Yes, I mentioned that I have the GTurbo Bad Boy and big FMIC.
21 fine splines for H150, same as the R151F? I thought the H150 only come with 14 coarser splines.

H151 has 14 coarse spline thick input shaft
H150 has 21 fine spline and thinner input shaft
R151 also has 21 spline and I think a different shaft diameter

Well, I have checked the parts program for the VIN# coming of a 1997 HDJ80 (24 valve 1HD-FT) and for a 1993 HDJ80 (12 valve 1HD-T). Apparently both have the H151 box. If so, what is the application for the H150?
Just as a heads up,
The H150f out of a 1hz 80 has 21 spline input shaft.
The H150f out of a Hdj78/79 has the coarse 14 spline input shaft. The Hdj7x/ vdj7x never had the H151f box not that there's much difference.
If your looking for a h series box, look for a box out of a hdj78/79. Something easier to find would be a GCC spec fzj78/79 with a 1hd bellhousing.
If you decide to use a vdj7x H series box, you will also need the shorter hdj7x input shaft aswell as bellhousing.
You are correct.
The HZJ80 (1HZ) has a fine spline H150f.
The HDJ78/9 has the coarse spline H150f. (Direct fit)
The FZJ78/9 also has the coarse spline H150f. (Need 1hd bellhousing)
The VDJ76/8/9 has the H150f/H152f but needs the 1hd bellhousing and input shaft.
A GCC spec GRJ79 will also have the H150f box but expect the same as with the VDJ series, needing bellhousing and input from 1hd series.
This is a post off the LCOOL forum. It may shed some more info.
There has been much discussion over the years on converting an R151 to a H150 or H151. Some info good some right of track, her are some things I have just learnt by doing the conversion.
If you have a HZJ105 STD you need a h150 box and transfer from a 78 or 79. You need a transfer shifter from an 80 series part time or you can re mount the 79 shifter on top of the adapter housing and modify the linkages you will also have to keep your original transfer lever and boots and re use them . The gear lever from a 79 is 30mm to long, the rubber boot you see from inside the cab wont reach the fat bit of the lever. I ended up cutting the lever in half just below the fat bit then drilled out the centre and threaded both ends. I simply screwed them back together with locktite.All the lever positions are as per original. If you have a GXL you need a H151 from a HDJ100 and transfer case. The gear leaver is further back in these cars. Don't forget to get the gearbox mount with the box you buy. You do not need to change tail shaft length or cross members it is all straight fit. Wire loom will need to be untaped and re done as the reverse switch is on the opposite side of the gearbox. Hope this is a help Darren.

Thanks for your detailed answer, I wish it was that simple for me. In fact, in the part of the world where I am living, the vehicles you mentioned before are so rare that beside the 80 series I have never seen any of the others, neither being driven or being parted out. I have a friend who has a HZJ79, so the 1HZ engine, and there are some 75's also 1HZ powered, but beside these, there are none.
The 80 series are more common, and every once in a while one is available for part out. Most of them are HDJ's, so full time 4X4 with H151 gearbox.
If I'm gonna get a H15X gearbox, I have to buy it from abroad, most probably from Australia. I found this gear box shop in Melbourne, they also offer a cool overdrive option for the 5th, anybody has any feed-back on them?

So why can’t you get an 80 series box and use your transfer case?

If the HZJ105 had the R151 box, then he would need to swap the transfer case input gear to suit the larger H15# gearbox output shaft.

Yes, now I have the R151F, I have re-checked. The t/case is part time, so I guess is the HF1A.
If I would get the H15# box, I would also go for the full time T/case (is this HF2A?)
I'll look for a HDJ80 gearbox + T/case, maybe I can find one in the near future. For the moment there is no HDJ 80 being parted out, neither a separate gearbox, I have just checked all the domestic classifieds websites.
After mid of January, when they're gonna restart work, I'll also ask at 360gearboxesdiffs in Bayswater / Melbourne, maybe they have something already waiting for me. This overdrive option they are offering is very interesting.

Eek that Isuzu clutch plate currently prices close to A$400 through Amayama! But if it works to enable a 300 mm Toyota clutch pressure plate and flywheel to mate to the h150f box that's a good thing.
