Default What MSD do you have???

I'm looking to get a new ignition setup. I have an upgraded coil, but I'm thinking of upping the nitrous and I was told I need a stronger ignition to do that. There is a possibility of a blower in the future.

I was wondering what you guys/gals used and how much it helped or how you liked them. Please Chime in with any comments, the more info the better. Thanks :cheers:

[EDIT] I also saw something about an installation harness for the MSD's. Is it worth the $50. Does it make install that much easier?

I run the Digital 6 with harness not included . This unit retails for $289 . I have the entire setup plus all the safety featurs on a Wet NX sys for sale for $675

Yes the quick harness is worth it, You can install in 5 minute minus the mounting time.

$1400 invested!!

MSD-6AL :thumbs:

It'll do the trick, and the built in rev limiter should be a given for your nitrous setup.

I ran a 6AL until it finally gave up on me a couple months ago. Just replaced it with a 6A since I never used the rev limiter in it anyway and my stock one is set so high it should never hit it either.

Scorp,

Why the 6+??? Are there any features or performance gain(not likely) to justify the extra $$$ of the 6+ over the 6AL.

Did you guys use the easy install harness with the Digital 6+? A few degrees less on the timing with the nitrous could save my pistons on my new engine, that's worth the extra $80.

Yes. The timing retard is easy, just hook a 12v line in series with your nitrous solenoid. Solenoid goes active, timing retard goes active.

So was I in the "yes" part of my reply. :) I have the harness for the L98 engine and it made the install very easy.

MSD Digital 6+ with adapter harness here. I have the rev limit set before the fuel cut in the PCM, lower 2nd stage rev limiter activates when the line-lock is on, and timing is pulled when the N2O hits. FWIW, if I wasn't also spraying I'd run the stock 1996 ignition with MSD wires and NGK plugs. Any older LT1 you'd want to upgrade the coil also.
