Stage 4 - 500kw Plus

The Stage 4 Extreme kit's turbochargers are capable of over 500kw, however they are held back by the factory pistons and rods in the LS1 engine. Autotech have extensive engine rebuilding services that can meet your requirements if you are after more power. We build our own engines and they run as quietly as the factory engine, but handle applications well over 600HP.
