Pertronix 1741 Ignitor and 40,000 volt Flamethrower coil
Posted 28 June 2009 - 08:45 AM
I can get both these for $103 delivered.
I'd like to replace the Dist cap, plug wires, rotor if someone can reccomend a good set. I'd kind of like to have colored silicone wires.
Then it's new plugs!

Again I have to say when is it enough hp? A 150 hp KA is scary. 200hp is rocket ship. 300 would go back in time. Eventually you get to the point where you aren't enjoying the drive because you are too busy aiming it.

However since you have a L20 distributor you have to remove that ring above the point lube. That means you have to strip the dizzy apart.
have you done this bfore????????? As the kit is really for a Hitachi single point L16 distributor. Then its a drop in otherwise the L20b dizzy has to be modded. The Ring above the point lobe must be machine or the Magnet ring will not fit over the ring.

i have a the kit with the coil and i brought my diz to a local machine shop and did not have to rip it all apart. buddy just put the whole thing in a lathe and took off the nub!he charged me ten bux and i whent and hooked it up! the instructions that come with the kit say if you use the flamethrower you are to remove the resistor and i did a long time ago and she runs great! there is a plastic cap€ cover thingy that didnt fit in so i dont have it and ya its great get it!fuk points!
No, I have not done it. I have a single set of points though.

pertronix is for a single pouint L16 Hitachi distributor.
It will NOT fit a dual point dist. I say NOT!!!!!!!!
But can be made to work in the later single point Mitshibishi and single points Hitachi L20b dizzys.
In my DVD I mention one might be able to chuck it up in a lath and not take it apart if a machine shop can do it that way as mention by Polski
here is a L20 conversion removing the RING above the point lobe.PHOTos Below
PS I have had one L20b dizzy the holes would not line up on dizzy correctly. so it could not be converted.

Yours is a bolt in for the Pertronix!!!!!!!!!
I say installe the Pertronix first with your stock coil and ballast to make sure it works fine. Then if you just got to use the pertronix coil then install it. I hope you got the 3 ohm Pertronix coil as that is what is recommended.
If using that you will route the blk/blu wire also to the +side as with the blk/wht.
But for now just do it stock.

My dad was always changing the points on his 510's and got the accel optical setup later on, but as others have said, its not as reliable when dirty or in really dense fog for that matter.
If you use the ballast, it seems the spark is way too weak and won't run at idle.
I am using a 3 ohm 40,000v accel coil.
I don't think not using the ballast is fine, as the current doesn't go through the pertronix unit, but os more of triggering switch telling the coil when to fire.
I may be wrong, but I have had the ballast bypassed for years with no problems. I even gap the plugs to .040"

if using Pertronix 3 ohm coil you dont need the ballast but best to hook up the blk/blu wire(HOT START WIRE to the + of coil also with the blk/wht wire)

Here's a 1741 Pertronix on a Hitachi distro
Using a OEM Nissan 12 volt coil ($5 at the JY)
Wired directly to the coil and with the BlackWhite wire to power it.
It does say to use resistor if your coil needs it but.....
This is the same setup I use on 3 of my Datsuns
All I know is that it works and has not failed.

I'm glad someone dredged this up. I was thinking of putting in the matched pair,Pertronix 91741 Ignitor II + PerTronix 45001 Flame-Thrower II 45,000 Volt 0.6 ohm Coil
into the 510. I thought having the high power coil over the stock coil/balast setup might help smooth out the roughness I get between 6800 and 7100 rpm. Currently, I'm still running points, btw.
Any thoughts on other different or better options?
