Hello and welcome to the ZR-1 Net Registry Forum. There is a wealth of information about ZR-1's available here.

We refer to our ZR-1's by the year and the last digits of the VIN. For example, I have 1993 #161.

The LT5 does NOT use the C4 LT1 Optispark system. The LT5 is a 100% electronic ignition system. The ignition system has proven to be very reliable and virtually maintenance free.

The Lingenfelter Package ZR-1's are excellent examples of what the LT5 can do. I own a Lingenfelter 368 and it is an amazing car. I highly recommend these cars.

As with any 20 year old car, there are issues that will come up. The major engine performance issue for the LT5 that I have seen is the need to replace injectors if they are original. Plugs and plug wires may need to be replaced at the same time.

I suggest that if you have a particular ZR-1 that you are interested in, post up here and get a member to go with you to look at the car, or look at it and give you a report.

Good luck,

Jim
