Porsche LS Conversions & LS Swaps

One engineering team for in-house LS3/LS7 builds, DIY Porsche LS swap kits and U.S.-made parts, and technical guides—996, 997, 986, 987, and 911 (964/993).

At Chavis Performance & Engineering—often searched as Chavis Performance Engineering or CPE Porsche—a Porsche LS conversion and a Porsche LS swap describe the same idea: replacing the factory Porsche engine with a GM LS-based V8 using mounts, cooling, wiring, and driveline integration engineered for your chassis. We use both terms across the site so owners find us whether they search “conversion” or “swap.”

In-house programs are primarily built around LS3 or LS7 crate-style packages installed in our Baltimore-area shop. DIY and pro builders use our Porsche LS swap kits and parts—subsystem-by-subsystem components we design and manufacture in the United States—for Gen 3 and Gen 4 LS combinations.

If you use our harness and integration path, plan for a 58x reluctor wheel (standard on Gen 4; required conversion on some Gen 3 setups). Details on tools, timelines, transmissions, and pricing live in our Porsche LS conversion FAQ.

For install-level context on water-cooled 911, read the DIY how-to LS swap walkthrough and the growing Porsche LS swap & conversion guides (996, 997, cost, cooling, transmission topics).
