That is beautiful! I'm sooooo envious!

trans swap?

Ok, still researching my 4BD1T swap into my 97 FJ80. Apparently a cummens 4Bt? will mount to an A440F trans from an earlier FJ80? If this is the case will the Isuzu mount to it as well? Could I put the A440F into my 97? Just trying to find a way to make this work

Go to www.4btswaps.com
I have uploaded a picture and photos showing the 4BD1 bolt pattern. It is not the same as the 4BT or an SAE pattern.

I have run my 4BD1T hot before and also low on oil. With no damage to crank surface or heads.
It takes a serious cooking to damage these engines, the driver would be left in no doubt to what they've just done.

The cranks are nitrided and stay wear free after many hundreds of thousands of km's. After grinding the nitrided surface off, they won't be as good.

dieselcruiserhead: Could you measure up the input shaft of the NPR 5 speed for me? I need to know the length, diameter, # of splines, and the dims of the little bit on the end that centers it in the crank.

Does anyone know for sure tthat the 4BD1 and 4BD2TC are balanced with the flywheel on the motor? I am trying to figure out if its possible to put a spacer between the crank and the flywheel. If it is balanced with the flywheel I would think that moving it is out of the question. If its balanced internally then it might be. Moving the flywheel forward would make it a whole lot easier to mate the H55F input shaft to a clutch disk.

Bram finally getting around to this. Pics enclosed. I'll take a measurement shortly of what the overall height is as the motor is now finally back together...

About 29" long. My guestimation (with head off) is about the same height at the bottom of the oil pan, about 28" or so...


EDIT : I took another measurement of the engine all puit together, with the crossover tube it is about 31" from the bottom of the oil pan to the top of the crossover tube.

I totally forgot that you were doing one... I can't wait to hear how it turns out!!!

GM trans

Still trying to figure out the 97 FJ80 Isuzu swap. Any word yet on an adapter for the A440? If not what about the isuzu diesel swapper adapter to a GM trans and a transfer case adapter to the Toyota case? I have read about this but just wondering if it has been done or is really possible? Which trans, I am leaning towards an auto.
Thanks

for an auto you could run the 700r4 and the 80 transfer case, same as the guys doing 4BT swaps in 80's.

 

[rtarh2o]

Getting somewhere?

Still researching, I am going to make this work. First, how are they adapting the 4BT to the L/C transfer case? Another option is this that I found on AA websitd "Mark’s 4wd adapter kit to allow you to adapt the GM 4L60E hex bolt to Landcruiser HF2A transfer case" The Isuzu Diesel Swapper kit says it is for the GM 4L60 trans, and from what I have found my 97 fzj80 has the HF2A transfer case. Seems like this should work, it would be nice if I could avoid the $1600 in adapters though! Any ideas?

Does that tranny hold up with a motor thats half as powerfull as a Diesel?

 

[rtarh2o]

If you are talking about the 700r4 I read on one of the 4bt sites that they had to beef up the 700r4 to hold up to the 4bt, I assume the same would have to be done with the isuzu? How about the GM 4L60? I assume it will hold up since it is the trans in the truck they did on the isuzu diesel site? Anyone know?

thats easy, import a 1HZ from canada for 8-10K or so, no money spent on adapters, pretty much a bolt in. or just run E100 in your cruiser and feel good about not burning dino fuel. i dont know what to tell ya, modifying from original costs money no matter how ya do it.

half a,,, what??

the 700r like all auto's not built for low revving engines have problems with line pressure to operate properly for a good lifespan, so, they need to built with lower revs in mind, its easy, no big deal. the input shaft from the torque converter is the weak point, but they have been running around behind 4BT's for a while now with minimal to no problems.

 

[rtarh2o]

I considered the 1HZ route with no luck, I was told a half cut was the only way to go but I have not had any luck finding one. There was a 1HD-t for sale near me for $7,500 which I thought was a good deal but passed on it after several people told me all the bits and pieces would be expensive and hard to find without the half cut. The Isuzu sounds like an easy conversion to do as far as wiring if I can get the transmission thing figured out.

[rtarh2o]

So which trans would you go with, GM 4l60 or 700R? I am pretty sure I can still buy the adapters, trans and isuzu engine a lot cheaper than the 1HD-T Toyota and spend the remainder on other things. Does it sound like I am on the right track in my thinking about the transmission/transfer case adapter?
Thanks

i would do the 700r, by the time its all said and done you should come away a little under the 1HZ price. why not do a 4BT swap that are already being done in 80's?

 

[rtarh2o]

Wouldn't the same problems be involved with the 4BT or does it mount to a GM trans? The main thing I don't like about the 4BT swap is the 4" lift required. I am building a daily driver with quite a bit of highway driving intended. I am also under the understanding that the Isuzu is a bit quieter. Any progress on the bellhousing talked about on this thread?

Man Dougal, I just opened the model you sent me. You have been pretty busy! I'm glad to see that you have the motor side of the bellhousing in there. I have the automatic transmission bellhousing in a CMM right now. It has taken me a few hours to learn to use it but I think on Monday I will be able to get it done. Then to figure out how solid"works".

Good to see it worked.

I've done a lot more since then, I'm taking the opportunity to clean up the engine and paint anything that needs it.

Nice solid modeling. What is the tranny you have it attached to?

that is awesome. I want to get my a440f out on the floor , measure it up, and send you guys some information.

great job.

Trans adapter

Do these drawings mean you are working on an adapter? What transmission are you using? It would be nice to be able to use a Toyota trans to keep it looking stock and eliminate the linkage problem. Let me know, I would love to have one!
