isuzu 4BD1T swap?!

[PurpleFJ62]

I just put that drawing as my desktop background! Way cool man. Are you going to manufacture this adapter your self or take it to a company and have it done? If you were out sourcing it you would probally need like 10 people of so to purchase one up front, I am shure people would be willing to do so.

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.

What you see in that picture is most of an Isuzu MSA gearbox, with some Austin Allegro gearbox parts welded into the top (I kid you not).
It works, but it ain't anywhere near as pretty in real life as the drawing.
The back end of the Isuzu box has been removed and replaced with a 3" thick alloy spacer and the back section of a rover LT77 gearbox. That allows it to bolt right up to a landrover LT230 transfercase.
I plan to design a better single piece gearbox-LT230 adaptor and put up drawings for other rover owners in search of a better gearbox.

Once I have the model complete, it'll then be much easier for anyone to use it for designing engine mounts and gearbox adaptors. But I'm not there yet. There's no flywheel or clutch in there at the moment.

nice work!

Looks fantastic Dougal!! I threaten to do a solid model of all my projects but that just aint gonna happen. Glad somebody is doing it! I would be intereted in converting from isuzu to a440 also.

If I did do the model I would have skimped and only done the neccesary surfaces because I'm "lazy".

How about doing us a toyota box model then? Even just the necessary surfaces would do.

whats going on with the double booster piggyback turbo?

The usual thing that happens with two turbos.
More boost, wider boost range.
Hopefully.

Dougal: Could you elaborate more on your MSA tranny mods. I have one of those that I would consider using if I could solve the shifter and T-case adapter problems. Do you have any pics?

Put me on that list, too!

Don't hack your gearbox up like mine was. Your best option is to get a cable change gearlever (from any fwd manual car) and adapt it to the levers coming out the top of the box.

The back end of the gearbox is simply unbolted and the adaptor of your design bolted in place. I have the bolt pattern locked down in that CAD model.
You also need to make up an adaptor shaft to mate into your transfer case, then you're all go.

My transfer case is a landrover LT230.

I have no need for a toyota gearbox so I won't be making one myself.
But I'm happy to help with the design.

buy the dieselswapper kit, then marks A440 to SBC and your done, prolly wont need to modify driveshafts.

I asked previously about using the diesel swapper adapter along with the Marks a440 to sbc. I was told it couldn't be done because they were both plates, I assume it would space it too much. Is this correct or do you think they would work together? That would be great, I assume I could swap out my A343? in my 97 to an A440 and make it much better, I am really worried about getting a 700r4 to look stock in the stock shifter location.

i dont know why it wont work, and the shifter would be the least of my concern as its adjustable in herd mount or cable.

 

[rtarh2o]

I don't fully understand how they work, but I think they are both spacers. I think the Marks uses a crankshaft extension as well? It seems like 2 spacers would make the distance too much? I would love it if I could use the A440, anyone else have any input on this?
Thanks - Rusty

I'm going to begin parting out a 62 in a few weeks. If a A440 belhousing would help someone figgure the 4BD1T to A440 swap out I'll send it at my cost on permanent loan. PM me. Heck, I could even see about sending the whole tranny, it's dead.

somebody step up

Dougal-I don't have a toyota gear box yet for any working surfaces.

Euclid-If I had an isuzu here I'd take your a440 and make it work.

I still can't keep all this swap info straight. Which isuzu bellhousing bolts to a440 via the a450 connection? Is that connection on the 4HE model only?

I suppose I should reread this thread and write stuff down!

Keep it up all, Chad

Sorry I have no information on the 4H series bellhousings. Only the Isuzu 4B series.
Well other than the backwards facing starter on the auto 4H powered NPR that I saw at a dealer a few years ago.

bellhousings

I think it was astr who found a connection of 4HE using an a450 instead of the (nissan?) JE trans from previous engines. His post linked the a450 to the a440 I believe. I can't seem to find that post though.

bellhousings

Dougal, didn't Bram have toyota trans dims in CAD of some sort. Maybe you could get the measurements from him for a model w/toyo pattern. Or has Bram already made a model?

I was just pondering that if the isuzu HE motor had an aisin a450 trans which was the same bolt pattern as the aisin a440 trans in toyotas, maybe the HE bellhousing would mount directly to the older BD blocks and widen the adaptability directly to toyota slushbox.

I don't know if I'm making any sense or if I'm even going down a path with potential.

I guess I need to get more powers!!!!
