Pertronix or Full Electronic Distributor

[Solace in Solitude]

I'm looking forward to reading your experience at altitude. I live in Cuenca, Ecuador, 8,440 ft. and frequently go 12-14,000 ft and it has no power. It is frustrating as the little 2.0L fuel injected cars just zip by me, and I pay a penalty for having such a large engine ($700 a year because it is 4.2L and the baseline engine size is 1.6L). Are you running an Aisan carburetor? Did you change to the high altitude jets? The final question is which distributor did you go with as you refer to three available. Thanks, I appreciate your candor.

Last question first... For the correct DUI see my post HERE, I think it’s post #9.

I have two Aisan carbs... one rebuilt by Jim and one rebuilt by Mark. Jim’s rebuild was great. Mark rebuilt my spare and added some, as he said, “performance enhancements”... Viagra? Mark’s seems to help 44 generate more power. But, to be fair, I never ran Jim’s with the DUI installed... so, my dissy probably had a vacuum leak at the time.

I haven’t changed the jets that Mark installed for my 2400’ altitude.

Before I finally found the dissy vacuum leak, I asked the experts on MUD and it was suggested that I advance timing a few degrees, as 44 became sluggish at altitude. This is what finally made me realize the vac advance might be leaking.

I had started having significant power loss at 5 or 6k’... I doubt I could have climbed at 12-14k’...

I’ll certainly post my trip on my thread... it’s gonna be mid-May or so before I go... too cold to camp up there right now... at least, it’s too cold for me!!

I’m planning to hike to various 11k’+ summits... but, hope to also find a road that allows me to drive over 11k’... I’d like to see how she does.

There’s a MUDder in Colorado, @subzali, who has frequently posted about his FJ40 experiences at altitude. You might search they his posts.

Thanks. After reading and responding I went looking and found numerous offerings for the DUI from $200 to $400. Good to know which one worked for you. I can appreciate not liking cold. Six years of retirement so far and never having to wear a jacket. Down here you have to get up around 18K feet to get snow. Since I'm only 3* South of the Equator it is the altitude that moderates the temperature. If you go down the mountain to Guayaquil it is always insufferably hot and humid.

18k is too high for me... I like oxygen too much!!

I don’t mind moderate cold... but, not when I’m camping!!

Any 1.6L econobox can probably pass me going up a 6%-7% grade at 6000-12000 feet. There are no paved passes and few paved roads above 12000’ in Colorado so the econoboxes will be stuck at the trailhead while I motor on up to 14000+’ at FJ40 speed

I know my 1.8L Corolla can burn the crap out of my FJ40 on any paved road!

But at those altitudes you shouldn’t be worried about going fast anyway unless you’re running the Pikes Peak Hill Climb:

I see the Summit price is the same product and price as Performance Distributors. Not sure what JTO is selling. No, not driving very fast and most of the mountain highway is two lane, no shoulder, 8 inch tall curb for water control. No guardrails and maniac drivers. That's where I see the small cars zooming past me. I'm usually running around 50 mph. There are so many switchbacks it takes about nine hours to cover 400 km. Which I hope to be doing very soon, today makes three months since the bodywork started, maybe one or two more weeks, fingers crossed.

50 mph above 12,000 feet sounds pretty dang good to me. Probably running on the rich side.

When I bought this rig in September 2015 I was looking for a kit to rebuild the carb. We don't have auto parts stores like you have in the USA. This guy sells bearings, this guy sells spark plugs, etc. A fellow who sells some Toyota parts had the kit, then he goes in the back and comes out with a brand new Aisan carb. This is a non-smog carb and cost me $290. I put it on the car, I adjusted the idle and haven't touched it since. I did ask the mechanic last June to change the jets. The secondary mechanic guffawed that the difference in altitude wouldn't have any effect. Later he said he changed them, I don't think so. Anyway the same day we checked compression and found #1 was pretty much dead. Into the shop in mid-July for steering, brakes and a valve job. Head came off, some scuffing on the walls, out came the motor. Four months later I have a rebuilt engine and some tie rods. Used it for three weeks and drove it up to Quito where it has been for three months for bodywork. I was actually disappointed in the difference in power, it really wasn't much. But I still have never paper clipped the secondary to see if it is actually kicking in. When it comes home I will do the knuckles, pinion seals and brakes (I have FJ45 power drums) as I haven't been able to locate a disc brake axle.

Matt,
What kind of rotor did you put on this dizzy? I put a Pertronix I in mine, and the anti-overspin rotor wont work. Installed a standard OEM rotor but thinking it might be contacting the dizzy cap contacts a little bit.

Since the Pertronix does not come as a "kit" including a cap and rotor, you just use OEM stuff.

I installed a 1977 USA spec. FJ40 Rotor 19102-45060 ( Now Supersedes to a 19102-45150 )

That' s correct The pentronix Kit is meant to be compatable with OEM parts ,

BUT ,
in the case of the 19101-61180 dist. assy there is a interference issue on the back side of the Rotor with the two little
" Antenna Things "

as i recall also , the round magnetic pick-up can be put on upside down real easy so make sure its right side Up

the 61180's cap part# is 19101-45060 this is the same for the Saudi Spec. unit and a 1977 USA Unit

This is a Dealership Parts Dept. Print Media Cataloger from 1997 , The information going back to the early 1960's is Solid

Is there a specific “weird” Pertronix kit to be used on distributor 19100-61180? Referencing this photo blog from previous ih8mud threads...

I have the 1990 version of that catalog. Very useful.

@Brybrys1978
I installed the 191000-61180 dizzy (from cityracer) and used the "PerTronix 91662 Ignitor II Adaptive Dwell Control Toyota 6 cyl". I had to remove the dust cover under the cap but it fit and works fine. if you go to the pertronix site they have a search for dizzy model to tell you which one to buy.
Then again maybe I should have bought the 19102-43060 that the dealership parts catalog was referring to^^.

I'm still trying to figure out if I needed the resister and igniter I removed.....

I would like to know what you decide and how it turned out!

 

[Brybrys1978]

So if my research is correct, the
191000-61180 distributor (I’m trying to bring that term back in vogue) is essentially a 1976-1977 distributor which requires the following kit from the pertronix website:
