When did they start putting coil packs in cars?
Coil packs began to be implemented in many vehicles during the late 1990’s. The biggest reason most manufacturers have turned to coil packs is they are more reliable. Many coil packs don’t require service for up to 120,000 to 150,000 miles.
Is the Optispark still using the optical module?
It still uses the optical module in the optispark, but no high voltage is passed through it. This will require some fabrication on mounting the stock LS1 coil brackets to the valve covers as well as getting the plug wires from the coils to the plugs.
Is there a LT1 to LS1 coil conversion computer?
LPE offers this LT1 to LS1 coil conversion computer to help eliminate some of the issues related to the optispark distributor. It still uses the optical module in the optispark, but no high voltage is passed through it.
Is it worth it to convert Optispark to coil pack?
Conversion. Optispark to coilpack? | LS1LT1 Forum Conversion. Optispark to coilpack? My cousin told me he heard of people with LT1’s converting the optispark ignition to a coil pack system. Anyone ever hear of this and how much does it cost? Is it a better route then replacing the opti? Is this worth it or just replace the opti?

When to replace the cap on an Optispark?
The original cap i replaced when the water pump went, then the 2nd cap went when the coil lead burned through the front of it, 3rd was the accel cap that was bad out of the box, now i think the accel optispark has gone bad after about 100 miles.
