RX distributors

yeah rebuild the diaphram inside the thing - the photo's helped him work out the right spot to place the arm thing

and yeah, can take pic tomorrow

pic attached.

why he painted it blue is beyond me, but still better than the nasty old metal look

I'm impressed at the clean look of this thing. I have opened one up as carefully as I could and it was a mess. Painted generally means reco in some peoples eyes. The worst reco paint job I have seen is the old Electrolux 720 vac cleaners once were orange plastic, painted blue !

Bringing this old thread back because I need a rebuilt diaphragm actuator assembly .
I gather I just send them the actuator now that they know where its "neutral" position is ?

Thanks all , Adrian .

spot on. just send it to them

I pulled the actuator off my spare EA82T dizzy this afternoon so I can send it away tomorrow .
I need to know if the Auto's distributor or actuator is any different because I think the Vortex it came from was a front wheel drive one .

Steptoe does your early factory WSM show any differences between manual and auto turbo dizzy's ?

Cheers Adrian .

BTW we changed slightly the clock springs tension in the AFM today and it does feel a little better , still a little retarded timing wise but a working dizz actuator will help a bit there .

No mention in the manual nor was I asked by Subaru when I got a new one. At the time mine was auto, is now manual and have only gone from good to great with the conversion, so don't worry

Thanks Steptoe , I mailed my spare dizzys diaphragm assembly off to that mob in QLD this afternoon so hopefully have it back soon .
My car is doing a few weird things and fingers crossed having the distributor working properly will help .
The timing feels retarded but I'd like to have the actuator working properly before advancing it up .
I noticed the part of the dizzy that the actuator pulls backwards or forwards was quite stiff , a bit of working it back and forth did free it up and reminded me that mechanical distributors need to be pulled apart occasionally to clean and lubricate the advance mechanism . They get dust and crud in them and parts that should move freely get a bit stiff which could affect the rate the bugger advances/retards .

Also to be 100% sure can you confirm that these early EA82T engines (Aus spec) use NGK BPR6ES-II spark plugs . It turns out that my engine has BP6ES plugs in it , thinking it had BPR6ES ones I bought a set of BP7ES's so I could try resister and non resister plugs . I swaped the BP7ES's for BPR7ES's but haven't got around to trying them yet .

I was hoping not to have to use an aftermarket engine management system but if the dizzy doesn't make a sizable improvement I may not have much choice . If I have to at least I can use the later systems crank angle sensor and transister and have options with one dual or four coils . Possibly a double ended coil with a waste spark system .
Also opens up choices with larger injectors . Vipec V44's look like good things .

Work please dizzy , cheers Adrian .

with the plugs the manual seems to leave it up to the individual tuner with the three spark plug options in NGK, with & without Resistor - not real helpful are they ? Not a great deal of difference noticed when I got a working diaphragm but noticeable. Is this the same dizzy, spark plug choice and TPSwitch you ran with the previous motor? with the spider manifold etc?

Yes all same , which NGK's I don't remember .

Actually the feller doing the actuator just rang me up , needed Visa number , and to say that the actuator I supplied was quite stiff . He said mostly the diaphragms go stiff and brittle and then split/leak .

The blue colour is a bit gaudy for my old bus so it'll come back black .

So other than leads or maybe the coil I'm not sure whats up the wall , definitely should run better than it does . By that I don't mean the agricultural engine design , I mean the stuff controlling ignition and fueling .
The turbo has never been the same since I fixed the water line leak so whatever went pear shaped there isn't helping .

Cheers A .

The actuator was posted back to me this afternoon and was fitted early this evening .
It made everything a bit smoother and torquier and I think the fuel consumption will improve a little as well .

It still has a very slight miss and a slightly hunting idle at times .
I'll be busy work wise until Sunday afternoon and then I'll get a mechanic friend of mine to go over the leads and check resistance levels . The coil should also be checked and compared with the early spare EA82T coil I have .
I'd like to see exactly where the timing is and maybe advance it up a tad to see if it helps .

I think this engine is choking on that tiny turbine and housing but that won't be forever .
I'm checking up on larger hose tail injectors but there doesn't seem to be a lot available in the 370cc range with high resistance , most are low resistance peak and hold types that require an in line resistor .
I think std squirters are around the 230-250cc size so quite limiting .
Also checking up on twin tower coils though four singles would make for the shortest leads .

In time , cheers A .

time to start a new thread detailing what is different to your old clagged out EA82T and this one

Does anyone have the part number for the cas style dizzy?

discopotato03 · Post by **discopotato03** » Sat Sep 05, 2009 7:30 pm

Yes from my 87 Factory WSM .

D4P86-01 or D4P84-03

I have a couple of them in the cave I'll check out later .

Lol the cave! Is there any part's the are worse for breaking or wearing on those dizzy's?
Thanx disco
