msd opti distributor?... i was thinking about getting this with my next pay check, but it's a pricey unit ($515 from summit). my thinking was that i was gonna complete the exhaust next and while i was gonna have to replace my plugs and wires i was just going to replace the opti while i was ahead. plus this unit allow me to easily adjust timing and i want to spray. i know it's not entirely necessary but are there any thoughts on this? would i be throwing away money or is it a good investment? thanks.
If your going to spray the car I wouldn't use the msd opti to adjust the timing. I would get an idnition box with adjustable retard control or buy tunercats. You will have to make some timing marks if you are going to play with the msd opti's timing screw. And you will be leaving n/a power on the table by retarding timing there. If you run a mallory 685 box you can pull timing while spraying.
But I do like the msd unit. Good luck

Save your money or spend it on other parts. If you want to replace your opti,just buy a new one from GM. If installed correctly and kept away from moisture (under carriage washing) it should last a long time. As far as rpm, I spin mine to 6500 shift points with no problem.

I picked up 14 hp by switching to the MSD...even with a 12 bolt that was also new. I made 934 with the stock unit- and stock 10 bolt w/4/10's. Then made 408 with the MSD Pro-billet with a Strange 12 bolt and 3.90 gears. Curve was much smoother.
I was a hard core believer in the MSD...but at the track a couple of months ago- the car puked the MSD too. i think it is something in my engine causing this- I have been through 5 optis(all factory GM's from the dealer, until the MSD) in 30,000 miles with the 383 setup. The MSD did last longer than the others(~7,000 miles), and they were way harder miles.
EDIT- just saw your signature...yeah I would definately spend the money elsewhere. IMO- the stock peice is fine for your power output/stock compression. I would put the cash towards a nice stall convertor if I was you.

Its not necessary til your Stocker is going out. However, i LOVE the MSD unit. Beware there is two different part numbers depending on your year model. If you have the money, then i say why not, it will be the first and foremost mod on my next LTx car.

My MSD Opti is performing really well in my car and is more durable then the GM at high RPM. Also, I slightly tweaked the timing adjustment screw on my MSD Opti (more advance) and my car picked-up a full tenth! Initially, I had some issues with the MSD rotor screws getting loose. However, I used some Allen socket-head machine screws with flat washers and thread-locker for the rotor and haven’t had any more problems.

Be aware that most people are too STUPID to understand gains they see with a whole new ignition system are because they were replacing worn out parts.
In a case like The Engineer's above it means his tune was wrong if he gained by playing with the screw.

Yeah, I think there's a lot of hit and miss scenarios going on with the MSD optis...I replaced my stocker with another stocker a few years ago and its been fine...I went with a true AC Delco GM original, though...I spin mine to 6500 all the time...
