I can get a MSD ignition for pretty much free, but I am pretty skeptical that it will REALLY do anything. I talked to some guys that build racecars for a living and they were also pretty skeptical. I am running an internally stock n/a KADE with pretty much full bolt-ons. A while back I installed a MSD blaster2 coil, that I also got for free, and it seemed to make a small but noticeable difference. Maybe the ignition will help I guess, I'm just skeptical as hell about it. Has anyone ran one with any success?

bbejj123

well if ur getting it basically for free. You should try it out and let us know. I dont know if a lot of people would even think about spending that kinda money on an n/a KA ignition but id really like to know as well!

I just have to buy the right adapter to get the tach to work and probably another rev limit chip.

gives it better acceleration but it really doesnt really give the car anymore power.

smelly240

Do you really think you have any idea what you're talking about?

Anyways racepar1... on a NA car it wont show its colors. if u turbo the KA - maybe. The coil has already been upgraded - so i wouldnt expect too much from it

its free - so even if it doesnt work great - sell it to a vac adv v8 carb guy.




for the record "gives better acceleration = more power"


racepar1 knows more than you about everything, jdmstyle...

Is this question directed at everyone or only those with "an internally stock n/a KADE with pretty much full bolt-ons"?

racepar1

On a n/a engine with a modern ignition system, preferrably an import 4-cylinder. I know the MSD is a great upgrade on a dinosaur US v-8 engine with a dinosaur ignition system. I am basically looking to see if it makes a difference on a comparable motor to the one I have. A lot of people seem to use them, but a lot of people are morons. The fact that guys that build racecars don't think it would make any discernable difference really got me thinking. These guys have built and/or modified/maintained everything from vintage shelbys and camaros, to nascars and even campaigned a VERY successful trans am team (the purple ACS mustangs) and ran a speed GT corvette. I trust that they know what they are talking about. I'll probably try it and see how I like it, I am just looking for some input.

The Nissan ignition is pretty decent for what it is. I doubt you'll see noticable gains, but sometimes it will help eliminate some roughness.

Not worth the effort, even for free imo on a NA KA.

dunno,

On a KA-T some guys say if they use the MSD it will reduce the dadnation (sp?) on high RPM 400whp+ engines...

N/A...i don't know...Try KA-T.org for more info

On high-HP applications, it usually helps with spark blow-out. You reach a point where you can't run the gaps in the plugs any tighter and end up having to upgrade. Not sure if this info helps any but I say try it out and let us know. Goodluck!

Built in rev limiter dosnt hurt

i had MSD on my KA and the rev limiter wont change unless cause i had the 8k pill and i still redlined stock

I'm making 530whp on my stock S14 internal distributor (KA-T car not RB26). While I am an MSD dealer I would advise anyone considering spending money on such a replacement to stop because it is completely unnecessary. I've mentioned it a few times before on KA-T.org but just happened to notice this thread and hate to see people spend money where it isn't necessary.

I ended up getting one in a trade and ran it on my internally stock ka. You can definitely hear the exhaust note change and the throttle is a little "crisper" (for whatever thats worth), but what I did see is better fuel economy at the track (willow springs big & small track) When beating on the car at the track I was able to complete an additional run group before having to refuel. So, yet mostly unnecessary on street cars (though not bad) it is beneficial to those of us that see track days on occasion. Just my .02, its worth the install time.

I have an MSD SCI on my KADE N/A, and didn't really notice a difference at all except for I go through spark plugs like crazy. I replace them pretty much every oil change, or every other (depending on how hard I've been driving it). However, I did put down 145HP at 5000 ft. I don't have a dyno from before, but all I have are minor bolt-ons (intake, exhaust), I'm running E-85, and I'm using an S-AFC (the first one) to tune.

jspeedm

you should see a noticeable increase in fuel economy (2-3mpg street, up to 5mpg highway) and slightly quicker throttle response. but thats about it, no real performance gains.

Wow does anybody know what they're talking about here?

Its like 2/3rds the power of the stock coil.

On a honda it actually created a rich a/f vs a stock coil setup.

KA24DE, using resistor wires...only gain is the placebo.

jspeedm

Does anybody know what they're talking about here?

for na engines you don't need more power from the coil. you just need enough to jump the gap on the plug. you need more power when you run high comp or turbo engines because the air becomes more dense.

the msd (multiple spark discharge)ignition fires multiple sparks. they make the air fuel mixture burn more completely. by doing this, the short term fuel trim will not fluctuate as much. with more steady fuel trim comes better fuel economy.

Cleaner burn. The two or three sparks help with complete combustion. I'd say its more of an emissions thing or HIGH OUTPUT/COMPRESSION/FORCED INDUCTION engines ingnition system.

I always wondered about this. You see a lot of the Honda boys using these.

mxexux

IMO I've only heard of people that know what they are doing upgrade their ignition as a necessity and not to gain anything from it. The necessity would be brought on by high comp, forced induction, alternative fuel, or anything that the stock ignition system was not designed to tolerate.

Bigsyke

Like I said, the honda ignition outputs about 1/3rd more power than the MSD setup. There is apsolutely no advantage to using an external ignition system.

A 9 second civic is running stock ignition.

Those people dont know what they're doing.

I'd save the trouble and sell the ignition, keep everything stock. Less trouble down the road

slothonaleash

I've seen it done on an integra.... all it did was cause weird and random electrical issues... Though the kid who did the work did it for the under-hood eye candy.

We can't bring in Honda's into this argument, because:

1. Even though most Honda motors worth modifying with use an internal coil, the OEM Honda ignition system is VERY efficient for all intents and purposes, even with a turbo the OEM ignition system on the B series or later motor can handle the power. I've worked on a few Honda's that have had MSD 6A-Ls and the Blaster coils and they did jack shit, and in some cases made shit worse. Maybe upgrading to individual coils (even then use OEM Honda coils) but it's still barely an upgrade on a Honda motor.

2. Most of the Honda fanbois with MSD in their car don't know what they're doing, or installed it for the street cred for having another expensive part to show off in their engine bay.

Now as far as OEM Nissan vs. MSD igniton, I can't say much. But I do remember it supposedly helps clean out the powerband as it is a "Multiple Spark Discharge" ignition system.

I would like to see REAL data on this as I myself have thought about this on my Nissan, but that's mostly becasuse my SR20DE (yes, it's a NON turbo SR) uses an external coil and if/when it shits the bed I'd like to actually buy a new coil and not have to junkyard dive for a replacement. I fear that a new Nissan ignition coil might be hard to come by, and that's assuming my coil is the same as a KA24DE coil.
