Just wondering which digital ignition is the best. I kind of like the MSD Digi 6 with the retard features, so adding nitrous is easy. I'm not sure about how output compares on these. I may have an opportunity to get the Accel setup pretty cheap. Let me know experiences and opinions. Thanks.

Well, I dont have either, but I have been looking into this same topic... at first I was gonna get the 300+ system. But then, after haring all of the great things about the MDS 6AL, and with all its features (timing retard, rev limiter, etc.), Im going with the MSD. Even if the MSD ends up costing a little more, Ill know that I have the best available!

All of them do the same thing, give you a better spark and mutiple sparks, if you were to dyno them to see a difference, you proably wouldent. I have the Accel 300+, I like it cause its half the size of a MSD and it comes as a kit, Coil, plug in wireing harness, (for your car) and box. It has a rev limiter adjusted with switches. Ive had mine since 95 and not a single problem yet!!

Really? I didnt know the 300+ had a rev limiter. Hmm... now ya got me thinkin twice! I gotta admit, Im not too big a fan of the "big red box". Ya know what Im talkin bout!

Yep, it can also be adjusted for 4,6 or 8 cylinder engines as well. The rev limter starts at 4000 or 4500 (cant remember which) up to 12,000 in 250 rpm incerments.

Well, looks like im sold on the 300+! Thanks for the info man.

jacobs pro street is better than all 3 of those.

Jacob's is getting my dollar too. The Pro Street is quite a system!
It comes with a rev limiter (dial operated I believe), anti-theft system, coil, box, and custom harness too.
Also, what i like best is what the box does. It has an "acceleration mode" which increases spark under throttle, and backs it off once you level off for better milage. Also, the Jacob's brain monitors the condition of each cylinder and adjusts spark on a cylinder to cylinder basis for the best combustion/performance.
Plus, you don't have to remove any of your stock stuff, it gets signal from the stock coil. This is good so "just in case" it fails, you still have your stock ignition.
That's alot of good stuff.
I've heard good things about the Crane systems too.

My vote goes to Jacob's as well. MSD 6AL isn't a digital system, the MSD Digital 6 is, however.

We can get a digital system on our HEI systems?? I thought we can't use those cuz we don't have DIS??

Im not trying to sell anybody the Accel 300+ system, but how much does that Jacob's system cost?? I know the 300+ system cost me 181 bucks and it is digital.

The jacobs system will run you about $380 if you shop around. Couple of things to remember about that. One is that it includes a coil, second is that it puts out ALOT more power. all the other boxes put out about 500 milijoules, the Jacobs box uses the sparkplug as a sensor and varies output up to 1500 milijoules. After it hits the coil the jacobs unit puts out enough power knock you out, I know cause I was stupid and it put me out cold in my driveway. The Jacobs warranty is cool to, after the initial period its send it in, they fix it and send it back, $24.95. But it doesn't have a lot of the cool features that the new boxes in the same price range have. Most boxes in this range have rpm switches and such. But I love mine. Forget the MSD 6al, it's yesterdays technology, and really is not that great compared to the stuff you can get for the same price today. Here's one thing to bear in mind though. A few months back 4 wheel magazine did a comparison test of 4 boxes and saw no real change over just keeping the stock ignition components in good shape. 3 of the four lost power, one gained, but all the differences were less than 2hp, so just log that off to testing variances. Though those were peak numbers. They do offer improved low rev and start up performance with the multiple spark. Also remember that to get the full effect you need to adjust the gap of you plugs, usually larger. If your engine is stock or close to it, spend your money on something else like exhaust or intake. Once you get the engine hopped up a bit then think about a ignition box.

Jacob's Pro Steet system is $355.95 from Summit.

So what are some of these systems that are "current" or "ahead" of the Jacobs Pro Street system? ... you didn't mention anything.. also, what (for the same price range) is the best bet compared to the Accel/MSD systems.. you also mentioned systems that replace these for the same price, and are better...

I have a mallory Hyfire VI CD ingintino box. SO far is being great.. definetly an performace increase after I disable the CMS on the car... Allot of folfs cheer for MSD... is about choice.. MSD has built a reputation for it self.. but so have the others.... My best advice is call the manufactures and ask for literatures.. then you will know what company you are dealing with...

MSD ALL THE WAY. I had the accell 300+ and I hated it, it kept getting interference from the plug wires and misfiring. Took it back and bought an msd, LOVE IT. PLUS msd has all kinds of cool **** like Adjustable Timing Control, RPM Switches, Anything you can think of. The accessories are worth it for the MSD
