Got the broken optispark blues? You are not alone. Here is the solution!

This is the LTCC (LT1-to-LS1 Coil Conversion) designed and manufactured to extend optispark life and provide much stronger ignition at high RPM/boost by allowing the use of the LS1 direct fire coils and eliminate the high voltage section of the Optispark. It also has a built-in adjustable rev limiter, a two-step rev limiter, and a built-in adjustable N2O & boost retard.

This unit still uses the factory optical module in the Optispark for reference, but no high voltage is passed through it. This removes the source of damaging ozone that eventually leads to Optispark failure.

PLEASE NOTE: Installation of this item is highly flexible as it will require some individual creativity on mounting the coils (making a bracket to hold the coils, etc.) and getting the plug wires from the coils to the plugs. However, the harness itself is plug and play, no splicing required. It uses 8 LS1 coil packs which you will have to purchase along with the following other parts:

8-#12558948 coil
Taylor Spiro-pro cut to fit wires or equivalent (NOT ultra-low resistance type).
Coil mounting provisions
