Question about MSD for my KA-T

Post by **Jookmasta** » Fri Mar 12, 2004 9:32 am

ok so i have the main components for my turbo kit and im now sourcing the electrical stuff so that when summer comes around, i can put it all on. i was wondering which MSD ignition is the one that most people use. im gonna be running just 8 psi. so what model do yall 8psi people buy?

Post by **Structure240sx** » Fri Mar 12, 2004 9:32 am

you dont really NEED to upgrade your ignition for a while. but if you are going to like i will be soon a 6al will do good. im going to be getting it with the btm also

MSD 6BTM...its the ideal one, it will retard the timing depending on how much boost your running...i think they're on ebay for $200 or so, not sure...

i wont use MSD because its mostly for domestics and it is very very hard to hook up

my plans are to run HKS; Twin Power. you can read about it here:http://www.hksusa.com/products/more.asp?id=838

so 6al or 6btm?

That's quite an ignorant thing to say, there are many universal units- such as the 6BTM that can be hooked up to just about anything 4, 6 or 8 cyl. And if the installation instructions aren't easy enough for you, you can call their tech help line which is first class- tell them your car and what your installing and they'll read you the colors and locations and how they hook up. Sorry for the rant.....but i happen to think they make a good prouduct.

I can't comment on it being difficult to hook up, but why would you think that HKS's unit would be more suited to the KA...just cause its a japanese company doesn't mean crap in this case, they wouldn't know a KA from a sbc...its not used in anything over there, it could almost be considered a domestic engine...almost...

point taken, but which one? 6al or 6btm?

Post by **WDRacing** » Fri Mar 12, 2004 9:32 am

6 BTM...you'll need the proportional boost/timing retard.

MSD install is very simple. I hook up 6btm and blaster2. Basically just hook up wires, and splice 2 wires from coil. One of the simplest mod. Do not require a tach adaptor for my s13, not sure about s14.

Good and cheap option to run boost retard without affecting ur stock timing. More spark is a plus.

Actually, to hook up the MSD BTM to a 240 is a tad more involved. You need to drill a hole into the cap, cut a circuit tand and solder a wire in place. Since the coil is internal...

There is a very good write up of this in the tech support page of JWT.

This is only in S14s case.

Id also look into Crane Cams ignition kits, they come with the main unit (with knob adjustable RPM limiter) and high power coil for roughly 250. Its not bad, then you just need to buy the boost/retard unit seperately, not sure how much, but it can't be too bad.

MSDs BTM does advertise that it also increase spark output by itself...

i guess then the next best question is if anyone knows the cheapest place to find a msd 6btm. (i already checked ebay, but this seems like one of those things that i would prefer to buy new.)

Post by **SHIEF** » Fri Mar 12, 2004 9:32 am

I have (and will be running), the MSD Digital SCI. It will control lauches and retard timing on nitrous when you hit the button. I'll have to buy the boost retard seperate, but oh well.

Yup that's it WD. At what amount of boost would you start to use that? Around 15+?

Post by **NX95240** » Fri Mar 12, 2004 9:32 am

i have the msd- SCI and it was hell to hook up because of msd tech sent me the wrong wiring spec. took half a night to get the thing hook up.

Post by **Jookmasta** » Fri Mar 12, 2004 9:32 am

it seems that there are two kinds of msd btms. the one that WD gave the link for is different than this one

http://store.summitracing.com/...D6462

There is a major price difference but it seems that WD showed one that just retards the timing when boosting while the link i put above is one that is an ignition system and does the retard the timing thing. correct me if im wrong?

You'll want to start retarding ignition at 5 psi or less. Most programs and rom tunes will take out .5 degree's per lb of boost.

Post by **Jookmasta** » Fri Mar 12, 2004 9:32 am

so the link u gave WD is the same product as the link i gave?

Post by **WDRacing** » Fri Mar 12, 2004 9:32 am

The link I gave only modify's your ignition advance, the link you posted does the advance while giving you a bump in current. If you can afford to, I would use the MSD you referenced. If not, then the other will do fine. I know you don't plan on more then 8psi right now, but that will change. So the better MSD would be a nice investment.

im getting ready to order the msd 6btm since my car is finally running very well. my question is that it says you can retard ffrom 0-3 degrees. theres a spot for 0,1,2,3. if you put the knob in the middle of 0 and 1 will that be .5 degrees? im not sure if they have a little click kind of thing for it to only work on whole numbers or what.

Post by **WDRacing** » Fri Mar 12, 2004 9:32 am

Yep, anywhere from 0-3 degree's.

Post by **Structure240sx** » Fri Mar 12, 2004 9:32 am

nice, ill order it today probably

Post by **HIGHLIFE1** » Fri Mar 12, 2004 9:32 am

i'm using a msd digital 6 + seems to be workin great for me.

cool thanks for the help WD. i guess ill have to bite the 300 dollar bullet but like u said, it'll help in the long run

Post by **FDAPolice** » Fri Mar 12, 2004 9:32 am

Since my cam shaft sensor is bad on my 98 KA24de, could I just buy a MSD ignition system instead of buying the new sensor from nissan? I really don't know much about the electrical part of the engine. What would I have to buy??? I was looking at the MSD Entry Level Ignition system, what elese would I need? Thanks
