Help!!! In need of an absolutely unobtanium GSXR 1100W part!!!

Whats up guys, new here. I usually frequent the gixxer.com forums but the nice folks over there have sent me this way in hopes that I have better luck... I'm on the hunt for a Superbike Mike (aka SBM, SBM Engineering) 1298cc billet cylinder block for a water-cooled Suzuki GSXR1100. I have a ridiculous amount of time and money into this bike, and I love it very, very dearly, and this is really the final special part that I need to make it everything I've ever dreamed of (aside from commonly available bits for this next motor build).

I know, there's probably about 0.5 of these things in existence today, but I am determined, and literally willing to sell my left nut for this thing. Pistons I'm not worried about. Matter of fact, I would even entertain a damaged cylinder as I have access to some pretty good machinists and I like a challenge. PLEASE, if you have any type of lead on one of these rare things please send it my way, I will pursue it, I'm not here to waste anyone's time!!

PS: While I am on the fence about going FCR, I am also lowkey on the hunt for some 40mm Non-US market BST carbs, if anyone has any leads!

Any help would be much appreciated.
