In-House Conversions
Full-service LS engine swaps and manual transmission conversions. From consultation to completion, we deliver uncompromising quality.
Contact UsIn-house builds are primarily based on LS3 or LS7. CPE kits and parts support Gen 3 and Gen 4 LS engines, and our harness options require a 58x reluctor wheel (standard on Gen 4, required on earlier blocks when using our harness).
The Process
We discuss your goals, budget, and timeline. Every build starts with a detailed plan tailored to your Porsche.
Our in-house swaps are centered on GM LS3 and LS7 combinations, with package planning matched to your power and drivability goals.
Engine mounts, headers, cooling systems, and wiring — all custom-engineered for a seamless fit.
Professional installation followed by dyno tuning to ensure peak performance and reliability.
Comprehensive testing, road testing, and final inspection before delivery.
