ihz in a fj-40

[guenther65]

Hey guys,
Well with all the info i received from my last thread, I think I am going to go with the 1hz. I did notice a post by rick_d that the 1hz wont work on a left hand drive with the OE steering box. Can I go with a power steering box? I want to keep my baby as toyota as possible. Has any one delt with this. I don't want to plunck down the cash and have to go witha sagi set up. Does any one know the average mpg on the 1hz? Tons of questions! Thanks for all the info!

Why won't it work with the steering box? Do the manifolds hit?

 

[Pskhaat]

Why a 1HZ instead of a 2H which is a drop in. 1HZ a great engine don't get me wrong...

 

[guenther65]

I have read alot about the 1hz and it has about the same power as the 2f and with turbo and an intercooler it has almost 200 hp. I haven't heard to much about the 2h so i couldn't tell ya. I do plan to move to costa rica and I have read that it is a cruiser haven, with the 1hz a common engine. Easier to get parts. Do you know the power on a 2h? Any input would be great.

 

[rick_d]

both of you have seen a HZ (read: diesel) starter bolted to a bellhousing and block correct?

once you see this, you will immediatly understand the the giant starter is too close to the steering box on A FACTORY LEFT HAND DRIVE FJ40- this means ANY 40 series (or for that matter mini truck live axle ) conversion.

as I recall the best distance with good firewall tolerance is <3/8" w/o any shield- the engine kicks to the drivers side on start up (better) but backlash of the engine goes back to the box.

rotational parts vs fixed parts (engine vs steering) need a 5/8" min distance

you must also note a BJ42 starter has a different tilt that a 70 series - but sorry folks the bases are not the same HZ- 3B

Starter is low on left side (and back)

intake manifold is high on left side

air intake comes from right side over valve cover

exhaust routes on right side

The 3B we recently installed was very close to the starter, about a inch away. This was with the 3B positioned quite forward with about 8 inches between firewall and engine.

With the 1HZ we would be positoning more towards the rear for the clearance (closer to the firewall)and I suspect the small mini truck power steering box we used also adds some more room.

Great information!

One could use/change to a 60 series PS box to maintain all Toyota, such as this fellow has done. http://home.comcast.net/~dtay/1HZ_Swap.html
I believe the picture showing the PS box located on the framerail is on another thread in this forum. This would also afford the opportunity to ditch the 40 series center arm, and adopt the 70/60 series relay/tie rod setup.

Come on DT: Ya gotta finish that thing!

I've never seen a 1HZ that intimately except from the hood opening on Zepp's. 2H I just suggest often because 1) I wish I had one, and 2) it's a drop-in for the most part. I think the starter will interchange, and the exhaust is on the same side as the F series.

 

[Radd Cruisers]

I sure wish I could get a measurement from starter to frame rail with a level and tape, then I would know if we would have to go with the 60/70 series steering box.,

I read about this guys conversion a while back - while it's really cool, this is what changed my mind about a 1HZ in a 40...

It's just too long IMO...for a short wheelbase off-roader a 3B or better yet 13B-T are a better choice.

Just my .02...we all agree it's one sweet engine, I'd put one in a 55, 60 or 80 in a minute.

exhaust routes on right side[/QUOTE]


That was quite tight as we wrapped the exhaust down under the bell housing, there was however enough clearence once installed. Even with axle under full compression, there might of been about 1/2 inch or so.

I must agree with some of the pitfalls of the 1HZ, I will more than likely run into some snags. I can only hope they are small snags.

We hope to make a bolt on engine bracket for the engine mounts in order to keep the powder coated frame looking good, this also allows us to have them powder coated to match.

Hi Tucker...

I figure a turbo'd 1HZ into a 40 series troopy would be sweet!

There is mention from DT about the length of the combo he choose, on his website. He is using the 1HZ-H150F-HF1A combo, which I believe is considerably different from the 1HZ-H55F Split-Case combo. I do not have the measurements however.

DT, do you have the difference between the two?

Agent Orange (BJ42) of Calgary fame has a 13BT powerplant, and it is a sweet conversion.

Each combination has it's plus's and minus's for sure...

[guenther65]

So I could go with a 60/70 ps steering box and it would work? Sheldon from G&S suggested it. I now have a later model steering collum reedy for the p/s convertion. The combo that I want is the 1hz w/ h55f, I think it is shorter. She will be tight, but the power!!!

I totally agree w/ you on the 47 troopy or even a 45lwb - I guess it comes down to what you're building it for.

Good luck guenther....be sure and take lots of pics!

I would agree, go 13BT in a shorty rig.

Im going 1HZ in my 60, but then it CAME with a 2H.

Yep, as Greg_B said, the H150f tranny and transfer is one long sucker. I have measured the length before but I didn't keep the figures. The reason we made the transfer hang down so low is because we will need to point the output at the third member pinion . The distance from the transfer output flange to the third member pinion flange is only 13 inches or so. Since I am not willing to cut the tub opening (the project is not a wheeler, but a "resto" rig), moving the rear axle backward is not in the cards.

If I were to do it again, I would go with a 1HZ-H55f combo.

BTW, I am not expecting gobs of power out of the 1HZ, after all the power output is almost the same as a 2F.

Ha, maybe normally aspirated!

TURBO BABY, TURBO!

[Radd Cruisers]

Maybe our 1HZ/H55 package is a tad shorter, I just browsed my pics and cannot see any shots of the tranny in reference to floor pan for the 3B.

As mentioned the 3B is about 6 to 8 inches off the fire wall.


Good luck

Here is a picture of my 1HZ with H55 and tcase.

hzj60, whats up with that transfercase?..

I looks like the output on the transfercase is in the center instead of off the the right of the tranny. Is it set up for a center diff. ? or is it just the angle of the pic?
