That would result in an engine with the same bore as the VQ30DE and the same stroke as the VQ35DE. It works out to 3318 cc.

Wouldn't you have to bore the vq30de because the pistons on the vq35de are to big?

nope, because he's just talking about increasing the stroke. you can use the vq30de pistons without changing the bore while increasing displacement via stroke. the relevant parts here are crank and rods.

Greddy alredy has a turbo kit for VQ35 350Z, and 260hp base is pretty good starting point for any mods. I'm sure stillen SC will follow soon, I think there will be a huge market if we could use VQ35 in 4GENs.

Yeah, Ive seen on this one site, that theres two Twin Turbo kits for the VQ35 (which produce 400+ HP on the stock setup). Theres also a Supercharger kit available, and im 90% sure its Stillen.
