Message From reading the vg33E is the same stroke diff bore. That bore being 91.5mm. The vg30dett uses a 87mm bore and 83mm stroke. How safe is safe to bore the block out? In theory could you bore it to 93? I know if you bore it out that much and blow the motor the block is useless but if you were to get a new block every time you popped a motor could a 93mm bore hold up to high amounts of boost and what would the final Liter be after this? Also why hasn't anyone tried to get a company like crower to try to make a 3.4L stroker kit? The benefits of the extra .4L and a billet crank I think would yield amazing results.
