I just ordered the stage 1 kit and was told that the stage 2 kit is still about 2 months away from beta testing and because I was buying stage 1 now was offered to be a beta tester for free. I picked up a complete coil pack with I.M. and bracket from a olds Aurora for $100.00 local to me could have gotten one cheaper if I was willing to buy one sight unseen from out of state. I will be mounting it back of firewall on a Porsche 944 with an LT1 engine.
Will be making my own plug wires due to long runs from the rear.

 

so i got 1 ?...... can i remove the rotor in the optispark? i have blown 6 of those into 1000's of fragments

 

You need to fabricate a plate to hold the optical disk on the shaft. Get a 1/8 inch thick round plate and drill the holes out to match the 2 bolt holes and the 2 dowel pins on the flange of the opti shaft.

 

I'm looking to purchase the LTCC setup and I was wondering where to purchase coils at?

 

Ebay item 7940889230 will work (D580, 12558948)

or www.gmpartsdirect.com

This may be a good alternative:

The MSD "Opti" is just a cap and rotor. I don't see that as a "breakthrough" replacement for the OptiSpark.

 

If the Cap and rotor are the parts that are always going out on the Optispark, and MSD has engineered a far supperior quality part, IE the optispark won't after 10,000 miles and you can run an aftermarket ignition system on it without burning it up, then a person wouldn't need a replacement at all now would he. I guess the question is how reliable is the MSD unit.

 

The optical sensor fails, the bearing wears out, rust from the bearing retainer plate blinds the optical components, the seals are not good, particularly in the harness connector tower. The MSD cap/rotor will not solve any of these problems.

The LTCC, Delteq and several aftermarket ECU setups remove the high voltage from the Opti, and typically discard the rotor - no help there from the MSD.

I ran an MSD box on the stock cap/rotor for 50K miles and never had a problem with the cap/rotor. It was the rust in the optical sensor that did mine in.

give it a try and let us know how it works.

 

MSDs new rotor is a new material, so hopefully that will keep them from flinging apart like so many of us have had issues with at high rpm/high power. Biggest thing is a better plastic (hopefully rynite like their caps, and also hopefully better screws holding it in place)

With that being said, the MSD cap/rotor isnt available yet. About 2 months ago MSD was quoted as being about a year away from being released when called.

 

What kind of warranty do they offer? I think that that is the real question. As long as they stand behind their work and back it up with a replacement when it fails within a reasonable amount of miles then that is fine by me. Keep trading them until you get a gem that lasts. There's always a few freaks that seem to work forever, like the 160,000 mile opti that was taken off my engine a few years back.

 

I'd be interested in a opti alternative but don't want to mount on the bottom front of car(rad.mounted) and also wish to keep my SS airbox. So mounting on drivers side valve cover is a no no. Does all the kits mount in these 2 locations?
Has anybody had any cons or disappointments from either of these opti alternatives? Seems like everybody is most pleased with whichever one they have chosen and have had no longevity problems or mechanical failures,is that true?

 

just hooked up the LTCC and the red light keeps blinking 4 times. I checked the wiring and everything seems right. IF any one had this problem and figured it out please write back.

 

Your white wire is not getting the right signal.

Does the car start?

I beg to differ. The MSD cap and rotor kit is available in the summit magazine right now. and its not too bad of a price, however that isnt going to change my mind about using an LTCC. I have installed too many of them not to get one myself. The difference in idle quality and how the car runs in general is reason enough for me to get one. Great unit! THANKS Bob Bailey!!!!
