Lingenfelter Trigger Conversion Module For Late-Model Engine Swaps

Early hot rodders had it made, when swapping an engine was as simple as hooking up a few wires and a throttle connection. These days all the wires and computers can make things very complicated. Lingenfelter Performance Engineering’s trigger conversion module allows Gen IV engines like the LS3 and LS7 to be more easily swapped into cars like the 97-2002 Corvette or ’98-2002 Camaro without having to change the camshaft timing gear or crankshaft reluctor wheel. The plug-and-play design of the conversion module allows the otherwise-incompatible crank trigger signal from the late-model engine to properly interface with the earlier LS1-style harness.

Official Release


DECATUR, Ind. – Lingenfelter Performance Engineering (LPE) offers the TRG-002 58X to 24X Trigger Conversion Module that allows Gen IV General Motors V8 engines – such as the LS7 or LS3 – to be installed in earlier vehicles like the 1997-2005 Corvette or 1998-2002 Camaro or Firebird without having to disassemble the engine to change the camshaft timing gear or crankshaft reluctor wheel.

“Our new Trigger Conversion Module uses a plug-and-play design to connect directly to the engine’s existing wiring harness and factory engine sensors, allowing for a seamless and time-saving installation,” said Ken Lingenfelter, owner, Lingenfelter Performance Engineering.  “The conversion module has its own power and ground, and has been designed using the latest automotive-qualified components with extended temperature range operation.”

Lingenfelter’s Trigger Conversion Module uses a 16-bit microcontroller with an enhanced timer system to achieve precise signal timing for late-model GM engine applications.  The product features a fully encapsulated (potted) construction for increased durability and a high temperature glass-filled Nylon low-profile case.  Transient voltage and over-voltage protection have been incorporated into the design to accommodate the ever-increasing electrical demands of modern vehicle control systems.  It also incorporates a bi-color LED to indicate the operating status.

The Lingenfelter Performance Engineering TRG-002 58X to 24X Trigger Conversion Module (part number L460065397) is available direct from Lingenfelter Performance Engineering and retails for $254.95.

For more than 30 years, Lingenfelter Performance Engineering has created a matchless heritage of bringing astounding new capabilities to the world’s most sought-after sports cars.  This legendary record of precision engineering continues today, as the highly skilled Lingenfelter production team continues to target design excellence in engine packages, superchargers and high-performance aftermarket components that refine power, speed and control.
