94 Optispark upgrade?

**ls1_02** · 05-13-2011, 06:15 PM

Can I make a 95-97 Optispark work correctly on a 94 camaro? I have heard the vented Opti last longer and would like to try it if its possible. maybe run a vacuum line possibly? I bought a new opti and it went bad after less than 1000 miles on it so when I replace it this time I want the best possible solution.

Even a non vented opti will last alot longer than 1000 miles. It was either a cheap opti (non gm), it was installed incorrectly, or there is another problem contributing to its' failure. And yes you can convert to a vented opti. I havent seen one in awhile, but at one point there were some online tutorials that showed you how to convert to a vented opti.

A vented opti I think just has the tube as 5.0 says.

What kind of opti did you purchase? I have one I took off my car that honestly I dont think was bad but I have no way to test it but I swapped it out when I changed a bunch of other stuff as well. As 5.0 said, unless it was a super cheap-o opti it should last much longer than 5k miles.

I bought a cheaper one so it's probably the issue...it wont even start now,when it did run it quit at any given moment. i was going to order an MSD opti, but I am open to which opti will be the most reliable. is the ac delco considered GM part?

YEP, ac delco is what GM used. buy that one and don't look back.
