Hello Folks !!...
I'm a new Member with a 95 Z28. With 85 Grand on the clock, I'll need to tune her up soon. I've never had "OptiSpark" before...but I was told I should change her to "Opti-Direct Ignition System". Has anyone here tried this system? It's supposed to be the same system as the "Caddy Norstar". Anybody have any info ??...
Thanks in advance

I have the delteq system and have no complaints. Its a waste spark design so it only has four coils as opposed to a coil for each cylinder but it has worked flawlessly on my car for about a year now. I've heard nothing good about the LTCC or delteq however they both have a few pros and cons. the LTCC requires some fabrication and doesnt come as a complete kit. However you can find everything you need with little problem. The Delteq comes as a complete kit, is very easy to install and works great, however it cannot be used with aftermarket ignitions so it could be a problem if you ever go forced induction/nirtrous. Also, be advised that both systems rely on the optical pick-up portion of the opti, it does not get rid of the opti as a whole, they just remove the spark from the cap/rotor of the opti which is generally the most problematic piece with the opti. As long as you're pick-up portion of the opti is functioning, both of the systems will work. Since I replaced my opti twice within a few months I decided to go the delteq route and have never looked back.

Thank you Dave89IROC I just emailed Baily to see how close he is to developing the bracket. Those coils are spendy when you have to buy 8... I'll have to price both out so I can compare.

Drive On...
