Has anybody completed or seen a 2FE conversion on an 80-series?

If so, is it worth the change if I have to replace the 3FE block out anyway?

I know it is a tight fit on a 60-series and I can't find info about an 80-series conversion.

Steve,
I don't know anything about the 2F or the 3FE but I wanted to be sure that we understand what it is that you are trying to accomplish. You currently have a 3FE engine. You want to replace the block with a 2F engine block and keep the head, intake, and fuel injection from the 3FE. Is this correct?

If yes, then read Pappy's build. He is doing the same thing in a 40 series. There are a lot of little details about the differences between the 2F block and the 3FE blocks that you will need to be aware of.

Yes Tom, that is the write-up. I think Pappy has a thread in the 40 section. He also has a thread on our local club section that covers more than the engine.

:grinpimp: The one day I drive over to the Eighty Section and I find you boys talking behind my back. Does that link still work? This is the link I've been giving out since Cumcast sucks: 3FEconversion.pdf

Big difference between an 80 and a 40 with this conversion.

Also, see the original question at:
3FE Cracked Piston

Yes, the link still works. I noticed the date of your article on the 2FE build was about 4 years go. How is the truck running after all these years?

Mike ... Mike ... Mike ... :flipoff2:

And for the record, I picked up the engine December 2006, not 4 years ago. The truck is another story.

So wait, Pappy. I have all the ingredients for this conversion and want to know you made it work. Don't let the naysayers like -B- get you down. If he is making fun of you, I think he has an FJCruiser in the garage.:D

Worse, he has a Tacoma in the garage. Mike just likes to, uh, encourage me. :grinpimp: Yep, my engine runs, but I figured most folks knew that: 11mb video

The 80 stays in the garage during the week. The LS gets the garage on weekends. The Tacoma stays outside now that my son drives it every day. I gave it to Ross because I would get violently ill each time I had to drive that ugly green truck.

I didn't realize it has only been 19 months :rolleyes: since your 3FE engine was finished. At my age, the months fly by quickly and the next thing you know someone wants to take away your keys and says you're too old to drive. When you finally get it running will you promise to swing by the retirement home and pick me up and take me for rides?

The reason I threw out this question was because in my search for a donor 3FE, I received an offer for a low mileage 2F engine out of a 1983 60-series for a good price.

I read the above referenced article as well as another one that detailed the installation of the 3FE head into a 60 series. I'm just weighing all my options before spending any cash.

So far, I haven't found anybody who has done the swap and/or determined if would be an improvement or not.

Steve---It should work, though. The most difficult part is the fuel and wiring systems which would remain exactly the same in your truck. Everything else is just details. The question is, would it make sufficient POWER to move the 80 down the freeway. I am fairly clear that a 2FE makes more torque than the 3FE, but I'm not sure it makes as much power.

I have a spare 3FE in my garage, and I just bought a 2F from an 85 in good shape. Since neither motor is in a truck, the motor build process should be straight forward. I'm looking at it as a long term project, and I'm not sure what truck will get it installed when I'm done. Putting it in the 40 looks like the most work, but also the safest because I don't really care that much about the 40, and I don't depend on it as one of my families' drivers.

Please post back up what you decide, as I'll be curious to follow your progress.

Pappy-that's a nice write up.
 
Thanks Andrew. Some day I'll finish it.

You are correct. Doing the 2F block in a FJ80 is much more straight forward than in a FJ40. The fuel and wires are all there. No EFI engineering needed. The rest of the issues have been resolved by Arron. The only question is will it fit under the hood. How do the dimensions on a 1FZ-FE compare to a 3FE?
 
I already pulled the head off my 3FE so I can't measure the distance between the top of the engine and the hood to see if would clear. The 2F block is approx. 2.5 inches taller according to measurements I've seen.

I was hoping somebody had done this to see if there was any improvement over the 3FE in such a heavy vehicle.

If anybody has a reasonably priced running complete 3FE in the Pacific Northwest, let me know.

The other question would be is how different torque and horsepower points would work with the A440F auto tranny.

Does anybody have these dimensions. I searched using several keywords and couldn't find an answer. Is it listed in the FSM?

Your build would probably move about anything down the road or trail.

I have not seen the engine dimensions or weight mentioned anywhere in the FSM or other Toyota manuals.

PM beno. He is using a complete 1FZ-FE long block as a coffee table. He should be able to give you those numbers... maybe weight too.

From an article I found titled "FJ62, Version 2F-E" by Arron Thompson, (Toyota Trails ?), it was noted that the 2F block is 2-1/8 inch taller than the 3F block.

Since the head is off my 3FE block, I had to calculate the clearance from the top of the engine to the bottom of the hood. My best guesstimate (while laying under the Land Cruiser and measuring with a tape measure) is that the 3FE has less than one inch of clearance with the hood.

So the best I can tell, unless one does a 2 inch body lift, it looks like the 2FE will not fit in the 80-series.
