Just bought a 2F for my 45 just how slow is this engine I already drive a Hilux diesel I know what slow is
has anyone supercharged a 2f?

Makes a bit more sense to turbocharge/supercharge in OZ where Toyota parts are plentiful and other options aren't as cheap.
I'd like to force induct a 1FZ in my LV. It has an aluminum head, four valves, MPFI, computer controlled ignition with a knock sensor and a 7 main block. Much better suited to surviving long term boost.
It'd be cool, but I have a hard time justifying it when there are dozens of cheaper, easier and more powerful options, many with arguably equal reliability.
You planning on sucking through a carb with that Pontiac supercharger?

No not going to to suck through the charger. I am going to blow through the TBI.
Follow the link fuzzy logic put up. Apparently more than one person is doing an eaton m-90 with 6-8lbs of boost.

I was talking to the OP who doesn't want any wires. I'm not seeing a whole lot of info in Fuzzy's link.
Yeah. I should know better.
why waste your time with a 2f just go 2jzgte maybe 800 hp with a few bucks. 6-8 pounds aint worth it, it a tough engine but you start boosting it probaly wont be reliable over time.

Yes I was think of putting a carb on top the supercharger. It is a trail rig. It might see road a little but mainly offroad I know I could put gears in the rear end I just don't want to sacrifice top speed.

nice catch, I was debating whether the pack animal had a "C" in there somewhere...
I agree. It's much more cost-effective to use a factory turbo engine, than to turbo a stock 2F. (I will concede that there were no stated alterations to the internals of the 2F, so I'm assuming stock). If this were part of some grander, radical rebuild of the motor (as is the case for JoeyG1973's rig) you may as well have your cake and eat it too.
Any 2F you get will be used, and in varying stages of tired, all the more likely to break down under the strain of the added boost, especially when you need the truck to be running the most. One of the F-series motor's strongest points is its simplicity, in a modern era of overly-complex tech, that motor is a pillar of rugged dependability, adding a turbo just doesn't strike me as being apropos, or cost-effective.
Ultimately, it's your dime, and if you want to do it, I won't stop you, but I wouldn't do it.

Ok I wasn't sure what everyone thought of supercharging it. I want it to be reliable as I don't want to be stranded on the trail. I have a h42 hooked up to a three speed transfercase. I have the stock 4.10 in it and have 40" iroks I would like it to be able to go about 55mph. if I stuck 4.88 in it is that enough for low end grunt and what would my top speed be? I would think the 5.29 would be a little week becouse of the size of the pinion is that true?
my turbo troopy has now done over 5000km not many as its only my weekend toy and well my weekends have been packed since i finished it
i run 6psi these days but 1 ran it on 12psi for a 600km round trip performed perfectly but ran warm so i dropped it down to 6 to keep everything happy

Yes, that is correct. As the ratio goes lower, the pinion gets weaker. But worse, as the gear ratio goes lower AND the tire gets larger, now you've really got a dilemma (example= 20 percent lower gear with 20 percent larger tire equals 40 percent weaker vehicle)!!!

Now, back to the question of boost; Downey was in business for 39 years, and most of the engines we blew to kingdom come while testing forced induction systems were blown up before many of you were born. 3 to 5 lbs is probably ok if you have OEM internals. 6-10 lbs is probably ok if you have forged pistons and heavier duty wrist pins and connecting rods. The big problem is 3-5 lbs of boost equals about the same performance gain as installing a Header ($2-300.00 for Header, $2-3,000.00 for Supercharget/Turbo). My guess is that those who have found success with forced induction are those who bought a factory installed unit, not aftermarket add-on!!!
matt.mcinnes tubo'd a 2F (w/3FE head) and spent a lot of time documenting it including dyno runs and all. It's an interesting read... and long

It's not SC, but a good example of what one can do to the motor to support the power, plus hard data to back it up.
There's some links buried in the thread to youtube videos - pretty crazy those guys down under.

Ok so it looks like unless you mod the internals it's not worth it for the max boost you can have reliably. Are there any gears for the transfercase or transmission to gear it down ?
Also buried you'll find how many AUS$$s he had into it. Do yourself a favor and find a nice used vortec 5.7. You'll save weight, gas, money and broken metal bits.
I'm guessing Mr. Downey's advice is worth infinitely more than you paid for it.

Slowwly but surely...

Interesting thread. Seems that there are two trains of thought on the subject, and that most are in favor of not. Having come from a hot rodding background comprised of both gas and diesel engines, I would like to add my two cents worth. I have read a lot of the positives and negatives of both the SC and turbo. Here are my observations: #1. They are expensive. #2. To be able to use a SC or turbo on a gasoline motor, to it's full potential, you must build the motor right. #3. That is expensive.
However, I totally understand the quest for more power, and it is something that I think about regualarly as I finalize the plans for the build of my cruiser while keeping it Toyota. Here are my musings: Why not buy a high performance rebuild from Man-A-Fre:MAF Hi-Performance 2F & 3F Engines Reviewed here:http://www.4wheeloffroad.com And here:Man-A-Fre Service Department If this didn't satisfy your need for extra power, it would certainly give you the internals you would need to add extra boost. Or you could put in a Toyota diesel with a turbo for probably about the same money that you could buy a hi-performance motor and a turbo for, but then you would probably have to mod that on top of the four or five grand that you would already have in it to get the kind of perfomance you want. ( Not that I don't love diesels... I have a Dodge Cummins that will do 0-60 in 6.3 and the quarter mile in the 14s.

Mr. twoturtlesracing, don't forget to factor-in the weight difference between the 800 lb. Toyota 6 cyl. and the 550 lb SBC.
so, 12 lbs of boost and 5K rpm is a bad idea then..
Hmm, guess I'll just have to stop doing it then..
that's what i was just thinking... and Flaminbandit's ran fine on 12... your both soft tho, the late Andrewfarmer was pulling 7000rpm
both "tired" motors from what i remember. must be the propaine.
also i've driven in both, with 5 pound of boost, and a 2f with headers... and there is no way their even close to comparable... 5 pound makes for awesome 3rd gear pull... headers... don't.
