LS-family integrations paired with CPE U.S.-made hardware—see the LS conversions & swaps hub for how in-house and DIY programs relate.

This is a summary for shopping orientation. Platform pages and consultation confirm what applies to your car.

Chassis LS generation (parts) Harness / reluctor Transaxle note
996 / 997 Gen 3 / Gen 4 (DIY parts); in-house often LS3 / LS7 58x required for CPE harness path Manual transaxle retention; see FAQ
986 / 987 Gen 3 / Gen 4 (parts scope varies) 58x for harness-related packages Mid-engine packaging—confirm project fit
911 964 / 993 Gen 3 / Gen 4 (parts); in-house often LS3 / LS7 58x for harness-related packages 911-specific driveline planning

Installation confidence & support

A Porsche LS swap is major work. CPE publishes a practical 996/997 DIY walkthrough, a growing library of Porsche LS swap guides (996, 997, cost, cooling, transmission topics), and a detailed FAQ on tools, timelines, and what we do not support.

Not sure which Porsche LS swap subsystem to buy first?

Start with mounting & transaxle adaption matched to your confirmed manual gearbox plan, then wiring & integration (verify 58x), then clutch & flywheel, then ancillaries for induction, oiling, power steering, and A/C. If that order feels unclear, stop and email—we prefer one clear plan over a cart of mismatched pieces.

FAQ

Porsche LS swap kits & parts

What is included in a Porsche LS swap kit from CPE?

CPE does not sell one generic boxed kit for every chassis. We offer engineered Porsche LS swap parts—Engine Mounting & Transaxle Adaption, Wiring & Integration, Clutch Kits & Flywheels, and Ancillaries (Induction, Oiling, P/S, & A/C)—all made in the U.S.A. Combine them for your platform, engine, and transmission plan. The CPE store is organized by those systems so you can assemble the right Porsche LS swap kit for your build.

Which LS engines do CPE Porsche LS swap parts support?

CPE kits and parts support Gen 3 and Gen 4 LS combinations. Our harness-related packages require a 58x reluctor wheel (standard on Gen 4). In-house builds often center on LS3 and LS7. The same engineering informs U.S.A.-made Porsche LS swap parts for DIY and pro installers across every category we sell.

Which Porsche models can use these LS swap kits and parts?

We support 911 (964 / 993), 996 / 997, 986 Boxster, and 987 Cayman & Boxster. See in-house platforms or each model page for how Porsche LS swap kits and parts apply.

Where do I buy CPE Porsche LS swap parts?

Buy U.S.A.-made Porsche LS swap parts in our online store: Engine Mounting & Transaxle Adaption, Wiring & Integration, Clutch Kits & Flywheels, and Ancillaries (Induction, Oiling, P/S, & A/C). For installation, planning, or a full Porsche LS conversion, contact CPE.

Do you say Porsche LS swap or Porsche LS conversion?

We use both terms. A Porsche LS swap and a Porsche LS conversion at CPE mean the same class of project—replacing the factory Porsche engine with a GM LS-based V8 using engineered mounts, cooling, wiring integration, and driveline hardware. See also our technical guides.

I am not sure which Porsche LS swap subsystem to order first—where do I start?

Confirm your chassis and manual transaxle plan first (see FAQ on automatics). Then stack Engine Mounting & Transaxle Adaption for your LS generation and gearbox, add Wiring & Integration with the correct reluctor strategy, then Clutch & Flywheel and Ancillaries. For a guided walkthrough of install philosophy on 996/997, read the DIY how-to and swap guides. Contact us for a line-item quote.

What transmission path do CPE Porsche LS conversion kits assume?

Our Porsche LS conversion kits and parts assume you are retaining the car’s original manual transaxle as part of the conversion strategy. Tiptronic and PDK are not supported for the LS swap as-is. See manual conversions and the FAQ for details.
