stock block,built internals

ok …
wanna know what im looking at here…
i know d-series(d16z6 and d16y8) stock blocks with eagle rods and vitara pistons are making 400+ hp to the wheels…

so my question is can the b18a and b18b do the same?
with forged pistons/rods,arp rod bolts,aro head studs and p&p head do the same?

how much boost will the stock sleeves take?
