ive just been thinking about doing this the last few weeks and started researching. only to find there is a local expert! nice! subbed!

[kred]

Doing gods work Andrew.

I had always wondered about the output shaft on the Jeep boxes, having those boxes side by side has saved me the expense and hassle of finding out myself.

Also, the RWD adapter is 👌

Great work doing the hard yards figuring out the differences between the manufacturers! Being a mechanic for the last 20 years id already guessed the BMW 8hp70 was going to be the way to go but I certainly didn't know the in depth reasons why. Your conversion is very well though out.

[chriskent]

Well done, very informative for anyone looking at this conversion, myself included

Maxxecu has added the ability to add the 8hp to be programmed

Gday, found you channel last week through Macca, I really enjoying the tech side and being into machining I can appreciate the effort that’s going into the adapter plates, Im keen to see how Macca‘a holds up after a bit of gentle Sunday driving 😂, cheers

Have since sold my 79 series but still watching and find mad interesting.

The 8HP50 (2nd gen 45) can do a lot for its skinny case.

The reason why I am looking into 8HP70 swaps is because I happen to own a BMW E38 740d. That's an M67D40 biturbo V8 diesel with a 5HP30. The engine is so heavy duty it is hard to believe when you see it's internals. Locomotive levels of torque potential. And BMW tuned it to limit the torque to only 560Nm, the exact numer the ZF rated these 5HP30 transmissions. Some people tune lightly it to 620-630Nm, but that's right on the verge of failure. At first I thought about 6HP32 swaps as they don't require any adapters if you get the correct bellhousing and they are rated to 750Nm. Then the 8HP swaps in Poland blew up and it is hands down the best option. Why put so much work to get another wasteful sloshbox if 8HPs are so efficient. The instant lock-up and so many cruising gears. I bet could probably maintain 200km/h @ 1800RPM on the 8th as I have the longest 2.65:1 differential.

VERY interesting. I have been dreaming of putting an 8hp70 behind a turbo OM606 - wired into a Jeep Wrangler. Seems that day is getting closer

[mothergoose]

Zero to guru. Wow, you guys really know your stuff. Thanks also for the email response about trans and engine swap options for an OKA. I suspect we'll be doing business in due course.

[eriqrosado]

Very cool to see Luke finks old jzx90 in the shop at simply tuning.
That just tells me whom ever won the raffle, is gonna be thee type of person that’s really gonna love and care for that car. Not only will it be thrashed but hopefully it’ll be taken such good car of it you wouldn’t know by looking at it it’s thrashed!

[Patches-vqcd]

Love all your vids, you make these swaps more accessible to the avrage Joe with every vid. Thanks alot!

[chippyjohn]

Any plans to do an M57 or B57 engine swap, they are excellent engines.

[cezexcezex]

i starting to swap 8HP70 on my suburban from 1999 with 5.7 vortec

[SavageBunny]

Im going to swap my 05 Range Rover, im going to use the swap and ABS off a 330xi I just got, Im going to use an 8HP45X, and an M54, I was going to do an N54 swap, I already have it, but I want it for reliability, with a nice super charger Ill be happy with 400hp, just reliable and on stock internals.

[Avv]

Are there any plans to make 8hp kits to suit fg falcons/ territorys?

[NorthWestSamurai]

I snapped my shaft in the bush once but it was the 70's and things were pretty hairy back then! Luckily the damage wasn't permanent 😅😉

[Nico_i_DCT]

Thanks for this explanation Guys! Have a great week. Dutch regards Nico.

[mrvip]

With Jeep SRTs we run 750AWTQ for years without issue on supercharged applications.

They 8hp70 in stock form can handle a lot more than implied in this video.
