Really big bore sleeves

[X2guy]

Looking for some sleeves that accept up to 89mm pistons. Anyone make these. Northwest will make me custom sleeves but I don't want the effort of having to give them all the specs. Time is limited. I'm also going to need pistons so I'm thinking of doing a run of Wisecos.

Can't you just tell them to make them with the same specs as their big bore sleeves 1588BB, just bigger?

And, by the time you remove that much material from your cylinder, won't the port "runners" be pretty small in volume? Maybe you'll have to grind them deeper into the block? IDK???

Ask GroupK. They're doing 89, 89.5, and 90mm bores on 62T cylinders.
I believe Team Scream might, too.

Far as I know, those are custom-made sleeves that you can't just go buy.
