In need of a rebuilt distributor for my 1985 FJ60.

[FJ60Seth]

@FJ60Seth did you receive a recurved distributor from Jeff w/ a single port vacuum advance as you stated he could do for yours... and are you running it?

It has a good, original vacuum advance. Sadly it’s sitting on a shelf waiting to be installed.

Ah, mine is too.

I want to know where everyone ended up on this? Any progress?

I just finished installing a new mid-70's, Toyota US application, NipponDenso single diaphragm/single port advancer in the distributor from my '86 FJ60, which received a 3FE several years ago. I'm hoping to run it in my '71 FJ40 with '76 2F (no EGR). The '71 F 2-bbl. carburetor I'm using has had the appropriate ported vacuum added. The only unknown is the mechanical advance. I imagine it needs a re-curve. I'm hoping to find a thread in the FJ40/FJ55 tech section that will help me determine what springs to use.

And I quickly found the answer to my question here (Post #5) :

Dizzy questions-Electronic type

Just a couple of questions on my Toyota electronic distributor. I was setting the air gap with the aid of the Toyota factory manual. I had the dizzy removed from the engine for ease of gap adjustment. I was looking at the photo in my manual and noticed that on the cam rim is a small dot. There...

Thanks again to @FJ40Jim for his valuable insights!

An update:

I've successfully adapted several different new NipponDenso vacuum advancers to fit the '81 and later FJ40 distributors, as well as the FJ60 distributors. Here is the line-up so far:

- Single diaphragm with vacuum advance similar to the advance curve on the '77 2F distributors - mainly for earlier Land Cruisers without HAC

- Single diaphragm with vacuum advance similar to the main diaphragm advance curve on the '81 through '87 2F distributors - mainly for later Land Cruisers where the HAC system is not required (vehicles not normally driven at altitudes above 3,930 feet), or for later Land Cruisers not normally driven below 2,570 feet (where base timing can be advanced to compensate for high altitude)

I'm currently adapting several good used NipponDenso vacuum advancers for the following:

- Dual diaphragm with vacuum advance and HAC similar to the advance curves on the '78 through '80 2F distributors - mainly for '79 Land Cruisers with HAS and '80 Land Cruisers with HAC

And every once in a while I have good used '81 through '87 2F dual diaphragm advancers available.

Another update:

I'm just now wrapping up a modification to a non-Land Cruiser dual diaphragm NipponDenso advancer. Later today I'll be installing it into a freshly refurbished '79 2F distributor for another MUD member. I'll post some photos when I'm done.

This is the advancer I'm using:

- Dual diaphragm with vacuum advance and HAC similar to the advance curves on the '78 through '80 2F distributors - mainly for '79 Land Cruisers with HAS and '80 Land Cruisers with HAC

Unfortunately it's the only good dual diaphragm advancer I have with a curve suitable for the '78 through '80 distributors. I haven't been able to find a source for new advancers from the same vehicle, but I'll keep looking.

On the positive side, I still have more than 20 of these, all brand new NipponDenso advancers:

- Single diaphragm with vacuum advance similar to the main diaphragm advance curve on the '81 through '87 2F distributors - mainly for later Land Cruisers where the HAC system is not required (vehicles not normally driven at altitudes above 3,930 feet), or for later Land Cruisers not normally driven below 2,570 feet (where base timing can be advanced to compensate for high altitude)
