Just wondering if this is possible. I am guessing no…
Could you make an IDI that had wet sleeves and 6.9 pistons by using a 7.3 block? I am guessing that this is impossible?

I seriously doubt that it could be done.

I wish it could. That would be amazing. I believe you could sleeve a 7.3 down to a 6.9 but I don't think they are set up for wet sleeves.

Drives really slow
I don't have wet sleeves but my 7.3 is sleeved down a 6.9.

The cylinder walls act as stiffening ribs to tie the deck to the rest of the block, removing those walls and replacing them with wet sleeves would cause the deck to move all over the place, leading to rapid and disasterous head gasket failure. All wet sleeve engines have extra ribs cast into the block that help to stabilize the deck since the cylinder liners don't provide that function.

This. Your current cylinders provide support and strength to the block. Making them removable and that strength would have to come from somewhere else.
The only benefit IMO to a wet sleeve engine is the ability to inframe rebuild, which you'll never do anyways with how little room you have in the engine bay. I mean it's a struggle to get the heads off with the engine in the truck, let alone a liner kit. There's no way you'd get enough clearance to get sleeves out of it straight, much less adding a puller to the mix.
Honestly with how often dt engines need liner o-rings without being wore out, it makes me kind of glad these are parent bore engines.

R and d has a 5 part series on building a 7.3 dry sleeved to I think a .020” over 6.9 bore

Really cool series to watch it’s insanely in-depth which is great as every other idi YouTube video is always 4 pixels and doesn’t cover all that’s neededSimilar threads
