This page is the main landing hub for Porsche LS conversions at Chavis Performance & Engineering. Our in-house swaps are primarily LS3 or LS7, while our kits and parts are designed to support Gen 3 and Gen 4 LS engines.
If you are using our harness system, note that harness compatibility requires a 58x reluctor wheel (standard on Gen 4 engines; required conversion on earlier setups).
