Andial carries the 2.9's (93mm) but I'd warn you that these cylinders are VERY thin and the rings do not seal well when hot.

92's (2.8) are, practically, speaking the largest useful bore size you can use with a case of this stud spacing.

You can use the 92mm Mahles (if you can find a set) with 2.7 heads but you'll need twin-ignition and some creative machine work to get the CR down to pump gas compatible levels.

FWIW, I have one new set of Mahle 92's left.
