All good ( except a 92mm bore in a 6 bolt block without sonic testing it ) until we get to what the choice of pistons does to the wrist pin and rod big end. Custom forged pistons, dished or flat top, with pins and rings would be in the $550 - $600 range. They take about four weeks to have made. How much did you save on the pistons after taking into account the extra work on the rods? And then you have a block with cylinder walls that are too thin to begin with, and certainly way too thin for a boosted application. You should have a .155 wall for that - probably double what your thinnest spot is now. Don't believe me, have it tested. Or at least ask other people who have tested these blocks what the results are to give you a general idea of the specs. Just finished explaining to an owner of a turbo b20 that this is why he is blowing past the rings, blowing the dip stick out of the block under boost.
