Sirpent Posted March 18, 2011 Posted March 18, 2011 Hi again, The cleanout continues. This distributor was a spare I had for the L20ET Turbo I had in my car, now I'm no expert however I would say this could be used on other applications also. If any experts on the forum could assist or verify it's applications please feel free to post in the thread. There is NO play in the assy and all looks to be in order. The disi has a clearly visible Nissan logo embossed on the housing with the Nissan part number reference : 22100 - P8010 Cheers John Quote
Moderators Zedman240® Posted March 18, 2011 Moderators Posted March 18, 2011 What type drive does it have John? Is it a spline/tongue or just like a standard tongue? Quote
Ben Posted March 20, 2011 Posted March 20, 2011 I'm not sure that's a turbo dizzy - it's a reluctor setup with no home trigger?? The 280ZXT/HR30 is optical, and is internally interchangeable with the Z31 VG30 PCB and trigger disc. Quote
Sirpent Posted March 20, 2011 Author Posted March 20, 2011 Hi Ben All I can say is that this dizzy came off the 1st L20ET motor I installed in my "Zed" on the way hack from Morwell at about 11.00pm on a Sunday night, I down shifted and suddenly heard a ruckus from the engine bay, I looked in the rear view mirror and saw a trail of sparks and smoke, when I pulled over and opened the hood I found that #1 Rod was hanging out of the block assy, obviously the rod bolts had given up and sheered. I then purchased a 2nd L20ET from EKW Nissan, that one did have an optical dizzy as you stated, and that's the one that ended up going with Mick to Adelaide, but this one was the spare from the first motor. Cheers John Quote
Ben Posted March 20, 2011 Posted March 20, 2011 Yer, I looked up the part number and it shows up as an '83 L20AET. It looks like there were at least 3 different ignition systems in the 'L6T' motors - optical, reluctor and hall effect (trigger on the harmonic balancer). The optical one is the only one with a home trigger (and therefore suitable for direct-fire or fully sequential injection). I'll let you get back to selling it now! Quote
Sirpent Posted March 20, 2011 Author Posted March 20, 2011 LOL Cheers Ben you had me worried, I thought Alzheimer's was setting in after all its been sitting around for 18 years now ! But since you have info on it, what is the suitability of it for other app's so that potential buyers can gauge if its a worthwhile proposition ?, honest opinion of course. Cheers John Quote
Ben Posted March 20, 2011 Posted March 20, 2011 I didn't do too much digging - just a google of the PN... I'm sure it can be retro-fitted with fancier internals (if required). But it would be perfect for a project requiring full ignition control, but not sequential/direct-fire - I had to lock up my dizzy in order to make the advance curve programmable. Quote
Moderators Zedman240® Posted March 20, 2011 Moderators Posted March 20, 2011 Tricky part is you may have to find the oil pump drive spindle for that distributor; the standard one won't fit. In the US they are common. Quote
Sirpent Posted March 20, 2011 Author Posted March 20, 2011 Hi Dimmitri, Thanks for the info, the spindle on this dizzy is removable, there is a securing pin that locks it to the main shaft. Cheers John Quote
Moderators Zedman240® Posted March 20, 2011 Moderators Posted March 20, 2011 Oops..yes you are right! forgot about that little detail. I'll shut up now. Quote
Sirpent Posted March 20, 2011 Author Posted March 20, 2011 LMAO.............. No problems buddy, I just thought that maybe there were different variants and wanted to point it out. So your prognosis now as far as useability? Cheers John Quote
Moderators Zedman240® Posted March 20, 2011 Moderators Posted March 20, 2011 I did buy one of these off an NDSOC member a while ago when I was specifically after an optical version of this distributor. I'm sure it can be used in place of an 280ZX elec unit with just some re-wiring done. If you can figure out the wiring, you can hook up the coil to it and run the engine without the ECU it normally hooked into. Quote

If you can figure out the wiring, you can hook up the coil to it and run the engine without the ECU it normally hooked into. Careful there - this dizzy doesn't have any vacuum or mechanical advance assemblies in it. If you retrofitted it to a 'normal' L28E, you'd have only static timing... Quote
Moderators Zedman240® Posted March 20, 2011 Moderators Posted March 20, 2011 Sorry, I'm still thinking with my EFi head on that! That's what I was thinking of doing with the one I had but with this model you cannot run a distributorless setup as there is no reference for cylinder #1 available. You could run this distributor with an aftermarket ECU to get the timing right. Quote
