2F Versus a 3FE

[DieselFJ]

I thought I would throw this out and see what you guys think. I rebuilt a 2F and have not installed it in my project 70FJ40 yet. I have been doing some thinking and I have been considering buying and rebuilding a 3FE and putting it in my 40 instead of the 2F. What do you guys think? Would it be worth the power increase and the gas mileage increase? Would I be able to sell the 2F for a reasonable price?

IHere is what is on the rebuilt 2F.

Engine -- .20 rebore,
new pistons
chrome rings
polished crank
new rod and main bearings
new lifters
new cam
new exhaust valves and reground intake(complete head rebuild)
oil pump
plugs, cap, wire, rotor, pcv
planed exhaust and intake manifold
new water pump, every hose, thermostat, belts,
smog pump(aftermarket)
stock powersteering pump
a/c compressor(original mount)
rebuilt stock 2F(Asiain) carb
I am sure I am missing some items, but you get the idea.

Anyway please let me know what you think

Thanks
Scott

If you have a complete 3FE with ALL of the electronics, wiring harness, etc, I would DEFINITLY put that in instead of a 2F. EFI is the only way to go...

 

[DieselFJ]

I don't have a 3FE right now, but I would just start looking for a complete setup.

You are smoking the pipe.



3FE is a great motor for the 62 but far from perfect. A much better goal would be a 3F conversion without all the BS with the 3FE. IF you have a full 62 with all the crap and IF you can hook it all into a 40 series it would be a good achievement. It has been done before but there is not enough gaine for the pain.

The 2F's rebuilt, drop it in, your Cruiser will be up and running a lot sooner.

I'm running a 3FE in an FJ60. The 3FE hooked to a manual transmission is a good combination, but you loose some of the low end torque. There are times when, at low idle the 3FE will bog down when a 2F would not. There will be no significant mileage gain, if any.

 

[Landpimp]

do the 2F.

In that case, just do the 2F.
Make sure you have a well built carb.

3FE head with injection on the .20 2F block would be quite the stump puller.... you just can't argue with a long runner EFI manifold when it comes to torque.

 

[labartonmd]

Power is useless unless it can be used to advantage. If you plan to bolt it to the stock 3 spd in your FJ40 you will see no real world improvement because the stock 3 spd ratios just plain suck for a daily driver. A tranny swap behind the 2F will be MUCH more user friendly than a motor swap with the stock 3 spd. My 0.02.

If you are wanting to do it to gain fuel injection I would look into TBI on the 2F the 3FE is an ok motor but not worth the headache, IMO

 

[CruisinGA]

Get a carb from Jim C or Mark, and drop in the 2F.

My worn out F with Jim C carb is more predictable than the EFI in my 93 80.

Not as much power or ability to run on incline, but that hasn't prevented me from going anywhere yet.


The 3fe head on 2F block sounds interesting, just heard too many 3FE fuel system horror stories from David to really want it.

 

[DieselFJ]

I did the rebuild on the carb, which I have done many times on many cruisers, so I know how reliable they are. As for the trans and t-case I have a h55f 5-speed and split trans behind the motor. I love the 2F, I have had great luck with the motor. With gas prices up I thought maybe I could gain some fuel economy from the 3FE. I also wouldn't mind a little power increase, but as everyone knows when you get the power increase you tend to use it which lowers the gas mileage.

Thanks for all of the input, there is nothing like a good discussion to help see the positives and negatives. As for what I am doing, I believe I will just use the 2F. I spent too much time as well as top quality parts to get this motor to the condition it is in.

Really, it brings tears to my eyes just looking at the beauty

Thanks

or

My approach with Landcruisers matches my philosophy for life.

K.I.S.S. Which was pounded into me at Parris Island.

I would like to put a 1FZ into my 72 40, but there's too much electrical crap, plus finding a manual transmision is a pain too. Then there's cost and labor.

I've been working on 2F's since I was 16, I'm 31 now. They work well enough and most repairs are really simple. Besides I really like the way they sound. Cannot beat an old straight 6.


How much power do you really expect to get out of fuel injection?

LandCruisers were originally designed to be reliable uncomplicated utilitarian vehicles.

I like them that way.

 

[DieselFJ]

I was thinking another 50 hp would nice for driveability, but this won't be my dd. I have been working on 2F motors for a long time as well, so I know pretty much all the in and outs. I have done some work on the 3FE, but not nearly enough to know all of the quirks. I think the 2F has my vote as well.

2F/H55F - SWEET! Do that. Your rebuilt 2F is a thing of beauty.

And this is coming from a 3FE addict. I love the 3FE, except for the FPR, which is evil incarnate.

 

[DieselFJ]

Thanks, It is good to hear some 2F fans out there, I have been defending them for a long time, I guess I was feeling the pressure for more horsepower.

By the way I have two misprints in the original post, my cruiser is a 79, and the bore on the block is 0.020, sometimes I type too fast.

[DocB]

Do the 3FE and I will buy your rebuilt 2F , you know, just to help you out and get it out of your way.

 

[DieselFJ]

Is that your cruiser? Where are you located, it looks alot like Utah.

I think everyone has convinced me that the 2F is the way to go, but maybe a 3FE on my next project.

[DieselFJ]

DocB, I just noticed you location, that does not look much like Amarillo TX.

Next project should be a chopped FJ55 buggy with a 3FE. Ohhhh yeaaahhhhh!


3FE POWAHH!
