In another post on this community, partially just trying to generate a conversation, i asked about adaptable coil-on-plug modules. A couple folks were helpful, but it’s still thin on the ground here, that’s cool, it’s all new, etc. Here it is: https://lemmy.world/post/1263808 (not much).
But I’m serious about designing and building a new ignition system for this ancient, forgotten engine that I’m kinda expert on by now (that expertise plus five bucks buys me coffee at starbucks). I’ve got two cars with this engine now, it’s just barely tenable to drive now, parts are extremely scarce (eg. timing chain setups).
Anyway this engine, the Rambler 195.6 cubic inch inline 6, has roots back to the 1940’s, AMC slapped a shitty OHV head on the old flathead engine, introduced a number of reliability problems, then solved those just as they introduced the brand new design engine, the 199/232/258.
It’s got a once-conventional distributor, contact points and coil ignition. There’s a Pertronix in there now. It works fine, but I hate them – the distributor has to crank two rotations before it fires the coil, so the engine cranks for over a second each time, instead of firing right up on the first contact-point opening. I WANT THAT BACK.
So I’m gonna make new electronic guts for the distrib, drive some form of coil-on-plug, and do software spark control in the computer I’ve got already running the electronic carburetor.
ITT is chat about research, photos, etc. I’ll make a web page for the project like I usually do. My Rambler Lore website is https://www.ramblerlore.com/index.html
Here’s the page on this engine: https://www.ramblerlore.com/AMC/195.6ohv/index.html
YES! Thanks!! Wow, the devil’s in the details… They “all look like that” but on the few I’ve seen, the long snout is cast plastic and not removable. That makes a huge difference. Thanks so much for the detail!
Gonna get to an LKQ (junkyard) next week and try to find one for a look-see. Nothing like having a thing in your grubby hands for gathering information.
Seriously, I can’t thank you enough. This is great info.
You’ll probably be hard pressed to find a B15 Sentra with a QR25 in it. It was only available in the SER and Spec V. BUT the 4 cylinder Altima (iirc 2001-2006) SHOULD have the same coil pack (same engine, different tune)
Failing that, look at LS1 coils.
And no problem. I literally do what you’re doing for a living. Mostly.
Ok cool explains the diffs re: rockAuto. Or they have afu listings, hardly the first time… I’ll hunt those down.
What do you do for work? If I did this, I probably wouldn’t do it for fun! Lol.
I like doing work from first principles. Luckily since I basically have no choice. Electronics and software was my loving, once. .
I own a “race car shop”. We do everything from maintenance on people toy cars, to full frame up builds, resto mods, machine work/engine building, custom complete (“Mil-Spec” god I hate that term) wiring harnesses, to race car development/builds.
Basically we take shit that was never meant to go together and put it together to make people go fast.
