2F - What is that ???

[Stupid frnch jackasS]

Look what I have in my barn now !!!
Well, my buddy just bought a clean 1982 FJ40 w/ H41 & PS, and I have a few questions about what I couldn't find in the archives...

1. what is the avg. / acceptable oil consupmtion for a 2F

2. are this carb. and headers worth crap ? (pics to follow)

The FJ will be used for on/ off road duties, and my friend is not looking for more power or anything, just wants a smooth running engine that works fine both on & off road, doesn't burn too much unnecessary fuel and doesn't overstress the engine...
By now the engine is very hesitant when you push the accelerator quick, and seems to like the upper revs better than the lows. I would like to hear the wisdom about how the carb and headers affect the engine behaviour, and any related advice.
shoulc we go back to stock carb and manifold ?

The PO also said he had to adjust ignition at least a few times... Is this normal and can this be fixed ?

As you probably guessed, I'm pretty much illiterate for petrol engines in general, and 2F in particular so I want to hear just every piece of advice about this...

Thanks !!!

holley carb... couldn't find anything else written on it other than a buch of patents number...

Theres also a strange cylinder between the MC and final brake lines... what is that ?

First off, you've been here long enough to know that you should try one of these first!!

Second, use that button to search for "headers", "Holley", "carb" and "proportioning valve". Should give you a start!!

That's the proportioning valve in the line that goes to the rear brake system. It "regulates" the brake pressure that goes to the rear vs. the front brakes. You can find more details by searching on "proportioning valve".

1982 FJ40 w/ H41

If the transfer case is a split case like that used in the US, the low gear is close to that of the older "3-speed" transfer case.

This weekend I hope to finish the install of my H41 and 3-speed transfer case into my '76 FJ40. For now I'm leaving the 4.11 diffs in the axles, but will later install the 3.70s from the '83 FJ60 I just parted out. Even with 3.70s, the final ratio will be over 40:1, more than a 30% increase over stock, if I left it with 4.11s, the ratio would be over 45:1, almost 50% better than stock. I'm leaning towards the 3.70s, out here in Nevada I'd like to be able to cruise comfortably (if there is such a definition of comfortable with an FJ40) at 70 mph.

Do you know what gearing you have in the diffs in your '82?

how about a pic of the WHOLE 40

Hey, I know about the search button, and use it often, but just looking at the parts and reading the thread, I can't find what he has exactly among the bunch of holley carbs or headers available Remember, that's only the second F engine I see, and when I saw the first one 3 yrs ago I really didn't pay any attention... Come on...

Thanks for the prop. valve though

I didn't know such thing existed. my '83 has nothing like that...

Yep, it's a split case
The axles are 3.70, I had to check them quick because there was apprently a big question about it... On the highway at 55mph the (aftermarket) tach read 3200 with 33"... Actually it was way off, I guess it came from a 4 cyl. and hadn't been calibrated

appreciate the clean fender cutting...

See now, the first thing you do is dump that Holley, and install a factory Aisin. Then you will have on and off-road performance and mileage. The timing should be set at around 7-9deg. BTDC
depending on your altitude. Above 2500 ft, then try 9-12 deg BTDC.
Average oil consumption is not very much on a good solid engine. Maybe 1/2 to 1 full qt. btween changes. (3Kmiles)
Should hold about 7qts. of oil maybe a little more depending on the filter you use. Change the coolant as well. And the rake fluid if it sat for more than a couple of months. Change the all the drivetrain fluids for sure.

My stock '84 FJ60 has 33s (BFG 33X9.50s are 32 inches tall) with 3.70s. My tach reads 2,900 rpm at 75 mph.

Damn, we scramble all over each other for a "B" or "H" series and you are excited about an "F" series.

You are a Jackass!



That thing is sweet! Did you get a good deal on it?

Thanks for the info ! What do you think about the headers ? Obviously a full service will be done before he really starts driving it some.

Yup, I did my math and recalibrated the tach, and it feels a lot better not reading 4000 when you're actually at 2700

He he, I already have 2 B and 1 3B engines in my barn

the price was not really cheap, but it looks really super clean aside from a few details but no biggie. The big concern is the engine tuneup...

Again, it's not mine, but I can play with it until next weekend when it leaves for its real new home... The 2F is starting to grow on me, feels like a racing tractor when compared to a B

My buddy said it felt like it was running lean from the sound of it when freewheeling... Anybody know where is the mixture screw on the carb ? a tip on the idle would be cool, too, since I don't really have a stock carb handy right now... can I adjust the fuel/air ratio by just guessing the smell of the exhaust ?

Most rigs after 1980 should have that jigger! (prop. valve)

[BJ On Roids]

looks like a cool rig!

cage looks sorta like mine

[4Cruisers]

The proportioning valve in general (?) is only on Land Cruisers with front disc brakes. Does your '83 have drums up front, or did even the European FJs all have discs up front by then?

The Toyota trucks and 4-Runners, and maybe later Land Cruisers, have load-sensing proportioning valves mounted on the frame near the rear axles.

John

[kruzrtek]

The mixture screw on the Holleys is usually horizontal in the base plate. Some models(depending on year) had them vertical, but not often.
Just look around the base of the carb for a couple of screws about 2 inches apart from each other horizontally. They may have a pointed style head with a slot for a flathead scredriver.
Out should richen it up. In should lean it out. Unless they installed the PV in backwards then its opposite. But the smell and drive test is great to do. You'll want it so that it doesn't burn your throat to breathe. That is way past the richness of burning eyes!!

Good luck. If you need help, email me. I am only on POR at night.

If you could get me a pic of the front of the carb at the bottom.
And a pic of the bottom of the carb in the back at the base, I'll tell you where the mixture screws are. The screws on either side of the metering block were used for somehwhat of a mixture adjustment for a while, but that carb looks a little later than that era. I basically just need pics of all angles and levels of that Holley to be sure.

Screw that.
The Holley is a great carb.
Can work equally as well as an Asin in off camber situations and will give LOTS more power.

Take the holley, put a center hung float bowl on it. (I'll take pics of my 72 tomorrow night and show you what it looks like) jet it properly and enjoy..

The factory Asin will get better mileage. But only because is sacrificies performance...



I whole heartedly agree with the timing tho
