Looking for some info on a E30 M60 with a auto transmission..

My plans are a M60B44 with 5HP18, 404 DME and loom with a M60B40 front timing case.

Any reason why this will not work?

Car is only being built as a Grunty cruiser not building for racing or drifting.

Now I understand the 5HP30 is a bigger stronger box however they are know for their problems and the 5HP18 is a more reliable box.

I'm aware that their is tunnel bashing required with the 5HP30 but I'm hoping to avoid this with the smaller 5HP18. I will probably use garagistic mounts and notch the sump to avoid the subframe spacers.

If the 5HP18 destroys itself I will likely have a gearbox shop build a strong one.

Has anyone done this combo before, can offer any advice on prop shafts ect?

Cheers

Why 4.4 M60? I don't think the extra capacity is worth the effort.

If I was you I would use the complete package from the donor car M60 and gearbox it came with for the least hassle with the gearbox ecu. The swap is difficult enough.

Yeah I agree..

The 3.0 and 3.5ltr M60s use the smaller 5hp18 whilst the big capacity 4.0 and 4.4ltr use the bigger 5hp30 that require a lot of tunnel bashing.

I know the small gearbox fits on the large motor as both motors have the same bell housing That's not a problem my only problem will be the electronic side of it, just need to know if this will work.
