4 cyl EFI, reluctor wheel needed

Post by Xplitive »

Non Jeep but closest equivalent would be an early 4 cylinder Jeep.
Looking to convert distributor from points to magnetic pickup for EFI timing control.
If anyone has done this, what did you use for a reluctor wheel?
Is there a difference between pickups? Right now the pickup used for converting v8 FSJ distributors fits, barely.
Last, I’m assuming rotor phasing is still a thing with 4 cylinder conversions.
Thank you.

For our FSJ's (and most other V8s), most of us have used the pertronix conversion kit: https://pertronixbrands.com/pages/pertr ... onversions

They make a lot of kits, they may have one for your setup?

Looking for what is, hopefully, no more than a $20 part since I have the pickup already from never converting my FSJ to EFI.
I had to come back and edit this. Pertronix does make Lucas stuff so now I need to go down a bunch of rabbit holes for efi compatibility… simplest would still be a 4cyl reluctor wheel. For the love of wheel.

I'd think you'd have your choice of maybe a dozen different reluctor wheels. Any of the V8 wheels would work if you cut off half the arms. It would probably even work with 8 triggers, and wasting every other one. No problem with the coil firing that often. You could also adapt a V8 distributor to the 4-cylinder block and run it with 4 or 8 triggers, as above. If this were the 134 distributor, it's a fairly small diameter housing, and adapting a different distributor might be a better way.

Did this ever get solved? Having made a bunch of electronic ignition conversions from parts I've some thoughts if there's still a need.
