Hello everyone.
A friend of mine gave me a used external MSD coil (blaster2).
i bought a cap and rotor MSD PN 82923

But the car dont work good. at 5500 rpm when i have 22psi of boost
the ignition is unstable , instability and the car cant go under 6000 rpm
problem with the coil?? (i didnt use the ballast resistor)

I changed to OEM distributor and works well but at high rpm a heard
a bit confusing sound.. i try 2 diferent distributors.

My car needs ignition upgrade??

IF YES what do you advice me? buy another MSD external coil?? (which one?)
or the internal ACCEL??

Nick_p

anyone???

accel ACC-11076 internal coil

or

MSD external coil SS

Really the stock Honda ignition system is supposed to be good for up to 600whp. I have 520whp on a stock ignition system (minus the spark plug wires) and it has been running just fine for me. I would check your basics. Do a new cap, rotor, plugs, plug wires. Make sure your base timing is correct as the wrong timing can cause you all sorts of problems. At 450whp I wouldn't really mess around with aftermarket ignition components as this just ends up complicating things. Good luck.

i use a stock ignition system 450-500hp no problems. i change out the cap and rotor every year and spark plugs a few times a year. the trick is the right spark plug and gap. im using the ngk 4554 8 heat range plug with the gap at .018.

I'm on stock ign, 577hp @ 30psi no problems. I use ngk bkr7e plugs. A lot of guys use stock ign and are well into 800hp.

Yea oem ingnition here too...Started with MSD and it gave me issues. Went back to oem with a .20-.24 gap and have no issues since. IF youre going to get something other then OEM. Go with M&w pro 10 kit from T1. if you cant afford it stick with oem

MSD =junk imho i had all kinds of issues with mine when i first started this, and my **** was built by a shop. the timing would fluctuate alot with it.

i opted to switch to something that would benefit me down the road, and havent had an issue yet 3 years and counting

i went pro14 with cam trigger myself, and cop

As stated MSD on honda's just don't seem to work. I had stock ignition over 500whp. What ems are you using? Why I ask is if your running say AEM it reads the cam signal a bit different than the oem ecu's do. So if you distrubitor isn't in perfect condition it may be causing issues. At first I couldn't get my car to idle below 1500rpm. Changed out the dizzy for a new one and the issue went away.
First ditch the MSD crap and try just a stock dizzy with new cap and rotor.

I already changed :

-spark plugs with NGK iridium BKR8EIX with 0.029" gap
-plug wire with NGK wires. i make a measure and
found 3.3 kohm at 4th cylinder, 4.3 at 3rd , 5,35 at 2nd and 6.3 at 1st

-New cap and rotor with geniune Honda. (i changed them before 5000 km.)
-i didnt change coil never and other components

i used P30 OEM ecu tuned with Crome .

shouldnt be any reason why you would need to upgrade your ignition at the power level youre at. Local guy here tunes a 700hp B series stock ignition on corn.

Stock ignition "works" for up to 600 but a higher energy ignition gives better spark and a more complete burn and therefore makes more power. Simple setups can work but that lasted 2 coil is junk. If your to going to use a box with col then just run stock stuff. Without an ignition box the stock ignition doesn't work well with just a big aftermarket coil

i tried msd and my car ran like crap with it and one day at high rpm the rotor shattered inside the cap i have no idea why but it made a mess. i started reading about them on hondas and the isues seem to be endless. the only upgrade im gonna do is the cop conversion. the gap your running is a bit big too i would close that gap a bit.

I dont know if its in your budget. But i just got the AEM EMS series 2 and the AEM Coil on Plug conversion... its expensive, but an option. That way you can do away with distributor problems all together.

Nick_p

ok... thanks everyone for your answers.

i have no money to spend on this so i try to find the solution for good working condition of electrical power at my levels.

so...you advice me to avoid the MSD solutions.. ok!

for sure i need to buy a coil..this one (oem honda) has 15 years on his back.

the accel internal coil is worst than the OEM honda?
do you have any other simple solutions?

finally what gap my setup needs to ran better?
i use oem ignition
spark plugs with NGK iridium BKR8EIX
CP 9.0:1 cr 81,5mm

need i a diferent heat range spark plug? In my city the temperature at winter is about 0-5 celsius and at summer about 40 celsius

blackeg

8 heat range is fine, though you can probably use a regular plug instead of the iridium.

your gap is too large, bring it down to around .020 inch

sanman000719

agreed .020-.025 should work well

I run the ngk4554 gapped at .22 oem dizzy, ngk plug wires on hondata s300 and made 665hp with no issues at all just my .02

sanman000719

his dizzy was crap i had 3 of them before i went to the pro14, and t1 trigger. if i would have sooner i could have save a little money lol

Nick_p

so...your advice is to fix the gap at .020-.023 first and then go for a coil if the problem exists?
geniune internal coil?

the spark plugs are iridium and i have a lot of them for now..


lol...what part exactly is "dizzy" ??? sorry....i am not from America.

sanman000719

no the internal coil is crap and rpms is what kills it

you need an external coil ran to the stock dizzy i have never had thos setup myself but see alot of people using the crane ps92 coil if im not mistaken

Whiterice-gsr

dizzy = distributor, its just slang.

Running a summit digital cdi ignitionbox only 135 and crane ps92n coil 69 dollars and it works great. I was recommended the ignition box by Theshodan and it works flawlessly. Currently running a .0032 gap at 406 whp 17 pounds of boost. With stock coil and with after market coil without the box my gaps had to go down to .0021 and with the ignition box it picked up low end torque and a few Hp up top

Nick_p

Ok lets focus on the "ignition box with crane PS92 coil" solution.
which ignition box? any advice?

this method works with p30 ecu tuned with crome?
need something more?
how to connect them into my car?

Well one of the things that fails on our cars is the igniter because it's inside the dizzy and it gets hot then fails. There are two ways around this. Remove the igniter from the distributor and retire it to a cooler location, or remove it all together and build a igniter bypass circuit or have someone make you one if your not familiar with soldering circuits.

Then the box will connect to the output of the circuit or the igniter and that I'd then wired to the coil and then you run a distributor cap that accepts and external coil wire. I am running the mad pro cap and rotor. They work great. Their cheaper caps I've had issues with
