I'm talking about wheeling in a 3 ton brick. Mini truck, etc: Absolutely a manual.
Anyway don't want to sidetrack a thread yet again as the lame "parts slinger" that I am.
Someone in the know post the difference driving experience in a 5sp 1FZ and a 5sp diesel
This is a good point. I would like to hear from someone that is in the known in the driving difference between the auto 1FZ and 5spd 1FZ. We know that in the us trucks with auto/torque converter/fulltime 4wd/viscous coupler we see a 30+% loss at the wheels. Does the power feel different with the 5spd? If you don't have as much loss, you're going to have better power and better mpg's.

I have driven both an automatic 80 and a 5speed 80. I would have to say driving around in the 5speed is a completely different animal. I love having control over how it drives. Having a 5 speed with the 1FZ is a fun combo.. Below is a picture of my old 80 in Colombia.

You dont feel the power loss trust me on this. you can actually spin the tires.. Its a different animal trust me on that!!
Yeah I would think a huge amount of that power loss is in the transmission and in the 4spd to 5spd (a343-a750) thread, I showed the Toyota documents that Toyota worked hard with the a750 to eliminate something like 11-13% of that loss. If the 5spd was 10% loss compared to the auto 30% you would feel like you added 42hp, and that is a lot with a 212hp truck.

easiest way to gain HP without rebuilding the engine for forced induction.. I could only imagine your turbo'd cruiser with a 5 speed on it..
My 1Fzj55 is 1000lbs less than my fzj80 and its rough equivalent power to weight ratio = to a 45hp gain.........and its VERY noticeable.
fzj40 with a 5 speed is my next project.
Best place to source the h151f on the cheap is Australia right now due to the exchange rate. 25% stronger USD. ive been seeing them for $500-700 at the wreckers. bells for 1fz are $75.
Why?
H55 seems a better choice, given availability.
H55
4.85 1st
.85 OD
H150F
4.529 1st
.881 OD
Considering split case gear options and abundance, I don't see the benefit in the H15XFs, but my curiosity is oiqued.
If you insist, I've an H150F/HF1A I'd entertain, say $6k for....
You're supposed to be carrying the H55 torch!!
Even have a bell housing with your name on it....
Tread cautiously with wreckers in Oz, as some have vision impairment when it comes to inspection after a collision, or in general, and may miss cracks in either the BH, case, or shaft housings.
Freight expenses can be absorbent, as well.
Having spent time communicating with FloridaFJ80, I believe the SA market holds greater promise as a resource for, due to a similar exchange rate and more economical freight arrangements.
Plus, he's wired in and desires to maintain a reputation in the community, so accuracy in representing will be of greater importance.

Easier install I guess. I actually already have an H55 and Toybox with appropriate adapter if the project gets off the ground

There will always be better prices somewhere, but keep in mind that here your looking at a complete swap with all or most involved. Plus you have the backing and support of a mud member.
In Colombia it is very common to see FJ40 series rig with a 1FZ swap. Here is a prime example. This one in particular they took the complete drive train from a 70 series and put it on a fj43. (Engine, tranny, transfer and axles) Price in USD $10,000.

I also can bring back full 1FZ carb'd motors for these type of swaps. This is the Colombian way of dropping some awesome power to a 40 without the need of a v8 for all you Toyota Purists!
MUD for me is home on the net. I am a cruiser addict. I am willing to put my 10 years of membership on the line to back up a sale. I didnt just join last week. So in other words I am here for the long haul and if I can fuel my "addiction" somehow by all means. I am putting up all my trust worthy connections and offering it to the mud community. I can help you source anything for your rig, and if you wanted that 1FZ'd FJ43, I would take care of everything associated with buying it in Colombia, and handing you the keys in Miami and of course everything in between. You would never have to leave the US. So that $10k rig in Colombia becomes $17k delivered in Miami. Still a lot cheaper than for what these are selling for stateside these days.
How about $300 for a part time case and Hubs? That is if the HF1A bolts to the auto tranny.

Keep in mind, the price may not change much and its really due to all the same costs associated in bringing the case. In other words, removing the transfer case only reduces it some as the rest of the costs are constant.
I understand what you are doing here. It is hard sometimes inflect sarcasm into your posts.
Thanks for putting the work in to get some 5 speeds in the U.S.
Thanks for putting the work in to get some 5 speeds in the U.S.If, being operative, it would, linkage would have to be fabbed for shifter, since it mounts on the transmission housing.
If part time auto is the goal, better to convert an HF2A(V), due to the lower gear ratio afforded with the crawler gears.
For that matter, even with the H151F, converted HF2A(V) should be given consideration, simply because it affords the lowest L gear possible (H150F, more specifically) with any Toyota combination for the 1FZ, as there are no lower gearset options for the HF1A, because the idler gear is part of the shaft and not removable.
Edited-
For comparison:
H151F
1st 4.081:1
2nd 2.294:1
3rd 1.491:1
4th 1:1
5th .881:1
Mark's HF2A (FZJ80)
4L 3:116:1
Compare that to the HF1A and HF2A's 2.488:1 and it's a significant improvement.

Does the clutch pedal mount to the existing pedal shaft? Would the conversion require a skinnier brake pedal? And I assume this requires fabbing hydraulic lines from the master to the slave?
