Subject: Need advice, Gurus - GM Opti, MSD or Dynaspark? by VtVette on 2010/5/9 23:09:47 Fellow Guru's, my '93 has 98k on her and I have use of a friend for a few weeks so, I decided to do a little preventative maintenance. I don't think my car has ever had a tune up so, I replaced the filters, fluids, plugs, wires, and decided while I have it in the air and apart i'd change the opti. I was originally going to go with a Delteq unit (I bought one actually) but, I really want to keep my car stock looking under the hood so dizzy-less ignition systems are out. I removed original Opti today and cleaned up the front of the engine. Much to my surprise the Opti looks to be in great shape - no sign of any water or moisture ever getting in. Bearings seem tight. Must have got a good one! So, I have a few options: Stock Opti - I would do this in a heartbeat but, mine is non-vented. That's my only concern with a factory original piece. MSD - these seem to get mixed reviews. Worth the money? I *heard* MSD admitted that there were issues with early units but this was apparently cleared up by '08ish? Dynaspark - now we're getting up in price. Are they really worth the money? I like the idea of a vented Opti. I am not going to swap my cam at this point so, no update to a later unit for now. I'd love to hear some opinions. Thanks, Brian |
