Man-A-Fre Hi-Performance 2F & 3F Engines? (1 Viewer)

[rusty_tlc]

Just me, but I would love to have a MAF performance 2F. I've heard great things about the builder. The 2F in my 40 runs excellent, but it's tired, and if the rebuild fairy handed me a MAF performance 2F, I'd run it happily and put a MAF sticker on the bumper.

I agree with Rusty, that the shipping is the deal killer. There is a local shop to me with an excellent rep for 2Fs as well, and I'll start there first. if I lived near MAF, I be happy to run their motor.

I'm going to disagree with Rusty about the Weber. The motor always ran rich no matter what I did. I ended up giving it away and going back to a desmogged Aisin. His truck runs well, though, so maybe it was me.

Someday I'm going to have to figure out which Weber I have on mine. I had a shop install it 12 or 13 years ago and can't remember which one I bought. I also haven't done anything to it other than hose it off with carb cleaner a couple of times a year. Correction, I had to tighten up the adapter plate once.

The 2F is a good motor. I just don't see paying Man-a-fre more money to do something a good machinist will do.

I rebuilt my 2F something like 8-9 years ago using the machine shop that Cruiser Outfitters used to use (unfortunatly, the machine shop has gone out of business). They did all of the good things to the motor ie balanced, decked the head, etc. And the bill from the shop was liess than $2000. I didn't up the compression much, because I Wanted to be able to run regular fuel. HIgh octane is for sports cars with a Land Cruiser definitly ISN'T.

Anyhow, there is nothing that you can do to a 2F that you can't do to any other motor. It's all common performance tricks.

My suggestion is to call the service manager at your local toyota dealership and ask him or her what machine shop they send their blocks to be rebuilt at. Then call the shop yourself and ask them about rebuilding the motor.

One MAF motor I pulled the head on had a closed chamber head and domed pistons with custom hand ground notches cut into the piston tops for valve clearance.........

I don't have any machine shops in my area that would do that....

So that's like a cheap way to get crazy hi-compression?
Sweet.

Yeah, I wish mine had one of your desmogged carbs on it

Thanks for the input guys,

I have a 75 FJ 40 and it is totally stock exept for an old chevy V8 conversion ( probobly converted back in the early 80's) hooked up to the original 4 speed trans. I don't plan to do rock crawling or anything like that , I just want a quiet , smooth but powerful FJ 40 that will run 80-90 MPH on the freeway (Relaxed) meaning to say not SCREEMING like mine does right now at 55 or 60 MPH.

I also hered from Proffits Cruisers that a GM 5.3 with a 4L60E Automatic trans conversion will do about 20-22 MPG. Maybe this is a better way to go?

It's the gearing making it spin so fast at those speeds.

With that said, that's way too fast for an FJ40 regardless of motor. You are driving a tall, shortwheelbase light duty truck that is not safe or appropriate to even approach the speeds you are talking about. 65 is about it with occasional 70s. There will be tons of guys to say they drive theirs at 80 all the time, but they are kidding themselves if they think that's safe.

With Land Cruisers generally and FJ40s in particular, learn to slow down and enjoy the ride. If you want to go fast, get a sedan that's made for that.

Is there really such a thing as a "high performance " 2F 3F? I din't think you could make either one of those turds anything but "High consumption". I like mine for a toy and it will idle at 400 rpm, but if you want performance by a SBC and a torque-splliter ranger box and don't look back.

You can't polish a turd.

 

[josemari]

I am not planning on going those speeds all the time . You are right that is fast for the FJ 40 and my average speed on the freeway would be 60-70 mph , but I still would want it to be able to go 80-90 MPH on the freeway (Relaxed) that way it will feel really nice at 60-70 mph with lower RPM's.

They aren't that bad! As an off road motor, they totally rock. That low RPM grunt is perfect for wheeling in the west. You really need to feel it to appreciate it. If you wheel in mud all the time, I can see where you would want Chevy power.

To be honest, I don't really feel the need for a "high performance" 2F either. Stock performance is fine. If I were doing a rebuild, I'd want stock, optimized performance, and I'd be looking to keep that low RPM grunt, and also keep the nearly bullet proof reliability of the motor. Remember 2Fs will easily go to 300k miles and very few SBC Chevy motors will do half that.

There is a great thread on the "best" 2F on this site, with lots of great ideas from JimC and others. Check that out for more info.

I have one that I purchased directly from the rebuilder. So it's not "technically" from MAF but it's built the same by the same people that build them for MAF. For matters of fairness I can't say who they are. It's a good engine, it runs very strong and I'm sure would / will run better once I get my Fuel Injection worked out.

So I like mine. I'll give it and a half out of 4.

How many $s?

 

[msahr]

By the time I bought the engine, all the extra bits (header, mean green starter, DUI dizzy, Turbo City EFI kit, power steering, etc)...


Way too damn much. Probably $4000 easy. There's a bunch of labor in there from 2 hack shops as well.

4K! what a deal

 

[msahr]

4K! what a deal

uh wait... probably should revise that a little. OK a LOT.

2800 rebuilt engine
100 core
800 or so all the little bits
1800 for EFI kit
1500 for "installation"
ANOTHER 1500 for more "installation"

oh hell never mind. It's too depressing to add more.

Yeah, pushing 10 I wager..............

4WD Toyota Owner magazine did a feature on a photographer who uses an FJ40 with MAF hi-po 2F in it and not only did he love it, we were impressed as well. Powerful and smooth.

Here's a link of my Cruiser with a 6 cylinder we put in. 3 years of serious abuse and still running strong. This was last weekend on 7 mile in Colorado. This engine has a HP Cam, 120lb valve springs, Milled head, DUI distributer, and TBI from a Chevy 4.3.

That sounds about right.

How about some pics of the engine.

ooohhhh... I love the sound of a healthy 2F...
