Transform Your Porsche With CPE

Q: What is the difference between a Porsche LS swap and a Porsche LS conversion at CPE?

At Chavis Performance and Engineering, LS swap and LS conversion mean the same type of project: replacing the factory Porsche engine with a GM LS-based V8 using engineered mounts, cooling, wiring, and driveline integration. We use both phrases so owners find us regardless of search terms.

Q: Should I choose DIY Porsche LS swap parts or an in-house build?

DIY is aimed at experienced builders comfortable with major mechanical work, fabrication, and wiring. In-house turnkey builds are for owners who want CPE to execute the full conversion in the shop with staged payments. Same engineering team supports both paths.

Q: Which Porsche models does CPE support for LS swaps?

CPE develops systems for 911 964 and 993, 996 and 997, 986 Boxster, and 987 Cayman and Boxster. Support level varies by chassis; 996 and 997 are a core focus with broad in-house and parts support.

Q: Where are CPE Porsche LS conversion parts made?

CPE branded conversion parts sold in the Engine Mounting, Wiring, Clutch and Flywheel, and Ancillaries store categories are made in the United States.

Q: How do I get a quote for a Porsche LS engine swap or conversion?

Email or call CPE with your chassis, goals, and timeline. We will walk through in-house versus DIY parts scope and next steps.

Education

What Is a Porsche LS Conversion?

A Porsche LS conversion replaces the factory engine with a GM LS-series V8. At CPE, we engineer every Porsche LS swap so the LS package fits your Porsche’s chassis, cooling, and driveline while improving power, reliability, and serviceability. For subsystem shopping and how kits are structured, see Porsche LS swap kits & parts.

Many owners choose an LS swap after dealing with known weaknesses or high rebuild costs on certain original Porsche engines, or simply because they want modern torque, sound, and tuning potential without giving up the Porsche chassis they love.

At CPE, we design and build conversion systems so your car performs on the street and track—whether we install it in our Baltimore-area shop or you assemble it from our DIY components. In-house programs are primarily LS3 or LS7; our kits support Gen 3 and Gen 4 LS engines, and our harness options require a 58x reluctor wheel.

Benefits

Why Convert to an LS?

Significantly increased horsepower

LS platforms deliver far more output than many factory Porsche engines, with room to grow through cam, intake, exhaust, and tuning.
Improved reliability

Owners often move to LS power after repeated issues with certain original engines—LS combinations are proven in street and track use.
Easier maintenance

Parts availability, familiar service procedures, and widespread technician knowledge make long-term ownership more straightforward.
Strong aftermarket support

From exhaust to ECU tuning, the LS ecosystem offers more options than most legacy Porsche powerplants.
Overall performance

Better torque, modern drivability, and tunability add up to a driving experience many owners prefer for daily and track use.

Common questions

Porsche LS swap & conversion

At Chavis Performance & Engineering, an LS swap and an LS conversion describe the same work: replacing the factory Porsche engine with a GM LS-based V8 using engineered mounts, cooling, wiring, and driveline integration. We use both terms so owners find us whether they search “swap” or “conversion.”

Should I choose DIY Porsche LS swap parts or an in-house build?

DIY fits experienced home or pro shops assembling Porsche LS swap kits and parts themselves. In-house fits owners who want a full conversion performed at CPE. See the FAQ for fit, tools, and timelines.

Which Porsche models does CPE support for LS swaps?

We support 911 (964 / 993), 996 / 997, 986 Boxster, and 987 Cayman & Boxster. Scope differs by chassis—see in-house platforms and the FAQ.
